A-2 INSTALLATION
SAE-300 ® HE
A-2
GENERAL DESCRIPTION
The SAE-300 ® HE is a heavy duty, engine driven, DC
arc welding power source, capable of providing con-
stant current output for stick welding or DC TIG weld-
ing. This welder is wound with all copper coils, rated
at 300 amps/32 Volts, and provides other Classic
®
features such as improved door latches and stainless
hinges. With the addition of the optional K3964-1 Wire
Feed Module™, the SAE-300 ® HE will provide con-
stant voltage output for running the LN-7, LN-23P, or
LN-25 wire feeders. (The Wire Feed Module is factory
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. See Section C for description.
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
as follows:
These units are also capable of providing 3 KVA of
120/240 volts of 60 cycle AC auxiliary power.
The SAE-300 ® HE uses the Kubota D1503-M industri-
al water-cooled diesel engine.
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,
and a “Glow Plug” button for easier cold weather start-
ing.
The lower control panel also contains an engine tem-
perature gauge, a battery charging fault indicator, an
oil pressure gauge, a fuel / hour / LED indicator
gauge, temperature gauge, for auxiliary power con-
sists of one 20 amp, 120VAC (5-20R) duplex recepta-
cle with GFCI protection and one 15 amp, 240VAC (6-
15R) receptacle, protected by 2 pole, 15 Amp break-
er.
All Copper Windings - For long life and dependable
operation.
Engine Idler - The SAE-300 ® HE is equipped with an
electronic automatic engine idler. It automatically
increases and decreases engine speed when starting
and stopping welding or using auxiliary power.
A built-in time delay permits changing electrodes
before the engine slows to its low idle speed.
The “Idler” control switch on the panel locks the idler
in high idle position when desired.
Auxiliary Power - 3.0 KVA of nominal 120/240V,
60Hz, AC. Output voltage is maintained within ± 10%
at all loads up to rated capacity. (See Optional
Features Section C for Power Plug Kit.)
GFCI - Protects the 20 amp, 120V duplex receptacle.
See the Maintenance Section for detailed informa-
tion on testing and resetting of the GFCI.
120 V DUPLEX RECEPTACLE AND GFCI
A GFCI protects the 120V auxiliary power
receptacle.
A GFCI (Ground Fault Circuit Interrupter) is a device to
protect against electric shock should a piece of defective
equipment connected to it develop a ground fault. If this
situation should occur, the GFCI will trip, removing volt-
age from the output of the receptacle. If a GFCI is tripped
see the MAINTENANCE section for detailed information
on testing and resetting it. A GFCI should be properly
tested at least once every month.
The 120 V auxiliary power receptacle should only be
used with three wire grounded type plugs or approved
double insulated tools with two wire plugs. The current
rating of any plug used with the system must be at least
equal to the current capacity of the associated recepta-
cle.
