Cheap Welder, How to Flux Core Weld Exhaust " Budget DIY Exhaust"
ฝัง
- เผยแพร่เมื่อ 9 พ.ย. 2019
- I remember failing at welding my first custom exhaust using flux core wire back in 2009. So today I tried at redemption with the old cheap flux core. It’s not going to be the prettiest, but it can be just as functional as the exhaust that looks like Jesus welded it.

You cant knock him. He got it done at home. Most people would of paid 600 bucks and wasted a day waiting for their car 😂😂😂 Good job buddy.
Right I learning
Honestly sometimes it’s better to pay someone else. Than get some shit stuck in your eye lol
@@streetlegalbuilds7644 change your name cuz you ain’t building shit..
No choice in these Democrat states... nobody is allowed to touch an aftermarket exhaust anymore here or get faced with a 35k epa fine. So I'm either allowed to let it leak or diy it and hope for the best. Most people are letting theirs leak for a couple years I'd imagine. The smog is way worse now anywhow... 🤦♂️
@@misterbulger chances of getting fined is slim to none, also it sounds like you aren't searching hard enough to find someone to work on your modified exhaust.
Pretty good tips. I've had a lot of experience in this situation. Try just going straight and not weaving. Give it a good second or two with each bead (without blowing holes obviously) but don't let it cool all the way off in between pulses. There's no need to wire brush it in between pulses. Just stop for a second, watch the glow of the bead die down, and before you lose site of it in the darkness of your hood hit it again. Over and over until you're done. You'll get a much better "bead" look. Overlap them a little like you were but keep going with the bead until you have to rotate the pipe. Good luck!
I probably and up having to read this comment.
Exactly my method.
gonna try this for sure thanks for the advice
Thank you for these tips
"People never want to be part of the process, but they want to be part of the outcome. The process is where you figure out who's worth being part of the outcome.." Great video bro!

Welding with flux core isn't bad when you know what you're doing. 🤷♂️
Welded my exhaust for my car, first time using flux core. I have to admit however, my welds turned out way better then a lot of these guys on youtube.
@@zerodegrees8 Prove it.. th-cam.com/video/62moqa9dICw/w-d-xo.html 😁
@@TPVPRO not hard at all. Especially if you don't insist on Harbor Freight crap. And a simple can of anti spatter spray works wonders. Oh, and it helps to leave ego behind, and use the best tools for the job...that usually arent at Harbor Freight! 👊🏾🤣🤣🤣
Is it just me or did I feel like you were talking to me /about me the entire time😂
I’m literally sitting here laughing with a giant smirk on my face like this guy must know who I am
Just weld the damn thing and quit playing with it like it’s a peter.

Haha i died
You try dragging a bead with a 110A welder.
Right. Lets see yours.
I've only got a little over a year with welding experience, and obviously watched this to learn what to do or not do, what I'm doing right or wrong etc... and I know I'm pretty ok. Nice clean welds are common. Anyway, this is a really good way to start welding, I know a few pros who stick to this or a similar method. I personally lower the temperature so that I can weld faster and with longer lengths without burning holes into the steel. If your temperature is already at the lowest possible and you're having hole problems, just dot weld until you finish the job, don't risk wasting time, effort and money trying to be faster with a long string of weld. I'm probably forgetting some tips I've been given and have learned, so if anyone has any questions I'll try my best to answer as accurately as possible
Your main problem is not enough stick out and using a welder with only a high and low settings. Been flux core welding for years even on 20gauge sheet metal. Give yourself a minimum of 3/8" of stick out. The results will amaze you
“Works way better than tryna cut shit with a grinder” i felt that one🤣😭
We all quietly watch this knowing we all have been there. Love the video, so make some more!
I've learned (through welding 25-30# of flux core wire) that the weld puddle has holes because the torch was stopped too quickly before the weld puddle was hot enough to properly build up.
You don’t need to stop and clean just keep welding and clean after, this is going to take a freaking week to complete
for real!! buddy would finish his exhaust weeks later
Slag will go into the weld. Not sure if the flux in the wire is enough to prevent corrosion.
