Y CAUTION: 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.
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.

2 “Time-Delay” fuses are UL class “RK5” .
3 “Normal Operating” (general purpose - no intentional delay) fuses are UL class “K5” (up to and including 60 amp), and UL class “H” ( 65 amp and
above).
