10. Simultaneous Use of Welding and Generating
■
The Circuit Breaker has activated due to overload
Caution: Injuries
•
Be sure to turn the power switch "OFF" in the load when turning the circuit
breaker to "ON" again, when the circuit breaker has activated.
When the electric supply exceeds the rated output (overload), the circuit breaker
activates to trip off in order to shut down the circuit. When the load operation stops
during operation, check the circuit breakers (3-P and 1-P).
In the case the 3-P breaker trips, the current leakage breaker lamp should have
turned to OFF. If the lamp remains ON, refer to No.5-5 Earth Leakage Relay.
When any breaker has tripped, restore the circuit breaker as per the following
procedure.
1) Turn OFF all the power switches in the loads.
2) Turn (Push) down the circuit breakers (3-P and 1-P) to "OFF" once. And then
turn (push) up the circuit breakers to "ON".
<Note>
•
Take care for overload, referring to "9-2 Output Limitation".
•
When the output selector switch is positioned to Eco and AC power is used, the
3-P circuit breaker trips off to shut down the circuit. Stop using AC power and
follow the above procedure to restore the circuit breaker
The circuit breakers (3-P and 1-P) react on the AC power supply circuit only. In the
simultaneous use of welding and generating, there sometimes happens overload to
the engine. Refer to the following table and limit the AC power use.

* In order to secure stable AC output, the output selector switch should be
positioned to DUAL in operation as long as possible.
<Note>
•
The simultaneous use of Eco welding and AC power is NOT available.
•
Avoid the simultaneous use in the case high quality result in welding is required
