Hey Bob, Thanks man for taking the time out of your schedule to personally call me and walk & talk me thru my TIG dilemma this week. There is definitely a huge difference between you and unnamed welding channels... You wanting to teach and help folk learn welding, and those others who just dont even bother answering a question on the comments. Your a Man of integrity! And I truly appreciate you taking the time with me. Thank you! BTW- the banter and kidding around thing "The Camera guy" is great!
I do not have any of those expensive modern welding machines, I run a Miller Shopmaster 300a and a Miller 351 Syncrowave machine, I tig weld everything that comes in my shop door from Aluminum stainless Mild steel and alot of the specialties. If you know how to weld you do not need one of these expensive machines. I run Argon but mix my own Helium and Argon for aluminum, run DC with straight helium on thick aluminum and a pre heat. It all comes down to experience and how you were taught. Bob you were taught like me on the job and from the old timers that pays off in the real world. Always learning never always knowing is my motto, your videos are great, the keyboard jockeys might have other things to say but those who do this for a living think differently.
ian bertenshaw....wow I'm not a welder..yet! But I remember back in the 70's being shown the carburization method for finding the bending point of Ali. Good memory thanks.
I was looking for a proper video of aluminum on DC! My teachers were asking me to try to aluminum on dc because I always like too try challenging myself and they notice it. Anyway, thank you Bob!
Thanks for showing that you can indeed DC TIG weld aluminum. I'm in the processes of getting a multiprocessor welder; your video has helped my decision making.
Good information for the hobby welder with a dc only machine who on occasion needs to weld moderately thick aluminum pieces. I always appreciate Bob Moffitt's excellent instructional videos!
In the mid sixties I welded on the Saturn V first stage. It was all DC, but we (being on time and material) actually scraped all the to be welded surfaces with a three edged scraper, then wiped all surfaces with MEK.
THANK YOU. I'm fairly new to welding and have repeatedly seen post after post of people saying you cannot weld aluminum with DC. Once I saw a few (very few) saying you can (with argon or helium) I started looking for the real pros...like this! Obviously AC is better for thin stuff but for 1/8" and larger it seems that DC can do really well with the right tools and technique.
I got the PowerMTS251si for Christmas. I only mig with it right now (auto body tech). Knowing I can start to learn Tig on aluminum with it is awesome. Thanks for sharing.
thanks for another really informative video bob. i have been welding for over 40 yrs (doesn't mean i'm a welder) and i have never seen anyone weld aluminum with dc and helium. i have been running a 300dx for the last five years so i have never had to explore other options to weld aluminum, but that sure is a trick worth knowing.
Welding is a hobby that I enjoy and I use it to make and fix things around the house. Can't justify the super equipment that the professionals say is required...REALLY APPRECIATE how you're demonstrating the practical application of "real world" equipment that we of limited funds and time can afford. I'd ruled out DC only TIG because I have a few small projects that must be built of aluminum. THIS demonstration has made we reconsider trying TIG since I can afford a DC only rig. Thanks for all the work and practicality that you are bringing to the hobby welder community.
Hay Bob; i worked for MacDonald Douglas during the B1-B bomber Fairing Fuel tank Program we did for Rockwell International. We used a combination of half & half argon-Helium on a vary high strength aluminum called 2219 and welded it with 2319 for Hand welding but the automatic that i used was 100% Laboratory grad Straight Helium.
Thank you so much!! I have this exact machine and was debating on trying to weld aluminum as I am new to welding aluminum and so many people online say "you can't use a DC machine". I'm going to go get smaller bottle of helium and practice now! You guys rock! Thanks for your always informative and detailed videos that get right to the answers with clear explanation and demonstrations!! It's invaluable knowledge and deeply appreciated!!👍👍👍
It's the same tank fitting. CGA 580? The flowmeter won't read right. Some flow meters have different scales so they can be used on different gases, if you just remember to look at the right scale.
Great. I've been DC welding aluminum for 3-4 years, process is kinda grungy but nice welds and I'm doing it with a Thermal Arc 160. Thanks for the great viedos, been watching all of yours.
It matters because not all AL alloys can be welded with DC TIG and Helium is extremely expensive and hard to come by in many areas (twice as much as Argon in my area). Helium is also a non-renewable resource and will probably be highly regulated in the not too distant future.
Thank you!!!! About time we had a discussion on dc machines running aluminum 👌🏼👍🏼👍🏼👍🏼👍🏼👍🏼 I love running it! Have some work coming up that'll smooth my craving lol good work guys!
Another great Friday: A corn dog, a beer and a video from Mr. Bob that I learned from. I guess those Everlast machines are liked by quite a few welders. Thanks Bob!!!!!!!!!!!!!!
I got turned onto this just about a year ago from a buddy. What he said makes sense.....this is how they welded aluminum 50+ years ago and its still how they weld aluminum for many processes like dies and such. Thanks for showcasing this Bob!!! Also, were you running DCEN or DCEP? I have seen guys run both ways but will different tungsten sizes due to the heat concentration.
Brian Streufert. It is DCEN. This will give a deeper penetration weld with Aluminum versus AC. This is also used extensively with welding vacuum chambers. DCEP won't weld thick materials, but cleans the oxide off.
I really appreciate this video I was under the impression aluminum could only be welded on AC period end of discussion so I am super stoked about this knowing I can do some aluminum practice with me DC TIG machine
Wow someone who finaly proves aluminum can be done with dc and helium, thank you, what grade heluim would you recomend ????,it seems the dentists and hospitals get the good stuff and the welders get whats left so ived heard!
