Most people think that the only way you can weld Aluminum is if you have an AC welding machine; and in many cases that is true. However, if you are really in a pinch and NEED to weld Aluminum, but all you have is a DC machine, this is how you can do it... And NO, you don't need helium for this, it is done with 100% Argon!

From what i read. For thick aluminum where you need penetration, DCEN with helium (costly) was the original setup before going to AC with argon.
Just when you think it cant be done an experienced tradesman shows a trick Mind Blown Thank you Mr. Tig.
This is the best thing i've seen all day. I want to try welding aluminum, but i'm not made of money to spend on an ac machine
bradley morgan hear, hear!!
WOW!!! Learn something new once again, thank you very much for showing this. Because I didnt think you could tig weld Aluminum with the setup of DC.
Wyatt: Tried this out on 1/8" aluminum and got some pretty decent beads (for me , maybe not that pretty for the pros). Not a lot of penetration on the back side, tried a edge to edge joint from both sides . It was solid. Around 50 amps.
Also ran some ok breads on 28 gauge at 5 amps (ya some burn throughs) . Had no material sizes in between. This is with scratch tig. and an amateur using it.
I am extremely pleased
I thank you greatly for this technique and your video (s).
Bill Fleming ,what filler did you use. ..4143 or 5356,thnx
Benjamin, You are correct... Helium does not conduct an arc very well and the dc+ process already requires a tight or close arc. Helium would cause both poor arc starts and arc wandering. thanks for the question... Mister Tig
I thought I could never weld aluminuim with my DC machine. I go try it tomorrow.
Thx Mr. Tig!!!
Thanks a million Mr. Tig! I thought that you absolutely had to use AC to weld aluminum unless you shell out for helium to weld with DC. Now I don't feel so cornered into trying to save up for an AC capable machine just yet.
I would DC TIG aluminum with an aluminum stick electrode as the flux will dual shield the metal. Of course there will be slag, but it's very easy to knock it off compared to the kind produced by 6013 rods (that slag was difficult to control and hard to break off the welds).
Sounds like a recipe for slag inclusion.
Very cool! Thought aluminum was not in my near future but this looks like it is with my DC only machine! Thanks Mr. Tig.
instead of scratching into your material that you're getting ready to weld use the filler rod put one end on the plate and touch the tungsten rod
Yeah until the rod sticks to the tungsten
and this is the situation im in.
thanks a lot for this vid. haven't seen anyone saying you can do DC plus Argon only.. so this was great.
Steve, You should be able to push and release the tungsten all the way thru your collet from the torch end. . Sometimes the tolerances are so tight that the paint on the tungsten actually prohibits good clearances. Give it a try and let me know... thanks Mister TIg
At 2:05 "You get a half a cleaning cycle" sounds like we're still thinking about AC. Here is all cleaning, all the time! I've watched this a few times, it's a rare take on a useful and forgotten method. I have renewed interest b/c it looks like I'm getting access to an old TIG power supply that can deliver over 300A and also have a spare water-cooler and some big Tungsten! (3/16 say). You can get up to 1/4".... Let's see what this can do! If it works, I'll name the demo after Mister TIG!
I just use aluminum brazing rod with a propane torch (yellow map gas) for simple repairs. I would guess a lot of farmers use this method also. You can buy the rod at tractor supply or online. It's way easier and portable.
I weld things out of lawn chair aluminum tubing. I have to try this and see if it can work any good. I have Miller Machine with variable AC cycle and usually do this on full clean cycle. Try going all the way to full clean cycle
This is so handy for me I live in a farming area like mostly farming or logging nothing else outside of government work but with the wheel lines I had to move the part to the shop to fix and these aren’t art work it’s about function and getting it done fast and cheap so fixing it with the engine drive machine really saves the day and gets me more work as a rig welder but I’m still perfecting the technique it’s not as easy as my ac machine back at the shop but I’m learning and getting better
i only use DC with helium on very thick aluminium to achieve vey deep penetration and then I finish With Argon AC. AC current is used to weld aluminum because its positive half cycle provides a cleaning action and its negative half cycle provides penetration. You don't get cleaning action on DC so its full of porosity
I'll give it a shot. It never fails for me and aluminum. It's always a pain, like .040" wall tube with a 3/8" thick bung that needs to be tapped.
hey mr tig , is there a recommended tungsten for this application. thnx.

