i picked up a MIG welder a while back that i have been using, its a non gas, uses flux cored wire, i think its a campbell house but i don't remember off the top of my head. Question is, is there any other wire that i can use with this welder (non flux core, or will the welds get contaminated?), is there any way to make the welds cleaner like less splatter (like a different thickness of wire or something
