Lincoln Electric IM10155 SAE-300 HE - Manual (Page 9)

A-2
INSTALLATION SAE-300 ® HE
GENERAL DESCRIPTION
The SAE-300 ® HE is a heavy duty, engine driven, DC arc welding
power source, capable of providing constant current output for
stick welding or DC TIG welding. 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 constant voltage output
for running the LN-7, LN-23P, or LN-25 wire feeders. The
optional K924-5 Remote Control Kit, provides a remote control
rheostat for remote fine current and open circuit voltage adjust-
ment. 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 tempera-
ture, the engine immediately shuts down. The SAE-300
® HE has
a current range of 40-350 DC amps with output ratings as fol-
lows:
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 Perkins 403F-15T Turbo Charge
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
starting.
The lower control panel also contains an engine temperature gauge,
a battery charging fault indicator, an oil pressure gauge, a fuel /
hour / LED indicator gauge, temperature gauge, for auxiliary power
consists of one 20 amp, 120VAC (5-20R) duplex receptacle with
GFCI protection and one 15 amp, 240VAC (6-15R) receptacle,
protected by 2 pole, 15 Amp breaker.
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 auxil-
iary 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 information 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 con-
nected to it develop a ground fault. If this situation should occur, the
GFCI will trip, removing voltage from the output of the receptacle. If
a GFCI is tripped see the MAINTENANCE section for detailed infor-
mation 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
receptacle. 250A @ 30V
