CAUTION:
INCORRECT INPUT POWER can damage this welding power source. This welding
power source requires a CONTINUOUS supply of 50/60 Hz 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 cannot exceed
±
10% of indicated required input voltage. If
actual input voltage is outside of this range, no output is available.

1 Choose a circuit breaker with time-current curves comparable to a Time Delay Fuse.
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).
Caution: Failure to follow these fuse and circuit breaker recommendations could create an electric shock or fire hazard.
