CAUTION:
Y
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
Input Voltage
Input Amperes At Rated Output
Max Recommended Standard Fuse Rating In Amperes
Min Input Conductor Size In AWG/Kcmil
Max Recommended Input Conductor Length In Feet (Meters)
Min Grounding Conductor Size In AWG/Kcmil

1 Consult factory for circuit breaker applications.
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).
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.
