mOunting OF mig welding gun

In order to ensure trouble-free welding check in operation instructions of gun used by you
that wire guide tube and contact tip of gun are according to manufacturer's recommendation
suitable to be used for wire feed diameter and type in question. Too tight a wire guide tube
might cause for wire feeder unit a bigger stress than normally as well as disturbances in wire
feed.
Screw snap connector of gun tight that there won't come any voltage losses on connecting
surface. Loose connection will heat gun and wire feeder unit. When you are using liquid-
cooled gun, mount water hoses according to ASSEMBLY OF KEMPOWELD EQUIPMENT.
