GENERAL DESCRIPTION

The DX300e (CE) is a diesel engine powered DC
multi-process welding power source and AC power
generator. The engine drives a generator that supplies
three phase power for the DC welding circuit and
three phase and single phase power for the AC auxil-
iary outlets. The DC welding control system uses state
of the art Chopper Technology (CT
welding performance.

FOR AUXILIARY POWER:

Start the engine and set the IDLER control switch to
the desired operating mode. Full power is available
regardless of the welding control settings providing no
welding current is being drawn.

BREAK-IN PERIOD
Any engine will use a small amount of oil during its
"break-in" period. For the diesel engine on the
DX300e (CE), break-in is about 50 running hours.
Check the oil every four hours during break-in.
Change the oil after the first 50 hours of operation,
every 100 hours thereafter. Change the oil filter at the
second oil change.
During break-in, subject the DX300e (CE) to mod-
erate loads. Avoid long periods running at idle.
Before stopping the engine, remove all loads and
allow the engine to cool several minutes.
