RECOMMENDED APPLICATIONS
WELDER
The Commander 500 provides excellent constant cur-
rent DC welding output for stick (SMAW) and TIG weld-
ing. The Commander 500 also provides excellent con-
stant voltage DC welding output for MIG (GMAW) and
Innershield (FCAW) welding.
GENERATOR
The Commander 500 provides smooth 120/240 VAC
output for auxiliary power and emergency standby
power.
DESIGN FEATURES AND ADVANTAGES
K1639-2 COMMANDER 500 DELUXE MODEL
FEATURES
FOR WELDING
• Excellent DC multi-purpose welding for stick, MIG,
TIG, cored wire and arc gouging applications.
• 30 to 500 amps output in five slope-controlled ranges
for out-of position and pipe electrodes, one constant
current output range for general purpose welding,
one constant voltage range for MIG wire and cored
wire welding and one 20-250 amp range for “Touch
Start” TIG welding.
• 100% duty cycle at 500 amps output and 50% duty
cycle at 575 amps output.
• Dual 3-digit output meters are provided (optional on
K1639-1) for presetting the weld amperage or volt-
age 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 FLASHING.
• Standard remote control capability with 14-pin and
6-pin connectors for easy connection of Lincoln
remote control accessories.
• An internal "Solid State" contactor allows for the
selection 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.
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
connection to premises wiring.
• Weld and AC auxiliary power at the same time (with-
in machine total capacity).
OTHER FEATURES
• Deutz 3-cylinder, air/oil 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 oil temperature, or a broken
fan/engine alternator belt.
• Gauges for oil pressure, oil temperature, engine
alternator output, and fuel level.
• Indicator lights for low oil pressure, high oil tempera-
ture, engine alternator low output/broken belt, and
low fuel level (on K1639-2 only).
• Automatic low fuel shutdown before running out of
fuel (K1639-2 only).
• Engine hour meter standard on all models.
• Extended range 25 gallon (94.6 l) fuel tank.
• Automatic idler reduces engine speed when not
welding or drawing auxiliary power. This feature
reduces fuel consumption and extends engine life.
• Compact size fits crosswise in full size pickup 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.