Awesome vid. Didn't know that. Our Miller Rep. Even said it can't be done. Thanks alot. You've just opened new doors. Thanks again. Love mig Mondays as well.
Best video yet! If you don't do a lot of TIG aluminum (like me) it's just what you wanted to hear! The thing I like to know is Everlast PowerMTS 211Si vs the ESAB Rebel EMP 215 ic in a head to head comparison. Bob has used both I believe and would be the perfect man to do the comparison.
Tony Baggett Hopefully the Everlast PowerMTS 221Sti will be released soon and he can review it. Would be nice to have a complete Multi function machine.
Coz F I agree the 221 is going to be sweet. But I heard Everlast has them at an introductory price of $2000 which is a good value they said they'd retail at $2700 which I doubt. The Rebel and the 211 are more similar with just a around a $500 price differences. I fell like the 211 has more features but the Rebel is more intuitive.
Coz F the Rebel doesn't but I wanted to compare models with similar price ranges and features. The 221 is going to be superior to both because of the features and AC/DC Tig but it's in the $2000 as far as price.
From what I've seen on TH-cam the DC- with helium gives good penetration. There isn't the cleaning action of AC, but the oxide floats. DC+ with argon good for thin aluminum and gives the cleaning action but you need thicker tungsten.
Are you using E5356 for the filler rod? If so, that "black soot" is Magnesium oxide. Personally, I have been very satisfied with welding Aluminum as DCEP with MIG wire. The production rate is phenomenal compared to TIG and I have been getting complete penetration on 1/8" thick material.
Edvinas J. I was wondering the same thing??? I know my maxstar 200 will do it but i was curious if argon would work if that's all you had at your disposal...
It is interesting if it is possible with argon or not and why? Because helium much more expensive also have to buy dedicated bottle for that and etc. Probably cheaper will be to buy ac tig than weld with helium and dc .
You can get more heat transferred from the arc into the puddle with helium. Even a little helium blend with argon will affectively increase the capacity of your machine.
I didn't know this was possible, thanks for sharing! Helium is certainly more expensive than argon, but way cheaper than an AC machine if you already have a DC machine like I do. What grade of Helium were you running?
Darn you're a funny feller Bob, but your a better teacher! I have a tailgate and 2 sidebars that I have to build for my welding truck. I'm not as muscley as I once was. My tailgates are too heavy. I needed to watch my Sinsai to remember how to do this process. Thank you Bob and Camera Guy.
Been doing this on trailer/field repairs for years. Lincoln 305G efi with just a scratch start rig. Not the best, not the neatest. But cheap and durable and only extra purchase was small tank of helium. An old fart a used to work for taught me this, was a hell of a welder. Not that it matters but i still to this day have never scene anyone able to weld pipe like we would with tig with an acetylene rig, ol harry probly forgot more than ill ever know
Wait so this is only possible with helium? What about the top side layer? I was taught you had to do AC for aluminum to get past that oxide film with out blowing out the bottom material.
Can you do 5056 Aluminium on DC tig or does it have to be only a Certain kind of aluminum and what kind of filler rod is needed for this process. Thank you very much for all the information. Tabe
I have a 160amp dc tig. Tried today on aluminum, gas at 25 and 30. Wouldt puddle, filler rod didnt want to stick and just cranked heat until base metal melted a crater. Is type of helium grade critical? Metal was cleaned.
Try using thicker electrode and put it in DCEP and much lower amperage(or you will eat electrodes) and wait for cleaning action then start adding filler.
Mr Bob you have me interested! I heard you could do this so I tried not realizing argon is not correct! It was a mess! Now I know why... thank you very much. I guess I do t need a ac machine after all!
Lo moraleja de esta historia es que no necesariamente ocupas una máquina muy cara de AC con alta frecuencia para soldar aluminio. Dice que aún si tu amoeraje no es muy alto puedes precalentar el metal y soldar a menor amoeraje.
@@CesarGarcia-qy4ux Para el caso de chapas finas, tu maquina debe contar con arranque en HF, no puedes calentar para brincarte la hf. En materiales mas gruesos como el que se muestra en este video podrias arrancar precalentando y aun sin hacerlo (hasta 1/4 de grosor). Imagínate los tugstenos sin hf por arrastre. Puff!
I never thought to do this.. my welder is dc only.. would you sooner use dc tig, or aluminum stick? Those are my only options.. im just a hobby welder so nothing structural really
Anything would be better than aluminum stick! It's hateful, everything is wrong with it. Messy! The worst job you do with whatever setup you have now would be better and cheaper than a good day with aluminum stick welding!
Looked up the machine on the Everlast site. According to the picture and the location of the cables, if that is the MTS 251Si then Bob has it set for electrode negative. also the tip of the tungsten did not ball so it must be - Oh and thanks Bob, now I have to price out some helium for my cheap 140 machine. any more bottles that I need? LOL
You would probably have to go higher. Afterall helium is the 2nd lightest element, so it does not like to settle around the puddle like the heavier argon would.
Thanks Bob for the great video. I already have AC/DC Tig (Syncrowave 210) but am always interested in alternative ways to "skin the cat." A video discussing He/Ar mixes would also be helpful, for those times when a bit more is needed out of a machine for a one-off job. I've managed without helium thus far, but wouldn't hesitate to run to the nearest party store for one of the small 8.9cf balloon cylinders if needed. Great job & thanks again.
I have had a great time welding with Argon and about 10-20% Balloon-grade helium. I'm definitely a beginner! You notice the difference instantly! Bright shiny puddle, the whole business seems much more lively. I let a friend try it, I was mixing the gases by hand off to the side. I let him get started and weld for a few seconds. When I let out the Helium he yelled "Wow! Look at THAT!". It's a great demo. As it happened, I was completely following a weldingtipsandtricks video on this topic.

