2.6 Connecting cable connections
Connection to mains
The machine is equipped with a 3 m long supply voltage cable and plug. Connect the supply
voltage cable to the mains. The mains supply cable and electrical plug are already installed to
the machine. Should you need to t an alternative plug type, ensure installation is completed
by an authorised electrician.
NOTE! The fuse size needed is 16 A delayed.
If you use an extension cable, its cross-sectional area should be at least as large as the
machines supply cable (3 x 1.5 mm²). It is recommended to use 3 x 2.5 mm² extension cable.
The maximum length for the extension cable is 100 meters.
The minimum power of a single-phase machine generator must be 5.6 kVA. The
recommended power is 8.0 kVA for using the machine at maximum power.
Earthing cable
Connect the earthing cable to the negative pole in MMA welding, and to the positive pole in
TIG welding.
Before you start welding, clean the work piece surface and x the earth return clamp to the
work piece in order to create a closed and interference free welding circuit.
Welding torch (TIG)
The welding torch is used to supply shielding gas and electrical arc energy to the weld piece.
When you press the welding torch switch, the shielding gas begins to ow and the arc is
established. The TIG torch is connected to the negative pole.
