Thread: Need A Tig Answer Please

100% argon only, you don't need mixes it just cost more, only other gas you might need is if you are tigging heavy aluminum and need more heat so you would use helium

Ahh, But str8 argon works for aluminum also, even 1/2" aluminum. I just did some 1/2" aluminum welding a few days ago.

Dang!! This is almost a year old.

So, Don, how did it all work out? Did you go with straight argon?

In my learning experience, we were taught the following: straight argon for general TIG work, and a helium mix for some special stuff like heavy aluminum, if you wanted; argon-co2 mix on MIG, except for some special cases. I think it has to do with the composition of the filler metal, and the characteristics of, and the way the arc reacts with the base metal and the filler.

Don went on to do the weld, got married had 3 children and wrote a best seller entitled ''1001 uses for argon''. He stated the book was a gas to write, but the royalty checks "are gone'.

LOL, he,he,he.....

You forgot about my ill-fated run for the Presidency and that little "incident" with Paris Hilton. .

We finally went with an argon mix. He won't be doing any aluminum in the forseeable future, so we didn't need pure argon. In fact, he has only played with the tig a few times so far, although he did tig the front shock tubes on his Brothers T.
