- How to Set the Correct Air Pressure and Amperage for your Plasma Cutter. By matching the correct air pressure settings with the correct amperage settings for the material you are cutting, you are not only extending the life of your consumables, you are also saving money. You are using less electricity, your compressor is running less, your machine is running in the optimal zone and you are getting a better finish cut which equals less grinding and material prep.
I too used one setting for everything. Not anymore. Check out the video and give it a try. I think you will be impressed.

Great video, I have been using the “more power” technique with dubious results, so obvious when your told. Many thanks from NZ
Thanks man. Me too. Now I get many more cuts from my consumables and better cuts. I thought I should pass it on :)
Thank you Brandon for making and posting this video. I've been so frustrated with my Cut-50. It just wasn't cutting straight. So with the suggestions of your video and learning to go slower and have the torch close to the metal I've finally been able to cut metal that is more than 3/32 with a good cut. Keep these videos coming. BTW don't worry about those who say it wasn't really a 1/8" piece of metal. The chart I found says 20 amps at 30 PS1 for 3/16th down to 1/64th. It doesn't make any difference.
Thanks man glad I could help! When it starts cutting crooked that generally means the contact tip needs to be changed out
Good job Brandon, enjoyed the information and the project. Thanks for sharing.
Thanks man! It's fun to get out of the shop sometimes :)
Outstanding!! Just really getting into plasma cutting and have a Tomahawk 625.. When you showed your Amp/air chart I immediately went to you page and copied it. Have done a bunch of cutting but still having a few glitches with amp/air... This should hook me up. Temperature now 78 degrees so it's out to my shop to enjoy weather and new knowledge. Thanks again.
Thanks Fred! That chart should help your cuts considerably. It did mine.
Very helpful vid Brandon finally the thing I was looking for - that table is great !!
Glad I could help! Thanks for watching and commenting!
I certainly copy that, the table is invaluable, cheers
Thanks, I downloaded your chart and realized that I was way off. Used the guideline for air pressure and amperage and was finally able to plasma cut without tons of blowby and scrap.
Thanks man! I used to do the same. Crank it up and go but what a difference. Your consumables will last longer too :)
BRANDON did enjoy your video downloaded it so i can watch again & again thanks (isle of man)
Thanks man!
This is very helpful! I will be looking for more helpful videos from you. Thank you!
Thanks! I appreciate your interest!
Good information about the air pressure. I would have just cut one end with the 2 holes and kept the bracket end as is.
Just drill 2 holes at the end you cut and cut tabs then bend the end over and weld the seam done. This would save a lot of time and consumables.
Thanks man! That plasma chart was extremely valuable. Also I ordered the same respirator you have as mine is a tight fit under my hood, so I end up not using it much. Thanks again!!
Glad I could help! That respirator is the thinnest I've found. It fits under all my hoods
Great advice -- I have been using WAY too high pressure (for many years...and often getting crummy results) -- THANK YOU!!!
Glad to help :)
i learned many things in welding & fabrication from you .
well done , thanks.
Thanks man! I appreciate your support and comment!
wow.. no, bad habits is all anyone will learn.
@Navaluk Thrasher your watching a channel that gives beginners tips on welding and fabrication. Maybe you should make videos and show the rest of us how its done.
@@navalukthrasher9269
The worst thing i know is a man jealous like a women.
If you know better than Brandon then make videos and show us the right way.
Great informative video Brandon bro and I add an extra filter and air dryer to my compressor when I'm running my plasma cutter
I have a water separator hooked up to my compressor but it's nothing fancy. If I added a filter the consumables would probably last longer, but they are cheap so I dont bother
@@BrandonLund yep there cheap I agree just replace them
Hi thanks for the info just used my cutter first time before your setting guide video melted the gun and it caught alight as did I and shedtable lol so ordered new gun put it fire first obviously then found your guide I did exactly the opposite, haven’t worked out how to access the chart you mentioned in your guide but have time to find it while awaiting new head . Your guide is ace wish I’d watched it first still I think I’ve learned a new lesson in life thanks for your excellent explanation makes perfect sense
Thanks Brian! Sorry about your mishap. Hopefully things will go smother next time.