The weld needs to cool anyways
You absolutely need to clean the slag off or your weld will be contaminated and corrode. Wire wheel on a drill or a grinder makes quick work of it
After 15 years welding at work finally bought a Titanium 125 flux welder from harbor freight. No problem welding exhaust. Assuming it was you lack of experience or knowledge not the welder.
Give me an OX/AC Torch and a closet hanger any day
Unlike some other videos, there was a lot of useful information in there. Thanks!

Thanks for the video I haven't elded in over 10 years I learned a little in autonomy school but I'm not an auto body worker
I am about to get one from Amazon and this video helped a lot! I will be welding some catless exhaust system so it doesnt have to be pretty and this is much better than paying 500$ to someone.Thank you!
If punching through, you are dwelling too long. Either move along the seam faster (in short puddle jumps), or zig-zag on each side of the seam to spread out the heat. (It also helps to have a machine with continuously-variable heating dial instead of a toggle switch - where LOW is still too hot.)
Try rotating the pipe on a wide metal V-channel to move along the seam. (Or, place inside a slightly wider pipe.) For convenience, clamp the ground lead to the V-channel metal (or outer pipe).
Try a longer stick-out (3/8"-1/2"). It preheats wire/flux more than the base, and is generally better.
For flux-core, DC negative is much better than AC (although a mix of both can be ideal).

I was super scared about doing some exhaust work because welding rigs are like the price of my car but ty so much for introducing me to that little thing cheers!
Nice! I want to get into welding for car exaust, and my gosh does this seem easy!! Great video!
Great video dude. I'm currently in the process of redoing my exhaust from the downpipe back, the current one is an absolute hack job! I know it won't look the prettiest but if it doesn't leak I'm happy. Only pain in my ass is all the bends and welds I have to make in order to route the exhaust properly, I guess that's what I get for owning a slammed euro! Thanks for the tips, doing it on your own is always more impressive and worth it in my opinion!
Probably the best advice from all vids ive watched, going slow and cleaning after every short blip seems to be a good trick. Ive got an exhaust to try and fix but i remember totally failing with thin pipe years ago with a stick welder. Thanks really helpful 😄👍😎
Thanks for taking a little time to make this video. I have had no time to practice and several times I need something welded.
Out in the sticks so..we make it work.
Your getting worn holes because your not holding the welder on it long enough for it to fill the hold. The biggest thing about welding is reading the puddle. The more you weld the more you will understand what I mean
I’ve never used a flux core welder but after watching this I’m positive i never will haha
Good decision! 😂
Joe Simpson flux core isn't that good for thin metals but for thicker metals it's great and simple to use. It's probably the best to learn first imo
@@rsmithmedia3287 Joe Can weld really good. He is just giving me a hard time.
@@rsmithmedia3287 I completely disagree, welding with a proper hardwire machine is 1000% easier
Weld.com has a video where they bust myths about flux core, they're not bad. They definitely have their place. Growing up on a farm, they were great for field repairs with a generator when getting back to the shop wasn't an option. A lot easier to pack up, don't worry about how windy it is, and don't need a massive generator, everything fit on the rack of the atv.
After i took my car to the muffler shop and they rip me apart with a large bill i decide to get my own welder and learn how to do it my self🤷♂️
So, good/great video, ive tried for years to weld exhaust ( cost to have done $$$), here is what ive discovered, "modern" pipe from big box stores has an "aluminumized" coating on them for corrosion, 25+ yrs ago it was naked steel, you would see it with flash rust on the shelves, the "aluminized" coating is messing with your welds, a little sand paper application and its mostly gone and easier to weld, your blow throughs are somewhat normal for flux core, thats why "most" shops braze the pipe instead of weld, also part of those $$$ for a shop to do, your video is helpful and good, thanks for that, wish YT had been around when I started, for what it is your video is extremely helpful and makes people less scared to try it at home, which is a good thing, way too much heres $ and ill pick it up now days, thanks for the great vid
I have to make a cradle to fit a hayabusa in a kitcar and only when got the hang of it and getting a good weld that the cable runs out and the new one is totally different and I am struggling to get it set up like the previous cable. I then noticed its different in size by 0.1mm, so minimal, does it make that much difference.
