3-5. Electrical Service Guide

YCAUTION: INCORRECT INPUT POWER can damage this welding power source. This welding pow- er source requires a CONTINUOUS supply of 60 Hz (+10%) power at +10% of rated input voltage. Do not use a generator with automatic idle device (that idles engine when no load is sensed) to supply input power to this welding power source.

NOTE

Actual input voltage should not exceed ± 10% of indicated required input voltage. If actual input voltage is outside of this range, output may not be available.
