Which gas

[Wild Hare]

I just purchased a mig welder w/o a tank. I'll be welding mostly sheet steel and possibly some heavier steel. Should I go with a CO2/Argon mix like C25 or go with straight Argon?

[Knowledgeworker]

For mild steel, C25 is recommended (CO2/Argon mix 25/75)

Thanks for the response. I asked because someone had indicated I should use straight Argon. He has since corrected himself.:rolleyes:

Your quite welcome. I use 100% argon for welding aluminum.

Always trying to help. I may not always be right, but I'm never wrong. (My employees told me this before I retired):D