I like the way you describe your weding skills. I suck at welding too but im not scared to try and would rather try my ass off and fail than not try at all
Mind blowing tip: If you spray the work area with non-stick cooking spray the splatter won’t stick. I found this tip on TH-cam and it actually works. 👍😉😇
I'm going to have to give that a try.
This is a joke right? The oil in a weld will spit like crazy
@@davidludwig4286 nope "pam non stick spray" works
Great video! Looking forward to getting into welding for my exhaust. Beats using epoxy, clamps, and wraps!!
I actually think it came out pretty good for what you’re working with... flux core never looks great and it’s difficult to see while welding. Also it has a different sound than regular gas mig welding so you can’t really make it should sound like “sizzling bacon”. I think your settings were at least in the ballpark
You did very good actually with a flux core welder . I give you props 👏🏼👏🏼🤌🏼
I started with a big 220 Lincoln stick welder angle iron and box tubing also frame work on my car. I used a fluxcore welder .30 wire 2 heat stage high / low and wire speed was adjustable. Now I did exhaust on low heat overlap back and forth motion about 1 inch welds never had a issue blowing through the pipe. Never used gloves on a 110 either not needed unless you have sensitive skin. I also use the nozzle on my welder.
Thank you for that! Struggling with my own system at the moment. No option for some old cars but build your own. I shall take your suggestions in hand!
Great video for a beginner like myself. Thank you for sharing brother
I don't why you put your welding skills down ? That exhaust pipe weld job passes my inspection. Give yourself an A+ for your effort !!
Bro this is ridiculous but props to you for actually doing it.
I put a H-pipe and dual exhaust on my car with a HF flux core welder. I had better luck with the .035 wire but maybe just because it was a better brand. Also took the nozzle off, helped a little. But really the hardest part was welding on the ground with no lift. The welds look like 💩 but it's together and no major leaks.
Nicely done!!
Thanks for the video, I'm about to turbo charge my Subaru outback h6 so this should help me to build a manifold!
You can do it for sure, it just takes longer with the flux if you want it to look decent. I have another video on anti-spatter it required less cleanup. I think with a little more practice the welds can look cleaner.
There's no way someone is turbo charging his car after appreciating the content of someone that can't weld himselfe.
How’s that turbo ej30/36?
@@joshrepik sold the car before I got around to it
i looked it up in my dictionary and, goggles is next to godliness, cleanliness is nowhere near it.
You did not look then. www.dictionary.com/browse/cleanliness-is-next-to-godliness
What is ur set on ur flux cored. Thanks u
👍 love the attitude
Not a welder but this got me prepared lmao
Honestly, is having the most beautiful beads really important with exhaust welding? As long as you get good penetration without a bunch of blow throughs, I don't see how it is inferior in any way with a few spatters. It's just exhaust after-all. I say all that because I think you did a great job and I think it's great for guys that need to build something at home on a vehicle that doesn't need a super fancy shop job. Just cheap, strong, and effective.
Exactly! Who is going to crawl under your car (assuming you don't have a show car) and look at your weld job on your exhaust? (If you hear someone in the dark of night say, "What a shitty welding job!" Then you will need a new cat tomorrow. In that case, I guess a shitty welding job is a good burglar alarm.)
@@rickb2267 exactly!
Nothing grinding and painting can’t fix 🤙🤙
a grinder and paint make a welder what he aint
I have to say that was very smooth welds for flux core would you be able to soon make another video with flux core welding 👍
I got it down a lot better now im releasing and exhaust video soon.
Bro nice job u helped me I gotta change my wire
Soapy water sprayed on work piece is the best anti spat. Use it every day! Keep working at it. Flux core sucks but it sticks shit together!!
Slow and steady wins the race 👌🏻
That weld looks good to me. I have never welded but my friend has with a cheap harbor freight transformer Flux core welder and his looked far worse and always leaked no matter how many times he tried to redo it.
I would consider buying and learning on one of these for a couple of projects. The main one being I want to remove my catalytic converters on my "100% offroad only" truck and build a frame for a gas powered fan for a hot air balloon.
Some of the earlier welds *looked* poor, but were they really inferior as far as strength and durability is concerned?