Love watching and learning👍
Thanks for watching! @BRENT Smith
Thank you man this tip help me big up!
Thanks! Glad I could help :)
EXCELLENT VIDEO. Very helpful for us novices. Thanks...
TBoone
Thanks man glad to help!
Yep this guy is very smart and definitely knows his shit. Wonderful videos man I learn so much from watching your videos very informational. Keep posting it really helps newbies like me.
Thanks brother! 👍👊
Great instruction on use of plasma which I have, but I also have band saw and would have cut about 1/2" back behind the hook end on the arm allowed for that 1/2" at the other end, clean cuts champer and weld the edges being square from the saw, but I do like my plasma unit.
Nice!
Thanks buddy great video
Glad you enjoyed it
Always a great job
Thank you Roger
Brilliant video thank you 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Glad you enjoyed it Thank you!
Good job
Thanks buddy!
Great video thanks. Struggling to find the plasma cutting setting chart
Its under "photos" in facebook.
Got it thanks
Thanks for the info. Now cutting clean. The electrode is reversible in that torch. When burnt down just flip it over. Thanks again.
Glad i could help and thanks for the tip!
Hi Mr. You are a professionel worker. 1 K Bravo. 2020 03 14 Saint-Joseph de Mékinac, Trois-Rives, Québec et Labrador.
Thank you! My wife and I are planning a trip to Quebec this summer!
Thanks for a great explanation regarding correct pressure and amperage settings for plasma cutting! I do have one criticism however regarding the use of a dust mask to protect against welding fumes, etc. As an Industrial Hygienist, I would recommend that your viewers review the correct filter cartridges for the respirator in use to protect against the fumes being produced. Organic vapor cartridges protect against the fumes produced by the paints you’ve pointed out, and metal fumes require additional filtration not provided by the organic cartridge. The dust filters in use on your half face respirator only protect against large dust particles such as are produced during grinding operations, and that system will not protect your respiratory system from the most insidious exposures found in welding and cutting. False sense of security I’m afraid...
Thanks again for the info on pressure/amperage settings, and please don’t consider my criticism regarding safety gear as being a negative review. Just educational information to protect the health of you and your viewers!
Thanks for the great compliment, however this is taken directly from Millers website "Once you start arc welding, the ozone created by the electrical arc produces fumes that require a more robust system of respiratory protection. Since the face shields worn to protect from infrared restrict the type of respirator and cartridge or filter that can be used, many welders prefer soft P100 filters like the 3M 2097 Particulate Mold Filter P100 because they have a layer of charcoal to absorb fumes and organic vapors and also can block far more of the particles carried on the air. The 2097s can be worn on the 3M 6000 Series half-face masks or the 3M 7500 Series which is made of soft silicon and is more comfortable when worn for long periods of time" ~ I don't doubt your expertise but I also cant dismiss that Miller Welders is promoting the same exact respirator I use on the channel. I feel they would have a huge liability issue for promoting wrong PPE. Please dont take my comment as challenging you. I'm just relaying on the PPE that many rely on in the industry (excluding a PAPR of coarse).
Thank you. Altho I’ve worked with plasma several times in my career each machine has its own story per say. Your chart came in handy with a similar machine I just purchased. 😉😁💯✔️
Comment on the fabing: I bevel everything also. It’s just good practice.
Someone once told said it’s not necessary to bevel a fillet weld.. but I told him to F🇨🇦ck off.. when the strength is needed it will alway be there!
Like hand rails. Some never beveled their joints and grinded their weld smooth. Journeymen welders.. smh
People.. you have to weld with anticipation of the worse case scenarios. The biggest impact for sheer strength. Hopefully it never happens but if it does you’d wish you’d have taken the extra seconds to bevel properly if someone dies because of your welding.
Lol rant over!
Thank you! 👍👊 a little extra time in prep pays in the end. Better job, better pen and a better looking bead in my opinion.
Like the chart will use, my only suggestion (after the fact) would have been to cut from the bracket end and just weld in a small piece at the open end for the bolts that way everything would have stay square and less grinding.
Good point. Thanks for watching!
That's what I was thinking. The end piece is a simple plate tacked on the end. Way easier and quicker.
