        why’s my Miller Maxstar 161 leaving porous welds with 0.035-inch 4043 wire and 20 CFH argon? welds look bad, any ideas?

          Check for gas leaks on your Miller Maxstar 161, use 25 CFH argon, fixes porosity.

            clean aluminum with alcohol, Dirty metal causes porosity, use fresh wire for your Miller.
