CAUTION:
Y INCORRECT INPUT POWER can damage this welding power source. This welding power
source requires a CONTINUOUS supply of input power at rated frequency(+10%) and voltage (+10%).
Phase to ground voltage shall not exceed +10% of rated input voltage. Do not use a generator with auto-
matic idle device (that idles engine when no load is sensed) to supply input power to this welding power
source.

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).
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.