Good point. Thanks for watching :)
You do great videos keep it up I would of cut the other end off the rebuild would be easier
Thank you
You're welcome :)
Thanks
Thanks for watching!
Thanks for the info. I'm new to plasma and it was very useful. Where can I download chart?
Thank you! JOIN OUR GROUP facebook.com/groups/brandonlund/ then open the "files" section. There you will find the chart along with lots of other good info.
Thanks a lot for this vid. I am a beginner and learned a lot from this. What I would like to know if am to buy consumables how am i going about it? My brand new cutter is a 240 v 50 amp. Tks. God bless.
Thanks Joe. I just go to Amazon and you will want to buy the consumables that match your torch. In the directions to your plasma cutter it will say which model you have then just buy the ones that fit it. Thanks for watching and I appreciate your support.
i have just got my self PLASMAARGON ICUT 60P , every thing works great , but it works and cuts same with ground connected or not to the job , i dont want to use and damage the machine , when welding ground connection is easy to know as will not work , but as you know ground may look ok but is not un till welding starts that you know, so i would never know if i have good ground or not as plasma works with or with out, i have used industrial plasma cutters before , but for my retirement i think small cheep plasma is all i need .
Hmmmmm. I wish I would have seen this comment earlier. I was using my 50 amp imported plasma cutter earlier today for an upcoming episode. I don't think mine will work without the ground. If the ground is bad, the ground clamp starts sparking and arcing against the metal until is creates its own good ground.
Great video. Where is the link or app for the plasma cutter settings? .I subbed to your U tube and went to your Instagram site but I guess I missed, where to get the app or apps you referred to. Looked at your list of you tube video’s, wow great list, I’ll be busy watching most of them. Really great stuff, thank you, you really deserve all the subs you get.
Thank you very much! I appreciate your support! The plasma cutter chart is on my FB page. If you go to Brandonund DIY Builds on Facebook you will find it under the photos tab :)
Hi Brandon, I have just purchased a plasma cutter, I went to faceBook to get the settings list you had in this video but could not find it, would be able to publish again or tell me how to find it, your videos are great.
@Steve Chang congratulations man! Plasma cutters are a huge time saver. You can find it on facebook in the "photos" tab or you can find it on TH-cam. If you go to my youtube page then click on the "community tab" you will find it fairly colse to the top. Thanks again! I appreciate your support!
I'm guessing you went with flux core here to blast through the paint on the parts? Clever fix for wintertime tire storage. I only have one set of tires out here so my latest project was welding together a better pliers storage rack for one of the drawers in my rollaway. I'm a bad new welder so I screwed up some of the welds which means now I get the "fun" of grinding today!
Hey man we have all been there. God knows I've ground my share of bad welds. The flux core burns a little hotter plus it was already setup from the last project so I went with it. I like the idea of a pliers rack. Mine are thrown in my toolbox. They are hard to organize.
Brandon Lund angle iron with flat bar tack welded to it. Used some 1x wood as the spacer between because it's just about the width of the handles for one pair of pliers. After I got it done I spray painted it that cheesy red they use on rollaway tool boxes.
@@matthewhall5571 that's why I love the TH-cam comments section! There are some crafty guys on here. I might have to build one. I really like that idea. Of coarse I will give you credit for it if I do .😁
Great video nice job , I hope to get a plasma cutter someday . We have a rash of bad guys going to different streets getting into cars and trucks a few are on home cameras but none have been caught , any tips ? Thanks TANK
Thanks man. A plasma cutter is super handy! We have car break ins too. I just make sure my doors are locked. I've only had my stuff broken into once when I was on a job in New Hampshire. They stole 5 buckets of tools from an unlocked job box. The idots were weaklings apparently because they left the buckets in the woods line because they were too heavy so I got everything back.
@Wroger Wroger good idea!
I'm about to use a plasma for the 1st time. Looks like we both opted for that 200$ Amazon model. Comes with no instructions so here I am watching your video. No helmet settings either.
Great video as usual but can't help wondering why you didn't cut from bracket end and just weld on plate with fixing holes. Each to their own I suppose. Great tip on plasma though as I have all ways just turned up full power. I'll find you on facebook and follow and pick up that chart. Many thanks.
