When using at a construction site or in a humid place or on an iron plate or steel frame, a
leakage breaker should be also installer.
…………………………………………………………………………………………………………………
For safe use and operation, observe the following. Otherwise, the parts may he broken, arc
may become unstable, or devices may be burnt out.
Fluctuation of the supply voltage An allowable range is a rated input voltage±10%.
When using the engine generator: use the generator which has a capacity twice larger
than the rated input of the welding source and is
provided with compensating winding.
Wiring on the input side: Attach a switch with fuse of specified capacity or no-fuse
Breaker (or leakage breaker) to the switch box for each
welding source.
When using the no-fuse breaker or leakage breaker, select those for the welding machine
or motor or transformer.
This machine has input power frequency select switch. Please confirm the correct position
of the switch. (Refer to Pages 22,23 and 25 )
This machine should be used in combination with the specified wire feeder.
