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.