Thanks for watching. I chose to do it this way because the c-channels that come off the bracket had to be oriented in one direction for some and the opposite for others and 2 needed to have an offset which would have resulted in 2 - 3 different fab methods. I somewhat explained this at the end. Doing it this way kept it simple by cutting in the same place and ultimately preventing me from making a mistake. Thanks for watching and commenting!
Makes sense now you say that. I must have missed that. Thanks for taking the time to reply. All the best.
What do you recommend for the pressure regulator for the plasma cuttter? Thanks
They come with one already installed. If your referring to the correct pressure setting, just navigate to my facebook and click the photos tab. In there you will find a chart for setting the correct pressures. Thanks for watching!
It's the law of more. If enough is just right, more is better.
Its more better as my little grandson would say lol.
thanks :-)
You're welcome!
Hey man! What kind of glasses are you using? Thanks
I might have a link down in the video description. If not, they a green tinted cutting glasses. Shade 4 I believe.
Please explain the application of a 0.03” plasma cutting nozzle size, vs 0.06” plasma cutting nozzle.
Thanks
A smaller nozzle works better on thinner material and if your running on 120 volt. The larger nozzle works better on 240 volt cutting thicker materials.
Add 1 for subscriptions. I am a qualified NZ4711 downhand arc welder. Bare minimum standard so this is a satisfactory lesson about cutting entertainment to make use of. Thanks. I'll be looking for that table you flashed onscreen during this video
@Jack Richard's thanks man I appreciate the sub! 👍
Is there a pilot arc on this plasma cutter that you are using? Or are you just holding the tip in the sweet spot where it creates and arc. I just got one and the tip wants to glue to the piece that I want to cut
Its a pilot arc.
Hi Brandon, nice job. Are the adjustments general? My 40 amp plasmacutter manual say 4 bar (prox 58 psi) standaard for all thickness. I wil try this weekend with to cut with 20 amp and 30 psi for cutting 2 mm steel. Greetings from Holland
30 psi 😉
Hello Brandon, I practice with 20 amp and 30 psi on 2 mm steel. It works goed. Bath i think with 30 amps i can cut faster with a cleaner cut. Dit you try that ?
Honestly Eric I have typically just set it and run everything high but lately I have been using this chart and i am getting better cuts, less sparks everywhere, longer consumable life ect. You might have to play with the settings a little to suite your machine but so far I'm very happy with the overall results. Thanks for comments and watching. What are your temperatures in Holland. Yesterday it got down to freezing temperatures here in Maine
Thank you Brandon, i will play with the settings. Temperatures nex week are nights about 4 gr Celsius (39 f) and daytime prox 8 gr Celcius (45 f) . Most claudy and every day same rain.
It was the adjust accordingly part I was looking for what are you looking for in the and when you find a isn't penetrating do you increase amp or air or back down if it's closing back up on you. adjust what accordingly pressure amps both would speed you move make a difference.. new to the game sorry
Much is trial and error. If you follow your air and amp chart that will get you close then you can experiment by adjusting your amperage up and down slowly while leaving the air alone to see what setting is best. It doesn't have to be exact
Is the shade needed for plasma the same for tourch? #4? Thank you for doing this!
That is the recommended shade but I can't see the line at a #4 so I go as low as my hood will allow which is #2. I also mig at #6 which also isn't recommended but I can't see otherwise.
@@BrandonLund thank you sir. New sub.
Thanks man I appreciate it! 🙏
I don't have a Facebook. Is there any place else you posted the chart?
Let's go
Brandon!
Lol I love it. If you go to my TH-cam Chanelle and click the "community" tab, you will see it there also 😀
@@BrandonLund very grateful sir.
The feeling is mutual! I appreciate you watching and commenting 🙏👍
I saw that the claw end was two pieces prior to cutting and would have used that as the three inch section then just weld a plate on the end with the wall mounting holes. Much easier and would look much better.
Thats the great thing about metal working. There are usually a few different ways to arrive at the same end result. The reason I did it this way which was a little more time consuming is I wanted it to appear as though they hadn't been modified.
Thats what i was thinking as well
this might sound dumb ,but where did you hook up the ground cable when you welded?
