3-10. Connecting To 1-Phase Engine Generator w/230 Volt Output
Installation must meet all National and Local Codes − have only qualified persons make this installation.
.
Obtain a 230 volt plug that matches the receptacle on the engine generator. Install the plug on the cord of the welding power source according
to the plug manufacturer’s instructions.
Generator Requirements

Engine generator must provide the correct input amperage (see Section 3-8).

Peak voltage must be less than 423 volts AC

RMS voltage must be greater than 180 volts AC.

Frequency must be between 50 and 60 Hz
NOTICE − Make sure welding power source is off during engine generator start-up. Do not turn on the welding power source until the generator has
reached normal operating speed.
