MIG machines can also use a type of filler wire called flux core which
needs no inert gas to keep the puddle from oxidizing. this wire is
great for welding on dirty/greasy carbon steel and gets good
penetration although it does spatter quite a bit. it runs very smooth
in all positions. it is very forgiving in tough situations.

I saw a MIG welder at Schucks for $179.99 or so, he said it needed no
gas, I think it used innershield, isn't the "G" in MIG for "gas"? The
gun had a nozzle on it. I have been out of the welding loop for a few
years so I didn't know if this was a good buy, also if it needed an
inert as tank with it.
Maybe they should call it a MI welder?