Usually I clamp to my able. I don't remember specifically for this one but thats usually how I do it.
Привет Brandon, хорошая работа! Тоже есть плазма, но пока в коробке лежит)) (OGAREW)
Hi, I enjoy the video.
I'm just I'm just wondering why you made the extra cut and just don't work from the back end, I'm a little confused. Was it maybe that you did not have tools to Bend the steel, to make the back plate again?
Im not sure. Its been a while. My goal was to make it appear as though it was never modified.
I just think out of the box. But still good video
Great video Brandon ! You did an awesome job at explaining everything regarding setting up the Plasma cutter and modifying those steel brackets.
I just got the very same "Cut 50" 50 amp plasma cutter for Christmas 2020 and I stumbled on your video whilst searching TH-cam on it !
What sort of air compressor do you recommend for this plasma cutter ? I noticed that some of more dearer plasma cutters have a built in air compressor... I searched online yesterday on Google and managed to see what's inside one of these top end plasma cutters that have the built in air compressor and I was very surprised to see that it was just an ac motor with a twin air pump (1 air pump bolted to each end of the AC motor) and NO air tank ?? !..... Everyone I know seems to say that it is important to have an air supply that comes through an large compressor air tank for smooth plasma cutting, Is this true ? as the manufactures of these expensive top end plasma cutters seem to build their plasma cutters without an air tank and just a air compressor unit !
If it is possible to just use a twin air pump as an air supply to be able to plasma cutter without having to use a massive heavy bulky air compressor and tank ?, please share your thoughts on this ! Thanks man for your help !
Thanks for reading man and all the very best for 2021 👍👍👍
I don't have any experience with the more expensive on board units so all I can reference is what I have. I'm using a 5hp 30 gallon compressor. With that said, its more than enough to run it.
@@BrandonLund Hi Brandon, Thanks man for your input. No problem mate, I understand that you can only reference what equipment you currently have. I have been researching this and apparently you can run a plasma cutter with no air !, although for finer, precise cuts they say it works much better with a suitable air supply, So I will wait until I can get a good capacity high flow air compressor which is about 24 - 90 liter and that should be ideal to run mom's Xmas present lol
Take care bro and keep making these fantastic videos !, we love them here on TH-cam ! 👍👍👍
Thanks buddy and I appreciate your support!
@@BITTYBOY121 Unless you're doing production work, you can have a fairly small air compressor unit, but maybe use an extra tank on it to give you the continuous run time you need, if you're making short cuts and can wait a half a minute between them you shouldn't have a problem even with a pretty small one
@Joseph D this is 100% spot on advise.
I like his face the best
Unreal
@@BrandonLund your the shizzle my nozzle
What kind of dryer and oil separator do you use for your air lines?
It's just a basic setup for automotive painting that I bought at Napa around 30 years ago.
I just ordered a similar plasma cutter,so thanks for the video..But,i would done that job in another way.Why cut both ends,when just cutting the other (With the holes) would be enough.
Then just make some small cuts on the sides,and bend the middle section 90 degrees and drill two holes...
There is always more than one way to skin a cat. I went for the one that closest resembled how the factory did it even though I could have saved time doing it differently.
So, do you place the consumable face against the metal you are cutting or is it best to be 1/16" off the cut?
I generally drag the consumable across the workpiece but that's not reccomended. Your supposed to leave a small gap which also increases you consumable life.
My Hypertherm came with a drag tip which keeps the electrode from dragging the metal being cut.
Will those amperage / psi setting work with most 50 to 60 amp plasma cutters
Yes sir :)
Marking holes to wall, then moving shelf away from wall 20cm and drilling holes. Moving shelf back to touch wall and... CAN'T BE SO HARD ;)
@Jari Kaija It wasn't that hard at all :)
Thanks, this should speed up the figuring out stage even my cutter gets here.
Thank you and congratulations on your purchase :)
Great info on plasma settings. Shame video didn't stick to the subject and didn't wander off for most of it into shelf brackets and welding.
Would be good to see cutting various materials with the wrong settings and an explanation of problems.