Gallagher Metal Works Right on man! Thanks for the support.
We used to use the soot from an oxy torch to indicate when Aluminium was close to melting for oxy welding .
ian bertenshaw....wow I'm not a welder..yet! But I remember back in the 70's being shown the carburization method for finding the bending point of Ali. Good memory thanks.
Weld.com you can use a Sharpe to preheat the same way.
Thanks for making the video! I had no idea welding aluminum on DC was possible!
If you can get your hands on some helium give it a go.

Are you on DCEN or DCEP Thanks
The black is just the same as when I’m using my mig welder. It’s nothing lol. People are crazy when it comes to aluminum.
Ive been weldin for 18 years. Why did i not know you could run aluminum DC? Mind blown
What would be the best machine to weld aluminum pipes thin material?
Point well taken Bob for general fabrication DC tig with helium why not.............absolutely
can you use argon instead of helium?
I got turned onto this just about a year ago from a buddy. What he said makes sense.....this is how they welded aluminum 50+ years ago and its still how they weld aluminum for many processes like dies and such.
Thanks for showcasing this Bob!!! Also, were you running DCEN or DCEP? I have seen guys run both ways but will different tungsten sizes due to the heat concentration.
Brian Streufert Probably DCEN. From material to electrode for the "cleaning action"
Cleaning action (material to electrode) is DCEP, not DCEN. That is why I am asking for clarification. You can weld it both ways.
I had read a long time ago in school that in the old days they used DC reverse to weld beer kegs. Back when AC machines weren't very common.
Brian Streufert. It is DCEN. This will give a deeper penetration weld with Aluminum versus AC. This is also used extensively with welding vacuum chambers. DCEP won't weld thick materials, but cleans the oxide off.
No cleaning action here!
I really appreciate this video I was under the impression aluminum could only be welded on AC period end of discussion so I am super stoked about this knowing I can do some aluminum practice with me DC TIG machine
Saw another vid of a guy using argon and stick rods and it looked ok.
So glad i came across this. Lol I was one of them ppl that would say well you can't do aluminum on these cheaper DC tig stick welders. Awesomeness
How do feel about pre-heating using a quick arc only pass before a dabbing pass?
Wow someone who finaly proves aluminum can be done with dc and helium, thank you, what grade heluim would you recomend ????,it seems the dentists and hospitals get the good stuff and the welders get whats left so ived heard!