one of the few videos on TIG with DCEP! thanks, can you please make a video for DCEP on steel? since I think the appearance of bead will be very cleaner on DCEP. true?
Thanks for the vid. The only thing that you left out was the approximate AMPs it took. Also, it looked like there was a TON of distortion!
just the normal amount of distortion for an uncontrolled joint. Aluminum moves about three times more than steel.
Nice, how many amps were you welding at? That machine was it set for TIG welding and reverse polarity or was it set for stick w/ reverse polarity?
I have a bathroom exhaust fan blade that has multiple cracks on the flat between a couple of the upright blades. I will be attempting this process to repair it and I will video that and send you the link once I post it on CZcams. Thank You for the continued knowledge! my Miller Multimatic 215 should do the job with a Furick Cup and gas lens system running straight Argon
Thank you mr. tig. I love learning new things like this! Have a happy holiday!
It didn't come up, but I think this is the original TIG method. The problem is that a majority of the power is being used by the electrode and not the work. This was hinted at here. You get maximum cleaning, poor control, low penetration , low efficiency. On the other hand, if you really have to do this, there are bigger electrodes and water-cooled torches too! I've heard that some people use this for very thin sheet.
the penetration is higher if you use helium
put your ground cable on positive and torch on negative
The wedge collets are bad ass all i use on dc
Very interesting. Thanks for the video I think I will use more than I thought initially.
I use 3/16 tungsten welding aluminum we weld from 320 too 500 all day
Mr. Tig in your brazing vs soldering video you omit to mention the
real difference between the two procedure
1. brazing is mostly kell welding, you did say that but it is not necessarily waterproof
2. soldering provides a waterproof connection by the capillary action I do not dot that you very well aware of this , ßo 5hat is just an omission
3. the third method could have been mentioned the silver brazing which is a solution between the two.
I am a subscriber and appreciate your videos and will keep watching, pls consider this as a constructive comment

Mr. Tig,
Thanks for the video first. Next can you give any pointers for keeping the arc going with this method. I get a puddle and then as I add filler, the arc dies.
Cheers,
I was using Helium, I also tried DCN Helium welding. It seems very difficult to keep the arc using Helium, any tips?
Good tip!!! And thanks for not having any killing the cat gitar music.
Thanks for the video Mr Tig!
What is the filler rod material that you've used?
First thanks for this video information! Question: can I Tig weld Aluminum with any (A/C) welder even a buzz box or it has to be (HF= High Frequency) only?
mr tig how many amps wher you using to weld with this set up
hakman239 that’s what I want to know
35-40 Amps probably.
Thank you got a maxstar 161
I keep coming back to this topic every year or so... I notice that there are WP-12 torches out there, and Tungsten electrodes up to 3/16" and even 1/4" which are expensive but do turn up. I have the electrodes but not the torch. So, the thinking here is to get a HUGE electrode in a water-cooled torch, and just DEAL with the inefficiency of this... and use the full output of say 250Amps on DCEP to weld thin sheet.
super thx for your Information. i go try it today. i love your channel
thank you Mr.Tig I will try it soon
PERFECT !!! PLEASE ELECTRODE IS + OR - ?
Thanks a lot mister tig! Have this vid a like 👍🏻
hi wyatt thanks for the video, have to ask a few questions, you say this is to be used in a pinch, prone to cracking? would preheat help? what are the settings (amps, rod and cfh) you used? any allow to be aware of?, sorry many questions :), thanks again. cheers. pete
Man I miss Mr.Tig !!!!!!
