DESIGN FEATURES
Control Panel
The welder controls consist of a five step current selector switch
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.
Voltmeter & Ammeter
- Easy to read analog meter for volts &
amps located on the upper control panel (only on code 12459)
All Copper Windings
- For long life and dependable operation.
Engine Idler
- The SA-400I
®
is equipped with an electronic auto-
matic 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
connected 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 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 receptacle.