I love to watch welding videos, the problem you're having is due to stopping, next time instead of going downwards out of the puddle, go upwards into the puddle, if you're welder is turned completely down you either need to reduce your feed speed or move faster through the puddle, the flux cores stuff makes a gas shroud around the puddle so you need to carry on and also point the fan at you rather than pulling / pushing air around the puddle, I'm still a total beginner, thicker stuff is super easy to get right, but the thinner stuff is a nightmare to get set up for and get right, loved the video
the one from everything I know flux core is supposed to be dragged. Not pushed. You can push mig all day. Not flux core.
All these experts in here were given huge money from dad to buy big Miller welders and beards. This is a 110v flux core welder, you can't drag beads on exhaust tubing with these things they suck ass. This man is doing God's work.
I figured out how to lay down decent beads on the super thin pipe. Just try to help the budget guys / girls that are listening thanks for the support good sir. th-cam.com/video/62moqa9dICw/w-d-xo.html
@@TPVPRO You definitely have helped me improve!
You can get some coolant to spray while your cutting to increase longevity of the blade and also maintain cleanliness
InShould I pay 150 for my flex pipe from my car exhaust to be cut off and weld a new one or should I buy a 125 flex welder and learn myself and do it myself. They both about the same price
for clean up go out and get a sanding disc or flapper wheel. and you don't risk having a cutoff disc exploding
I’m not the only one that fabs exhaust with fluxcore after all.
Do you cut those pipes dry? Shouldnt you use lubrication when cutting like that?
I use an Esab Rebel that does flux core or gas, I can’t really say I’ve had any problems using flux core in fact it suits me better being outside most of the time, nothing worse using gas on a breezy day.
Thanks for sharing!!
This is a pretty late .. but I would recommend just getting a mig hardwire set up. I have the Lincoln with the flux core / mig combo. Welded a jeep frame with the flux core, plan to do my trucks exhaust with the mig. Flux core is exactly like stick welding. Runs hot as hell etc. just a thought, it’ll look a lot better and be a lot less work.
thats wild! never seen such a tiny mig torch!
I've been watching a lot of these videos lately of buying and using the $100 flux welder , im thinking im gonna purchase one for my Chinese scooters exhaust that keeps breaking off my header on my gy6 150cc scooter keeps breaking I'm needing to have it weld reinforce I know if I go to a local shop they will charge me more then what this welder would cost and if I keep buying replacement headers at $30 a pop well I'll be paying way more in the long run ! So I believe my best option is buy me a flux core welder and a welding helmet shield learn how to fix my own exhuast issues and future problems that might happen down the road thanks for making this video it was a good tutorial video 😁👍
Yeah, making flux core look good is a challenge. But it's just like anything else. The more you do it, the better you'll get.
Now to be clear, I'm NOT a professional welder. I'm a professional mechanic by trade.
But just a little advice about flux core welding. You want to make sure you get a machine that has the correct polarity. Flux core needs to be run electrode negative. When used in that polarity you won't have so much spatter to clean up and you'll have much better welds.
These really cheap machines, such as the black Harbor Freight flux core machines, are wired electrode positive. Which is why they have problems. I know it sucks, but try to save up and spend that extra 75 or $100 to get a machine that is wired correctly. It's well worth it in the long run. But if you can't, I do understand that very well. Just get some scrap and start laying beads down. Do that for as long as it takes for you to get used to the machine and can lay down some welds that will actually hold. It just takes practice.
Much respect for you TPV!! For being big enough to readdress this and for giving folks good advice!!
You're The Man Brother!!! Y'all be safe out there!!🤠😎
Oh and I gives a f@#$ that this is three years old!!
Well done, I'm using a Harbor Freight and it's really ugly patching all of the burnout holes. Not to mention at the lowest settings and the pipe is thin and old 1 3/4" stock on a scissor lift.
Thanks again for the video.Cross my fingers on my 68 Camaro exhaust.Thank god it’s under the car we’re no one can see my shit set up.
I don't want it to look nice but if the weld holds up then I'd be happy with it.
That is not bad at all 👍
Amazing!