Steve, is there something in particular that you miss? Let us know what you want to see and Bob can get it done.
Bob is the best, really grown to enjoy his style and humor.
your a great teacher, Thank You !
Thanks tig daddy
Thanks for info had to buy a Arc welder just to do some cast welding :( and now i need to do some ali and was like i dont want to buy another machine :(
I tried this setup for thin aluminum tubing on an automotive project. And it did exactly what you had said in the video. But I have a hard time but welding aluminum tubing. Is this not good setup to but weld?
Thanks for the video, Just wanted to say once again that after the explanation in your email I am a firm believer in the new collet that you sent me!
Thanks. Good info. I have a Thermalarc 252i 3/1 that is just DC. I am getting a spool gun for aluminum but I will have to try this.
The spool gun will give you much better results unless you're in a pinch.
For repairs I'll use the spool gun but it's always good to have the ability to do what you got to do to get the job done. Right now all my aluminum repairs are done with my Miller blue star DC stick.
Wow that’s pro stuff!!! Thnx For helping
How about showing how you set up for DC pos
Hook up your torch to the + side on your machine, and the geound clamp to -
Thank you so very much. Very informative.
What setting is your your current, voltage, frequency, pulse, hot start parameters. My tip literally melts down completely into a large ball and the aluminium craters or burns through with current at 75 amp, frequency 100hz, pulse 2T.
with the dc set up cheers
How i can do that left tig or hf tig? More details plz
Thank you
Hey mr tig, does that mean I can tig weld aluminium with my dc inverter 180 amp caddy type welder?
John bennett in a pinch it is possible, but not the preferred way of doing it.
Weld.com thanks for the quick reply, I do have access to a ripper kemppi tig welder at work that I use for hf ac alloy tig welding but it is good to know that at home I can get away with my own welder for small patch up jobs, sorry for the follow up question but would I attach my torch to the - side of my welder just as I do for s/s tig work?? Cheers.
For this particular application you would be welding the opposite as your normal SS setup. Setup your machine for DC Electrode Positive. Torch is +, Ground is -
@@Welddotcom I just tried this and did not work. Tungsten just splattered like mig or flux welding
Jose Gonzalez were u using a thick 1/8th tungsten? I wanna try this myself lmk
I love your channel great information,
Never could get this to work my tungsten just turns red and my ball falls off using 1/8 i have tried dif amps and am using 100% argon i think im trying to weld to thick of material around 3/16 to 1/4
Wyatt:
What amperage and what size filler ? Why 1/2 cycle of cleaning I thought that the dc output was constant (capcitor smoothed)
I think this is a mis statement, since it's DC, there's no "Cycle". It's ALL cleaning!
Would using the pulse feature be beneficial for the tungsten?
Can use red tip
Mr.Tig, I have an Everlast 140st scratch tig machine . I'm interesting and welding some aluminium turbo inter cooler tubing using the technique shown in this video? Will this technique cause any damage to my machine and should I plan on trashing 1/8" tungsten to get the job done? Also one last question, if this method works for the aluminium tubing , should I setup a purge while welding it? Thank you.
to start i am not a welder... but i am a looking to buy a welder. also i will prob never weld aluminum. i will mainly be welding on my old f100, i used a lincoln 130t for the first half of the project. i now need a new welder so i was looking at dc inverter with tig/ stick welding. i know i will need to relearn how to weld but my question is would this be a better welder to buy vs buying another self feed? i want to be able to weld more than just sheet metal... maybe some frame work. and would i be able to do aluminum with a dc inverter
Hi Mr Tig,
I have an DC inverter machine,my question is, what colour of Tungsten should i use to weld aluminium
Hi Wyatt-thanks for another great video. I saw a previous vid where you recommended the wedge collet and I contacted Bonnie to find a supplier here in the UK-got them after 10 days. Only problem I have is the tungsten doesn't want to feed from the front of the torch,I have to take the back cap off each time. Is this normal? (1mm tungsten ) Cheers
Thanks for posting Mr Tig!! Will be great to try out for an odd repair when needed.
