3.3 CABLE CONNECTIONS

Connection to the mains

The machine is equipped with power supply cable and plug. Connect the supply
voltage cable to the mains. NOTE! The fuse size needed 16A delayed.
If you use an extension cord, its cross-sectional area should be at least as large as the
power supply cable's (3 x 2.5 mm
50m.
The machine can also be used with a generator. The minimum power for the generator
is 5.5 kVA. And the recommended power 8.0 kVA in order for the machine to be used
at maximum capacity.
Earth
The earth cable is already connected to the machine. Clean the workpiece surface and
fix the earth cable clamp to the piece in order to create a closed and interference-free
circuit needed for welding.
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 gun neck can be rotated 360° .When turning the neck, always makes 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. Thickness of the welded sheet and
welding power define the flow rate of the shielding gas.
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.