Could you use 100% argon?

You can get more heat transferred from the arc into the puddle with helium. Even a little helium blend with argon will affectively increase the capacity of your machine.
So theoretically thin aluminum with hi amperage should weld with strait argon ?
It's possible. We've done it in the past. You need a fat tungsten and thin material.
Same CFC as Argon?
hi can I welding cast iron or aluminum cylinder head cars by dc tig ?
Thank sir for this video..i almost spent way to much with ac dc tig machine ....thx air bob..
Sir
Can you DC TIG with pure argon
Could you do a similar process with dc mig with helium?

Absolutely Amazing. Again, thank you so very much Mr, Moffatt.
Yeah but how thin can you go.? Could you do 2mm or 3 on helium. This is the big question.

Tried today on aluminum, gas at 25 and 30. Wouldt puddle, filler rod didnt want to stick and just cranked heat until base metal melted a crater.
Is type of helium grade critical?
Metal was cleaned.
Try using thicker electrode and put it in DCEP and much lower amperage(or you will eat electrodes) and wait for cleaning action then start adding filler.
Have you ever tried it useing argon (cheaper)...if so how did it turn out?
Mr Bob you have me interested! I heard you could do this so I tried not realizing argon is not correct! It was a mess! Now I know why... thank you very much. I guess I do t need a ac machine after all!
Can you use Helium at lower that 150 amps?
What was your gas mix?
100% helium?
Mr. green 100% Helium is correct
Can you do this with 100% argon?
Cameron Latiolais my same question I guess no would be answer
@@chadburgess5348 If its thin something below 5mm thick you can use dc and 100% argon since you can get half cycle cleaning with dc.

Hell yes, that is the shit I'm talking about. Thank you Bob for putting it to rest for some of the people that you do not need ac for aluminum
Please what number of amperage are you using?
you're a king ... thank you for everything ... I'm looking forward to a new video ... greetings from Croatia!
Would the cost of the helium not not pay for the upgrade to the 221 with ac
learned something new! Thank you!
Now that was with straight helium right. What flow rate. The other thing .... your heat curve changes as you welding. Thanks.
You would probably have to go higher. Afterall helium is the 2nd lightest element, so it does not like to settle around the puddle like the heavier argon would.
It does not work with argon?
Thanks Bob for the great video. I already have AC/DC Tig (Syncrowave 210) but am always interested in alternative ways to "skin the cat."

Bright shiny puddle, the whole business seems much more lively. I let a friend try it, I was mixing the gases by hand off to the side. I let him get started and weld for a few seconds.

Do not use balloon gas. It is not as pure as industrial and scientific grade helium.