The guy didn't even specify a current but from elsewhere I read you shouldn't be using anything more than about 30 amps or so... anything more and the tungsten balls up badly. I guess for anything thicker you can just stick weld it. I mean let's face it, welding thin stuff is the real challenge here.
I heard you can do this also but have to use helium instead. What gas did you use?
Argon! It says in the intro. With Helium it's "Heliarc" welding, which has a separate video. There's no cleaning action with Helium, and it's different in other ways.
Did it work with lift tig
What is the diameter on a gargantuan tungsten electrode? 🙂
the easiest thing in the world is to weld aluminum, I have welded one and the same weld at least 100 times before it became airtight
Thanks for posting this ... Would using helium with this technique create arc starting issues greater than on dc- ?
If you have helium, use DC-
Random question (perhaps a silly one too lol)
Could one of the scratch start hand pieces with the gas valve be used with an AC ARC welder for welding Aluminium? It would be the coolest thing to weld Aluminium with an old buzz box! :-)
+joehunt1980 ..with AC you usually will need hi-frequency for aluminum or magnesium... you can buy an add-on arc-starter that will work...but by that time, you've spent enough to get a small AC/DC TIG.
intresting.. very useful info
I have a new Lincoln LE31MP (still in the box) and I want weld an antenna tower tilt / hinge base. maybe 20-24 inches in all. I’m in it for $900 +/- and it says stick, mig and tig but you need to buy more stuff 😠. the Lincoln folks said I need a spool gun and argon gas. Tractor Supply has a 40cu ft tank for $170 (I assume it’s full) and the spool gun is $350. do I need the extra items?
can i use any other gas ?
my welder has the gas and dc- together inside the machine.there is any solution for reverse polarity?
Hey i have a qeustion i do not know how to lith the torch when i apply my gas and try to get the job done i dont have a flame like all your videos show
i use a Kibani Tig/MMA Welding machine
What happens if you did this dcen
Well, it doesn't look good.. but damn if it didn't work! Thanks for the info, as always!
hola , me gustan buestros videos, pero no entiendo mucho el ingles, existe la posibilidad de que puedan traducir o colocar subtitulos en español, agradecido
I'm trying to join 2 x 1/16 aluminum plates together with dcep. I've got a 1/8 2% ceriated tungsten, my piece is very clean. The tungsten is ground lengthwise. I've got the machine at 35amps with and a pedal. At lower amps the arc does not want to settle at all and when i bring it up to the 35, it focuses, but then melts through the edge plate all together. Help!
Looks like he has positive ground, hence his statement (with little detail) set the machine for DC positive.
No but you might want to have yourself examined.
Can i use a 3/32 tungsten for this?
Im curious on what the amperage that you were using?
im seeing online that in DCEP that you can only run about 55 Amps tops on a 1/8 tungsten.
so if i was in a pinch and needed to use my dc machine to fix something where do i start?
Is this with straight helium as well ? Or argon ?
hi ..
I got a Dc Tig200P and I really want to weld aluminum and I got straight argon. .Do you think I can refill my cylinder head and bring it back to life again
what size tungsten is that? i have 2.4mm rods, they look tiny in front of this one.
How pure this argon is 4.6, 4.8 or 5.0
With the aluminum. What amperage we you using. Thanks
and coupd you do this with a 1.6mm electrode

CAN I WELD THE ALUMINUM WITH MILLER DIALARC 250V AC DC ?STICK USING SCRACH 26 TIG TORCH?NO HIGH FREQUENCIES??
What is that pink cap around ur welder ?
Last time I tried to dcep tig my tungsten just smoked up.
What amperage did you use?
inverter machine can aluminium welding
Nick, Let us know which machine you have and we will try to help you. A photo of the face of your machine will help.. thanks Mister Tig
what was the amperage setting?
What tungsten are you using?
