sheild gas for weldin aluminum?

you can, but DANG that is going to be expensive. i also dont see the problem with using 100% argon. its what i use daily on aluminum usually more than 3/8 thick. sometimes 2 inch thick, and dont have problems with penetration.welder_one
nothing fancy, just a few hot glue guns for metal

I use straight Argon for both MIG and TIG. Thickest I have welded aluminum is 1/2" and argon works great on all that I've used it for.Scott

It can be confusing at first but after awhile it isn't all that big of a deal...just keep reading and asking questions.
