GENERAL DESCRIPTION
TheSAE-300
®
HEisaheavyduty,enginedriven,DC
arc welding power source, capable of providing con-
stantcurrentoutputforstickweldingorDCTIGweld-
ing. This welder is wound with all copper coils, rated
at 300 amps/32 Volts, and provides other Classic
®
featuressuchasimproveddoorlatchesandstainless
hinges.WiththeadditionoftheoptionalK3964-1Wire
Feed Module™, the SAE-300
®
HE will provide con-
stant voltage output for running the LN-7, LN-23P, or
LN-25wirefeeders.(TheWireFeedModuleisfactory
installed on the K3201-2). The optional K924-5
Remote Control Kit, provides a remote control rheo-
stat for remote fine current and open circuit voltage
adjustment.SeeSectionCfordescription.
The SAE-300
®
HE has an Electronic Engine
Protection System. In the event of sudden low oil
pressure or high coolant temperature, the engine
immediately shuts down. The SAE-300
®
HE has a
current range of 40-350 DC amps with output ratings
asfollows:
These units are also capable of providing 3 KVA of
120/240voltsof60cycleACauxiliarypower.

DESIGN FEATURES
Control Panel
The welder controls consist of a Reactor and a “Fine
Current Adjustment” rheostat located on the upper
control panel at the exciter end of the machine. The
lower control panel welder is equipped with a “Start”
button, an “Ignition” switch, an “Idler” control switch,
anda“GlowPlug”buttonforeasiercoldweatherstart-
