Features

• Large, conveniently located switch makes it easy to change between CC (Stick/TIG/arc gouging), CV (MIG/flux-cored) and CV Submerged Arc modes.
• Arc force control adjusts short circuit current for a soft arc or a forceful driving arc in the CC (Stick/TIG) mode.
• Arc control adjustment changes pinch effect of the arc to control spatter, fluidity, and bead shape in the MIG/Flux-Cored mode.
• Capable of stick and DC TIG welding, and air carbon arc gouging with up to 5/16" diameter carbon rods.
• Solid state circuitry provides extra long life for repetitive welding applications.
• Outstanding welding performance with a single range full output control potentiometer.
• Analog ammeter/voltmeter are standard.
• +/-10% input line voltage compensation for maintaining weld consistency.
• Low profile case allows stacking machines up to three high to conserve floor space. (Stacking not recommended when using undercarriage.)
• Fan cooled for long life expectancy. Electronic and thermostatic protection safeguard DC-4000 from current overload and excessive temperatures.
• Windings and rectifiers protected against moisture and corrosive environments.
• Both 14 pin MS-style cable connection and terminal strip access for remote control and wire feeder connections and output studs for weld cables.
• Circuit breaker protected on-board power for a wire feeder: 115V available from the terminal strip, 42V and 115V available from the 14-pin connector receptacle.
• 115V AC power on/off switch with pilot light provides added user safety.
• Durable powder paint system protects both sides of all painted surfaces to prolong machine's life.
