I have a MIG welder and would like the option to weld some stainless as well as mild steel. i have 2 questions though.
1. will stainless wire be ok to weld mild or would i be best to swap the wire back to mild?
2. The second and most important question. will argoshield light be ok for stainless? on weld equip website on the stainless welding page, it says "Use with Argon/CO2 mix shielding gas" but on the BOC website argoshield light page "Please note:
Should not be used for welding stainless steel or nickel alloys because carbon from the shielding gas will be introduced into the weld (carbon pick-up). " and then the mig welding tutorial on here says "Shielding gasses for MIG
"The best gas for MIG welding stainless is 97.5% Argon +2.5% CO2. Previously an Argon/Oxygen mix was widely used, but this doesn't give as smooth a finish as the Argon/CO2 mix.
For mild steel welding 80% Argon plus 20% CO2 is common, with 95% Argon plus 5% CO2 often used for thin sections, but even 5% CO2 is too oxidising for stainless and will leave the weld looking black. "
From what i understand, argoshield light contains 93% argon, 5% CO2, 2% oxygeon.
please help, dont want to get a bottle of gas that is unsuitable.