This video actually isnt great. I have a better one "Plasma cutting 101". I forewarn you, i like to go off topic and ramble a bunch of nonsense just to irritate my viewers so i can receive disrespectful comments. It seems like it worked 👍
@@BrandonLund And use up my roaming data allowance unnecessarily.🤔🤔
But I'll have a look at the 101.
And a Q Brandon. I've got Parkside Pilot Arc so do I need to make any adjustments to your excellent table? Just tried on 4 and 6mm material and table settings seemed to work pretty well. I found with stainless 4mm, I just needed a couple more amps than mild steel 4mm.
@@colinstone8096 that table will get you really close for most machines whereas its based on output amperage VS air volume. Spot on about stainless requiring a little more than mild steel and aluminum will require about 10% less than steel.
Brandon, sorry to bother you,,,,,I bought a CT312 Inverter and came with one plug and cable, it can go 110 or 220 volts. I dont know if it came with 110 0r 220 install. Iam afraid to hook up 220 plug on the cable . Do all I have to do is change the plug? Please help
Without first hand knowledge of that machine I cant say for sure. Generally if it's a dual voltage machine it will usually come wired white, black and green. The green is ground and the white and black connect to the positive terminals of your 220 volt male welder plug. I would write the manufacturer or try googling that specific machine to see if you can get a wiring diagram. I dont want to see you fry your machine.
@@BrandonLund Thank you Brandon
How do one get a good ground on a painted piece of metal? And how to start an arc on a painted surface? My cutter ( primeweld) struggles to keep the arc lit .
@petrus e For the ground clamp you have to find a spot where its clean bare metal. As far as keeping the arc lit, that's where having a pilot arc is a huge benefit. If you don't have a pilot arc it helps to get the metal free of paint.
@@BrandonLund Appreciate you took time to comment/reply my question.The obvious reason for asking was watching you doing a cut without any previous clean up of the piece.It simply shows that not all plasma cutters are created equal
Thanks man! I'm sure my ground had a small spot that was making metal contact but the rest the torch can burn through :)
hello congratulations you can increase the cutting depth of my plasma Telwin thanks
Your machine will work best if your setting match the material your using.
Does the chart work for all plasma cutters? Im new and just got a Flaring 500 for $100. No instructions.
Yes, it will get you very close.
Can I find the chart for the settings by mail or so? I'm not on Facebook.
And what about the airpressure if there is a minimum setting to make the machine work?
Going by memory I think 30 is a minimum. I have it on Instagram also if your on there
Does the tip touch the metal when cutting
Yes. I use a "drag tip" that allows you to do it...but if you don't have a drag tip then you should hold a small gap
Hello Sir . . . I just purchased a Cut 50D plasma cutter and noticed that your dial is not synced with your digital readout. Is that normal with plasma cutters? My new PW machine does the exact thing . . . dial is three amps off from digital display. Thanks.
I think its fairly common.
@@BrandonLund Thank you for the response . . . new to welding and plasma cutting . . I really appreciate what you do!
The 3m 6291 mask with a 2091 filter is now $30.00.
I shall down load the chart! thank you.
We can thank Corona supply Vs. Demand for that :)
It seems the weld at the hanger is more detailed and would require more work to cut and prep. I would think it would be easier to cut 3 1/2" from the bracket, prep and weld a plate to the end.
Good point! @Michael Dvorak
I cannot find the link to download the chart. Can you post it here for me?
TH-cam and FB don't play well together so it wont let me. If you go to my FB (link in the description) then click on the "photos" tab. It's in there.
Very good video - direct, informative, easy to understand and to the point without wasting time on repetitive content. I like that tell what you are about to do and what you are doing while you are doing it (instead just showing it without any explanation). I Subscribed.
I appreciate that man and thank you for the sub! It's much appreciated!
Do you have your plasma chart in METRIC please?
@CJW Sorry I don't but I will be working on one in the near future
I have a herocut CUT45D 220v plasma cutter. The max amps I can use is 20. I'm cutting AC compressors for a living. And I have the PSI set to 75. I still can't get it to cut well. Am I doing something wrong?
