SPOT ;
DEFINITIONS :
MIG 2 T: in this function the arc start when the wire
goes in contact with the piece. When you press the
torch button the wire start come out and it stops
when you leave the button
MIG 4T : when you press the torch button the gas
comes out ( pre gas ). When you leave the button
the wire start come out, and goes in contact with
