Recommended TIG Options
• 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" (8mm) 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 maintain-
ing weld consistency.
• Low profile case allows stacking machines up to
three high to conserve floor space. (Stacking not
recommended when using undercarriage.)

Description
This heavy-duty, industrial, three-phase multi-process power source from
Lincoln Electric scores big in MIG, flux-cored, submerged arc, stick and DC
TIG welding. It's a great choice for arc gouging too. And flexibility doesn’t
mean complicated – the DC-400 is easy to set-up and use. Changeover
between processes is as simple as turning a switch with the factory or field
installed multi-process switch. On-board ammeter and voltmeter make
monitoring of key welding parameters a snap. Inductance and arc force
controls allow the operator to efficiently refine the arc for the job at hand.
