400V Supply
For wiring to a 400V supply, the colour codes of the wires are as follows:
Green and Yellow .......... Earth
Blue .......... Live (L1)
Brown .......... Live (L2)
DANGER - ELECTRIC SHOCK CAN BE FATAL.
A person qualified in first aid should always be present in the working area.
If person is unconscious and electric shock is suspected, do not touch the person if
he or she is in contact with the welder or cables. Disconnect the welder from the
power source and then use First Aid.

Dual Supply
For machines capable of operating on 110/230V and 230/400V, the voltage
selector is designed so that it can select only one voltage. In order to change
voltages on earlier models, it is necessary to change the switch gate as follows:
1.
With the voltage selector knob in the OFF position, slacken the knobs’ grub
screw and remove the knob, to reveal a circular plate.
2.
Remove the two screws securing the plate, then reverse the plate.
3.
Replace the two plate securing screws followed by the selector knob.
This knob can now be moved to either the 230 or 110/400V position, depending
upon the position of the plate.
On later models the position of the screw,
arrowed in the illustration opposite will determine
the voltage selection.
With the screw in position 1, the switch may be
turned from O - OFF to 230V.
With the screw in position 2, the switch may be
turned from O - OFF to 400V.
110V Supply
A suitably approved 110V connector is required and should be connected to a
suitably protected circuit in accordance with the instructions below.
IMPORTANT:
1.
On no account must a 230V, 13amp (BS1363) plug be fitted to these
machines.
2.
If a 110V transformer is used, ensure it has a rated capacity sufficient
to take the load of this machine...check the data plate.
