MinarcMig™ Adaptive 180
Welding gun
The welding gun is already connected to the machine. The welding gun leads
the filler wire, shielding gas and electric current to the weld. When you press
the welding gun trigger, shielding gas flow and wire feed begin. The arc ignites,
when the filler wire touches the welded piece.
The factory-installed wire guide in the welding gun is best suited for steel
wire welding. However, it can temporarily be used for stainless steel wire
and aluminium wire welding. Then, however, friction is greater and thus the
wire feed may tangle. If you mainly use stainless steel or aluminium wire, we
en
recommend you change the wire guide to a plastic wire guide.
The gun neck can be rotated 360°. When turning the neck, always make
sure that the neck is twisted almost all the way to the bottom. This prevents
damaging and overheating the neck.
NOTE! If you use other than 0.8 mm diameter filler wire, change the
welding gun contact tip to match the wire thickness.
shielding gas
The shielding gas used for steel wires is carbon dioxide or a mixture of argon
and carbon dioxide which replaces air in the arc's area. Shielding gas for
stainless steel wires is a mixture of argon and carbon dioxide (2%) and argon
for aluminium wires. Thickness of the welded sheet and welding power define
the flow rate of the shielding gas.
The machine is delivered with a 4.5 m long shielding gas hose. Connect the
bayonet socket of the shielding gas hose to the machine's hose connector and
the hose connector end to the gas bottle's control valve.