I liked the video after the 3rd “sucks” 😂
@11:50 "Aw man, that looks like CRAP". Looks better than mine! :) :)
I have flux core welded exhuast b4 , im no welder but i turned my machine way down so not much heat and moved the torch fairly quickly kept the weld puddle moving had pope welded all way round in about 4 welds, only had to stop to turn exhust round and never burned thru, cheapest welder i could buy to outtta lidl, was like 90 euro and 4 euro for roll of wire, cant beat that
Did u use flux core on stainless steel?
I have it's actually a little easier to weld.
Great job, flux core is crap for 1mm steel.
function over form 👌🏻
You can get 0.23 wire as well
First, my dude the anti spatter repels metal so spraying it on your weld surface is going to give you fusion issues. Second, you need to lower the gun angle so that you are just barely aiming into the weld pool. To much will cause you to hit your slag wall and to little will cause holes. You can go downhill with flux....I ran downhill on a harbor freight $99 special set on high voltage at 7 wire feed. ...i did both sides of a true dual exhaust and it sounds great. You're getting the flattening and holes on your tacks from running the flux like a mig
...increase your stick out to 1/2 to an inch.
What is the sound track? That beat is sick!
3:36 sounded like some bars perfect with the beat
This shit has me dead 💀💀
So you're wearing a bare metal ring and sitting in a metal chair. What happens if the grounding clamp slips off while you're holding the metal pipe and connecting a +100 amps to it?
Nothing because there isn't enough potential to overcome the bodies resistance let alone create an arc through clothing to the skin. In order to get the amperage necessary for welding, the welder uses a transformer to step down the voltage trading potential for current usually 20-40VDC which at high amperage is enough to create an arc to something conductive like stainless. There is some danger with the ring though because if the wire feed is too fast, he gets it stuck and he has a small spark gap between the ring and the piece it will create a ton of heat in a short enough time to cause a really bad burn.
@@justin456 www.ncbi.nlm.nih.gov/pmc/articles/PMC6304335/
@@MattJonesYT The case mentioned here was not caused by a loose or detached ground. The gentleman struck an arc on his ring that was itself grounded out on the workpiece which is completely possible. Had he taken the clamp and firmly attached it to a metal chair he was sitting on naked he still wouldn't be able to reproduce this injury, the heat was secondary to an already struck arc.
Is this pipe fitting
fluxcore is KING!
Them no glove weld are savage
Then, if you have to, grind your weld to smooth it out. But if you lay a good weld, well in that case you want to leave it as is and boast to all of your buddies you did it in one pass! 👍
No disrespect to the pros, but u were more helpful than them, thank u

I got another one coming out soon. I was able to get it down a lot better. It should be helpful to DIY guys like myself.
@@TPVPRO those kind of vids man, they are the Holy Grail of DIY guys👍💪
Breathing the flux core fumes in conjunction with your repetitive flute song would drive me nuts.
Anyone know where I can get 4” piping?
Making a smoker?
The Homesteader no, making an exhaust. Got the pipe now though
Nice 👍
Nah - that "technique" shows you didn't do your TH-cam!
My 110v flux core welder burns through if held down more than 1sec on the lowest voltage setting.
I have learnt through a long process of trial and error that this is the way to weld thin steel with a cheap flux core welder. I was hoping for a revelation that I was doing it wrong from this video but hey ho. I don't bother with ant-spatter, just use a flap wheel on clean up. The newer DC flux core welders look the way to go but they are not cheap enough yet to make the change - and I need to find someone to buy my AC machine first :( .
I herd the DC ones are pretty good.
I have a Lincoln flux machine with option for co2, I paid about 400 for it and it’s not all that worth it to me. We use the ln-25 suitcases at work to weld kilns and I like them a lot better.
Welding with a flux core is such a process! Haha! Love the video. No gloves too, next level man!
I put them gloves on in my other video. But indeed, Flux Core on thin metal is a lesson in patience.
The reason why there is a hole is because you are too close of the weld, your flux wire doesnt heatup enough before touching so it does a point in it
If it’s slag, you drag.. how do you think muffler shops do it?
I have 2 videos on my channel of just that it you want to check them out and see.
