GENERAL DESCRIPTION
The GX 300 is a gasoline engine powered DC multi-
process welding power source and 120 / 240 volt AC
power generator. The engine drives a generator that
supplies three phase power for the DC welding circuit
and single phase power for the AC auxiliary outlets.
The DC welding control system uses state of the art
Chopper Technology (CT tm) for superior welding per-
formance.
DESIGN FEATURES

Start the engine and set the IDLER control switch to
the desired operating mode. Full power is available
