Notice:
□ Please unpack and take off the plastic sheet before using.
□ Make sure that turn off the switch box before connect the cables.
□ Attach a switch with fuse of specified capacity or no-fuse breaker (or leakage breaker) to the switch box
for each welding source.
□ Use the cable which is more than 10mm

if it is more than 10m.
□ If use the dynamo, then its facility is more twice than that of power source.
