OPERATION
B-2
FOR AUXILIARY POWER
• 12,000 watts of 120/240 VAC, 60Hz auxiliary power.
• Power for tools, 120/240 VAC lights, electric pumps
and for standby emergency power.
• Drive a 5 HP motor (provided it is started under no
load).
• Two 20 amp 120 VAC duplex receptacles for up to 40
amps of 120 VAC power.
• One 50 amp, 120/240 VAC dual voltage receptacle for
up to 50 amps of 240 VAC, and up to 50 amps per
side to separate branch circuits (not in parallel) of 120
VAC single phase auxiliary power. Allows easy con-
nection to premises wiring.
• Weld and AC auxiliary power at the same time (with-
in machine total capacity).
OTHER FEATURES
• Cummins 4-cylinder water cooled diesel engine.
Designed for long life, easy maintenance and excel-
lent fuel economy.
• Engine protection system shuts the engine down for
low oil pressure, high water temperature or a broken
fan/engine alternator belt.
• Gauges for oil pressure, oil temperature, engine alter-
nator output and fuel level (on K1846-2 only codes
above 10840 have a fuel level gauge on both K1846-
1 and K1846-2).
• Indicator lights for low oil pressure, high oil tempera-
ture, engine alternator low output/broken belt and low
fuel level (on K1846-2 only for codes 10840 and
below).
• Automatic low fuel shutdown before running out of
fuel (K1846-2 only for codes 10840 and below).
• Engine hour meter standard on all models.
• Extended range 25 gallon (94.6 l) fuel tank.
• Automatic idler reduces engine speed when not weld-
ing or drawing auxiliary power. This feature reduces
fuel consumption and extends engine life.
• Compact size fits crosswise in full size pick-up truck.
• Single side engine service.
• Copper alternator windings and high temperature
insulation for dependability and long life.
• New paint system on case and base for outstanding
corrosion protection.
K1846-1 COMMANDER 500 CUMMINS Standard
Model
The K1846-1 is the standard version of the
Commander 500, and has all the features of the
K1846-2 Deluxe version except there is no oil pressure
gauge, oil temperature gauge, engine alternator
gauge, nor dual output meters (codes 10840 and
below do not have a fuel level gauge nor low fuel light).
This version does have fully functional engine protec-
tion for low oil pressure, high oil temperature, and alter-
nator output with associated lights.
• A field installed Dual Output Meter and Gauge Kit
(K1768-2) is available for the K1846-1 Commander
500. The kit includes dual output meters, oil pressure
gauge, water temperature gage, and alternator
ammeter.
WELDING CAPABILITY
The COMMANDER 500 CUMMINS is rated at 500
amps, 40 VDC at 100% duty cycle and 575 amps, 36
VDC at 50% duty cycle. The maximum open circuit
voltage at 1900 RPM is 80 volts. The weld current is
variable from 30 to 575 amps.
COMMANDER 500 CUMMINS
• Dual 3-digit output meters are provided (optional on
K1846-1) for presetting the weld amperage or voltage
and displaying the actual amperage and voltage during
welding. The meters use superbrite L.E.D.'s for
improved readability in full sunlight.
LOOK-BACK FEATURE: After welding has stopped,
both displays will remain on for 7 seconds with the last
current and voltage value displayed. During this time, the
left-most decimal point in each display will be FLASH-
ING.
• Standard remote control capability with 14 pin and 6 pin
connectors for easy connection of Lincoln remote con-
trol accessories.
• An internal "Solid State" contactor allows for the selec-
tion of "hot" or "cold" output terminals with a toggle
switch on the control panel.
• “ Arc Control ” potentiometer in Wire and Stick modes for
precise adjustment of arc characteristics.
• Advanced circuitry to prevent pop-outs in the five slope
modes.