@Prince Noah 75 psi @20 amps is too much. Try lowering your psi according to the chart. Some other things to consider are making sure your air is dry by using an inline dryer. You can get disposable ones for cheap. Make sure your consumables are fresh. If you were saying that your only able to get 20 amps out of your 45 amp machine than it sounds like your internal electronics are giving up the ghost.
@@BrandonLund Ehh, sorry. I didn't word that right. My cutter is actually new. XD I can change the amps by turning a dial. But if I turn it past 20, the breaker trips. The outlet and breaker are only rated for 20 amps.
Hmmmm 🤔 with it plugged in and turned on (and not cutting) you should be able to max out the dial and it shouldn't pop the breaker. If you are on 120 power than it probably won't display past 30 or 35 amps. On 220 it should display the full 45 amps. My plasma cutter blows the 20 amp 120 volt breaker in my shed if I cut above 25 amps for more than maybe 30 seconds. I have to turn off my compressor while I'm cutting because my compressor in the shed is on the same breaker so I'm constantly waiting for the air to replenish between cuts.
@@BrandonLund I just re-read your previous reply.
And then I found the owner's manual for my cutter. Good thing, too. I found that I need replacement parts, the shield cup broke. The ONE thing they did not give a spare of! 😂
When the new parts come in, I'll try lowering the PSI and see if that'll help. I'm wondering if the psi is making the cut cool before it's done cutting? It yes, that would explain it. XD
Well at least you found out the issue and it wasn't something internal 👍 if you look on my community tab I have posted a pressure ND amperage chart to.save consumables
What happens if you just use the max amp on the metal? does it melt it?
@Seahawks forever It will still work but the cut wont be as nice and the consumables will wear out much quicker.
@@BrandonLund Okay thanks!
I've got to get a plasma cutter but that seems like it would've been easier and faster with the cold saw...
Good point. It would have been faster for sure but if someone didnt have a bandsaw or cold saw this would be a good alternative to a grinder wheel :)
Is the chart located somewhere besides Facebook? I would like to have it
Facebook is the only place I've uploaded it
Bummer. Thanks for replying
Your owner's manual has a chart. Download a new manual if you lost or burned your original
Is an ordinary air compressor can also be used?
Yes. That is exactly what I am using.
@@BrandonLund how much horse power is required?
@ NAS Venture Mine is a 5hp 30 gallon and it's plenty. You are generally running it around 30ish psi. I've also used a pancake compressor but it has to recover depending on how much your cutting.
Bandsaw cut and weld one plate with the holes drilled in. Done.
The bracket orientation had to be flipped in order to work or I would have. I show this towards the end of the video.
would you not have been better off saving the length from the other end and just cutting out the bolt hold plate to weld into the more complicated end?
Possibly. I don't remember why I decided to go this route but I knew this way caused more work but I went this route anyways because I felt it would have been a better product.
You could of cut 3 1/2" from the bracket side and remove the 2 smaller sides 1/2" and bend the remainder lip 90 degree inward.
That would work for the center brackets but the end brackets had to be flipped 90 degrees so I could have access to bolt them to the wall.
He made a lot of extra work for himself
Sometimes doing it right takes longer but in the end hopefully creates a repeat customer. Keep in mind the brackets had to be rotated 180 degrees on the end wall
Yah, definitely should have cut the 3.5" from the other end.
Actually, if this is anything like running torches there are a couple of main reasons for the setting instead of simply running your amps (heat) and pressures (blow through) at full tilt: If you’re cutting lite gauges running high heat your material will overheat beyond just your kerf of cut and the material will pool and fill in behind you as you move forward in your cut which is frustrating to say the least! As for air pressure, you only need enough pressure to push through your material. If you’re cutting half inch you have a lot more material to push you flame through or arc through. But if you’re cutting thin shit then you’ll pressure requirements to push your flame or arc through is far less.
@4R NORTHWEST I never really thought of it but yes your right, it's very much like using a cutting torch. I wish I would have mentioned this in the video for those that are used to using torches. The one thing I really like about this is the cost. As you know gas is expensive. All you need for this is air and electricity, although we will always need torches for heating and bending this makes it nice to keep gas cost down
It seems to me that it would be cleaner and easier to cut off an appropriate length from the center section and then bolt the pieces together.
