CABLE CONNECTIONS

Connection to the 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 fit an alternative plug type, ensure installation is completed
by an authorised electrician.
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 machine can also be used with a generator. The minimum power for the generator is
4.5 kVA, and the recommended power 7.0 kVA in order for the machine to be used at
maximum capacity.
Electrode holder
Connect the welding cable to the power source. Normally, the welding cable with electrode
holder is connected to the positive terminal (electrode +).
Earth return
Connect the earth return cable to the power source. Normally, the earth return cable and
clamp is connected to the negative terminal ( – ). Clean the workpiece surface and fix the
earth return cable clamp to the work piece in order to create a welding circuit.
