Tig Welding Aluminum with helium added to the argon works a lot better for thick aluminum and can sometimes get you over the hump if you dont have enough amperage.. It is the quickest, cheapest, and easiest way to take a quantum leap in your ability to tig weld aluminum. If you were wondering how to tig weld aluminum better, especially aluminum that is 1/8 inch thick or thicker, this video on tig welding aluminum is for you.

@GameFishermen I had a dynasty blow up on me...the compasitor blew and it was like a hand grenade going off...paper everywhere..shit in my pants

Helium has a much higher thermal conductivity than straight argon. Argon is a dense gas that gives good shielding at low flow rates. Also,argon-CO2 mixes are primarily for mild steel MIG welding using short-circiut transfer. I have run MIG spray arc using AG-2 (98%argon,2% oxygen). 5% or less oxygen is safe from porosity.I know it doesn't make sense but it's true.I've been a welder for 18 years.

I'll agree that the dynasty 200 is a good machine, but its begun to die on me lately. I had a 21ft skid loader trailer come into my work with a broken storage box in the front, and needed a 4x6 piece of 1/8in 5052 diamond plate welded to the back on the loading ramp. And for some reason it won't puddle for like 3-4 seconds on 200amps maxed out.

What about the 20lb throwaway helium tanks for ballons?
think its clean enough?
100lb tank of helium would last me forever!
Also my gas suplier wont take any new orders for Helium says theres a shortage.
what preasure of argon & helium?

@Helpmefly it's still about 2-5 times as expensive as argon, depending on supply/demand. He is cheaper in the US because we have large reserves of natural gas, and a lot of our gas wells have a higher-than normal percentage of helium. Also, it's questionable to be using He for trivial things like welding or balloons, since it's a non-renewable resource. There are some technical and scientific applications which simply won't work without helium, most important being MRI machines.

1) NO! Adding CO2 to your shield gas will result in slagging both the aluminum and your electrode to a lesser extent. Al is pretty reactive towards CO2. You might be able to use it for DC welding steels in a pinch. However 15%CO2 is an excellent all-purpose mix for MIG
2)No. MIG welding power supplies are of the "Constant voltage"(CV) type. TIG and stick need "constant current" power supplies (CC). Trying to TIG with CV would make starting and arc control almost impossible.

can you meld metal with a tig with Welmix 15? 85% argon 15% co2?
and can you use a tig tool on a migmag machine?

I like the use of the heat sheild mesh on your torch hand.. great idea.
I use a mix of argon/helium through a company in Canada called "blueshield" there are 3 mixes. 1=25% helium to 75% argon
2=50% of each (my favorite for sure)
3=75% helium and 25% argon (super hot)
this is a great way to teach those who can or want to weld. Thanks for the tips and tricks.. your never too old to learn.
