I did a search but didn't find much. What gas are you using for your MIG welder? 100% CO2, CO2/argon, or 100% Argon?

FWIW, the gas mix Argon and CO2 reasoning is 75%/25% because Argon excels with purity of the weld and the CO2 excels with the penetration of the weld. Aluminum needs purity so Argon&Helium are the ideal gases. Steel isn't as picky and benefits from the CO2 mix for strength.
Cheers, Don. |
