I wondered what straight argon is like in a mig on steel?
I have just run out of argon and will save >£50 a year[i hope] if I just get a cylinder of argon and take my argoshield cyl' back.. I changed to small cylinders a few years ago they didn't save me anything as the filling costs negate any savings, but if i was to use argon in both mig and tig I might save..
I seem to recall using argon in the mig a long time ago, and also seem to recall better penetration with argoshield?
