[TheForge] Welding advice needed pronto

Sat Feb 26 00:03:38 EST 2005

Bill, Steel mix is a mig gas that is 12%C02 and 88% Argon.   The 75/25 gas
is 75% argon and 25% CO2.

Argon makes things flow out and is heavier than CO2, but the C0 2 in the gas
mix makes the wire burn hotter and give better penetration to the weld.

(in the case of dual shield wires like I often use, the heavier 25% amount
of C02 not only yields penetration, but also cools the torch head).
