The Miller 212 (my best machine arguably) is easily switched with lugs
by the wire feed inside the cabinet. Nothing else changes when you swap
the cables. Always fires the associated solenoid when you pull the
trigger on one of the guns. I expect they figured most folks would only
run GMAW, and never FCAW with it, but the capability is there.
I ran FCAW for years because GMAW just didn't work on my steel stinger.
Since I'm not a real welder or even a real fabricator it took me years
before I discovered the problem. The gas diffuser in the stinger had no
holes. (It came that way directly from Miller.) I did have a gas
bottle sitting there, but it went many years without even cracking the
P.S. I find (maybe its due to grater experience with it) that FCAW is
much easier for out of position welding. Even overhead.
P.P.S. When I posted pictures of the gasless gas diffuser on Miller's
web forums they sent me a whole box of consumables including a couple
proper gas diffusers WITH HOLES.
