CAUTION:
INCORRECT INPUT POWER can damage this welding power source. Phase to ground
voltage shall not 10% of rated input voltage.
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 available.

1 If a circuit breaker is used in place of af a fuse, choose a circuit breaker with time-current curves comparable to the recommended 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).
4 Conductor data in this section specifies conductor size (excluding flexible cord or cable) between the panelboard and the equipment per NEC Table
310.16. If a flexible cord or cable is used, minimum conductor size may increase. See NEC Table 400.5(A) for flexible cord and cable requirements.