Possibly. There is always more than one way to skin a cat
I asked for a plasma cutter for Christmas. Wife said "no ! You'll cut your fingers off ! "
I got the divorce papers all set to go.
Merry Christmas , old bag !
Tools will always be there for you! Lol. Merry Christmas 🎅
Mine just bought me one. I didn’t even remember mentioning it to her.
Hahahaha rub it in! 🤣🤣🤣
Why didn't you cut the length from bracket end towards the wall end and then weld wall attachment end on.
No particular reason. I felt this way was a little less labor so I went with it.
@@BrandonLund dude im not bashing your video. I like your videos alot and watch most. But you put your handy dandy gauge on and clicked it back and forth with space on both sides. there for its not 1/8 bet if you go nack with the gauge ant put it on 14 gauge it will be a tight fit being 14 gauge material
@@rolfbach2721 its metric but 1/8 gets you close.
@@BrandonLund gauge is gauge 12 is 12, 14 is 14, thats universal. I think!!?
@@rolfbach2721 yes unless the material your using is metric or stamped. It didnt fit 14 guage and 1/8 was just slightly loose as you pointed out. When metal is extruded its thickness is consistent. This metal was stamped into c channel with presses which can result in the material being thinned in the areas of bends and where the dies were pressing. Its either metric or 1/8" but either way an imperial measurement was close enough of a measurement for what we needed. I frown from using my good micrometers for rough in work and its not necessary.
Your could have cut little farther down on mount to legs side and cut little extra off the wall side mounts and re welded the channel together
Good idea man!
I don’t do scumbagbook so where else is your chart
I can't say as I blame you...I will try to get it uploaded to Instagram tonight. TH-cam doesn't have a way for me to share it or I would.
Is there anywhere besides facebook to get your chart. I have personally banned facebook. Thanks! ✌️👽
@Name I can't say as I blame you. If you go to my TH-cam home page then click on the community tab. It's posted there also
Why wouldn’t you just cut the brackets to length and weld in a plate at the end with two holes in it to avoid all the grading and cutting of the brackets that attached to the shelf?
@Brent Begay like most things there are usually a bunch of different ways to accomplish the same thing. Knowing I had to flip the orientation of some of the brackets I felt this gave the cleanest final product even though I knew it wasn't the fastest way of doing it.
I just have to comment on what you said about the breather being good because it’s 3m. 3m knowing gave military bad ear plugs because they thought it would be cheaper to fight lawsuits. Until it happened lol they are about to go bankrupt because they knowing damaged the hearing of soldiers who actually need their hearing which can be life and death in combat situations. But other than that great video and good safety practices.
I heard about that. I'm sure they didn't set out to intentially harm people. It's unfortunate some got hearing loss
First thought watching this was "WHY isn't he cutting just the hole plate off...." ... then saw in the comments you said about bolting them to the wall, then the thought is "Why not cut two inches from the hole plate and an inch and a half from the mounting plate, spin it 180 so you can mount to the wall and just cut up some of the scrap for an internal plate for strength and weld it all together" ... but hey, to each his own.... Now to go find that chart.....
Found the pic, Easy Peasy, go to his FB page, click PHOTO's, and there it is :D
Honestly, I was trying to keep it looking as though the factory had done it. Obviously I took the more difficult approach but for the reason I explained.
@@BrandonLund Aye, can't argue with ya, as I said to each his own when it comes to fabricating things... I think we all have our own unique way of getting to the same conclusion :) Some just get there faster than the rest of us ROFL :)
To be honest, why would you buy expensive wall supports and have to cut them up and modify it when a piece of flat with an angle bent halfway does equally well?
Ah, because the customer bought these, it came with the supports, it didn't work, so they paid me to correct it. This has to be a trick question....
Weres you cold cut chopsaw
Which one, I have 2?
very nicee videos I really liked all your videos but your like button in channel not work. all the best
Thank you! The like button doesn't work for this video or all of them?
@@BrandonLund All of them master. I really liked all your video but I can not give a like to your videos all Respect
I thought with plasma cutter it's about CFM not Psi?
Psi is its cutting force. Cfm is how long it can maintain that steady force
Keep the front on and adjust the back
Ok
