Forgive my ignorance, I'm not really a very skilled or experienced welder...but at the shop there is a welder they call a "MIG" welder and it has a spool of wire in it's innards. When I squeeze the trigger on the grip, wire comes out at the tip and is turned into molten metal along with part of my workpiece in a blazing display of electric power (especially if I'm not careful it burns holes in my workpiece or welds it to the table...).
What kind of welder izzat?
That is a MIG but the wire melts in the arc not in the tip.
