I am welder by trade my favorite is stick the mig is fast tig is nice and clean i have a miller 225 ,chemtron ac/dc tig and a miller 250 deisel portable .What gas does everybody use with their migs?
the most common gas used on mild steel with mig is 75% argon and 25% co2 alot of manufacturing shops use strait co2 because its alittle cheaper but the 75/25 runs a little cleaner some people also use a 95/5 becouse it burns a little hotter but its more expensive and not all welding shops stock it
