During welding, wire stickout (tip to work distance)
should be approximately 5/16 in. Poor fit up will

less, Argon-C0 2 mixtures may offer better arc
characteristics than C0 2. Use only welding grade
C0 2 gas at a flow of 15-20 cubic feet per hour.

GMA Spool-On Gun.
Remember! You do not have a flux to purge the
deposited molten metal; only a shielding gas prevents
the atmosphere from coming in contact with the arc
stream. Any moisture, dirt, or oil on the base material,
welding wire, or feed rolls will cause a defective weld.
