4-5. Electrical Service Guide

NOTICE − INCORRECT INPUT POWER can damage this welding power source. This welding power source requires a CONTINUOUS supply of input power at rated frequency(+10%) and voltage (+10%). Phase to ground voltage shall not exceed +10% of rated input voltage. Do not use a genera- tor with automatic idle device (that idles engine when no load is sensed) to supply input power to this welding power source.

NOTICE − Actual input voltage should not be 10% less than minimum and/or 10% more than maximum input voltages listed in table. If actual input voltage is outside this range, output may not be be available.

Failure to follow these electrical service guide recommendations could create an electric shock or fire hazard. These recommenda- tions are for a dedicated branch circuit sized for the rated output and duty cycle of the welding power source.
