N.B.
1) Turn off the switch of the switch box while connecting cable. Provide a switch box for every
welder and use a specified fuse.
2) Power supply cable should be 14 mm
3) If an engine generator is used, it should be provided with an inverter of capacity from three to
five times of that of the welder or with compensating winding for thyristor equipment.
4) When using single phase, connect to "U" and "V" terminals. And keep the output current
below 180 A.
Grounding
①. Protection against electric shock caused by degraded insulation of welder Ground the case to
prevent electric shocks and malfunctioning of equipment caused by high frequency waves gen-
erated from inert welder controller.
②Daily checking of grounding conductor perform daily check of grounding conductor. Confirm whether it
is disconnected or broken. If it is disconnected, or broken, reconnect it. The switch of the switch box
must be turned off before reconnecting.
