*1. The listed capacities of fuses and breakers (or leakage protectors) are only for reference.
*2. When the machine is working at the places where are moist or on the iron plate or stand, please be sure to
install leakage protector.
Note:
please follow the regulations listed below to avoid any damage of parts, unstable arc and overheat or damage of
the machine.
● The fluctuation range of input: the allowable rated input voltage is 304V ~ 456V.
● When the generator is used, the rated input capacity should be two times of cutting power source or higher. The
generator should be equipped with compensating coils.
● The wiring of input side: please equip each cutting power source with one fuse switch or non-fuse breaker (or
leakage breaker) of which capacity complies with the rated one of the cutting power source.
● Please select the proper breaker (or leakage breaker) which is applicable to electric distribution, such as cutting,
electric motor or transformer.
