GENERAL DESCRIPTION

The Commander 400 is a diesel engine driven welding
power source. The machine uses a brushless asyn-
chronous alternating current generator for DC stick
electrode welding and for 120/240 VAC auxiliary
standby power. As a generator it can supply up to
10,000 watts of 120/240 volt AC power. As a welder it
provides up to 400 amps of DC constant current output
in six slope-controlled ranges. In addition a seventh
general purpose welding range provides up to 575
amps of constant current welding output.
The engine is a 44.2 Hp (33kw), 3-cylinder air/oil
cooled diesel made by Deutz. This naturally aspirated,
4 cycle engine features direct injection, a Bosch in-line
injection pump and a Bosch mechanical governor.
This machine is controlled by a high quality microcon-
troller. The microcontroller provides high speed control
of the weld process as well as the engine protection
features.
