INSTALLATION
ELECTRICAL CONNECTION
WARNING! Ensure proper AC earth grounding of the Gullco welding positioner and all auxiliary
equipment (where applicable), before applying power. Failure to do so may
invalidate the Gullco Warranty.
WARNING! Before connecting the welding positioner to a power source (receptacle, outlet, etc.,)
be sure that the voltage supplied is the same as that specified on the nameplate of
the positioner. If in doubt, DO NOT PLUG IN THE WELDING POSITIONER. Copies
of the possible nameplates are shown below:
As the colours of the wires in the mains lead of this equipment may not correspond with the
coloured markings identifying the terminals in your plug, proceed as follows:

The Green & Yellow or Green wire must be connected to the terminal in the plug which is
allocated for “Earth” / “Ground”.

The Blue or White wire must be connected to the terminal that is allocated for “Neutral”.

The Brown or Black wire must be connected to the terminal that is allocated for “Live”.
230V Equipment must be installed in accordance with CEC, NEC or other applicable electrical
code.
WARNING! Ensure that the weld ground is properly attached to the ground bracket on the
positioner. A poor welding ground circuit will cause the weld ground to pass through
the positioner, causing damage to the motor control, cables, drive system and the
main spindle bearings. This will invalidate the Gullco warranty.
