Recommended TIG Options
• CC Arc Force Control Knob with built-in “Hot Start”.
• “Idle Shut Down mode” automatically shuts machine
off when not in use to minimize power consumption.
• Fan-As-Needed™ – solid state thermally controlled
cooling fan operates only when required. Minimizes
power consumption, operating noise and dust intake.
• Full range calibrated output voltage and current
control for easy operation.
• Separate output studs let you choose low or high
inductance. Select high inductance for most stick
and wire processes. Select low inductance for
Innershield
®NR®
-211-MP, NR-212, and NR-203 type
wires.
• Optional digital ammeter/voltmeter kit. Easy front
panel installation.
• Panel switches are behind front latched panel, for
remote or machine panel output control, and output
“on” or remote “on” selection, and CC, CV Subarc or
CV MIG mode selection.
• Low profile case allows stacking machines up to
three high to conserve floor space. (Stacking not
recommended when using undercarriage).
• Electronic and thermal protection from current
overload and excessive temperatures.
• Function lights built into the printed circuit boards
speed diagnosis.
MULTI-PROCESS WELDERS
Description
650 Amp DC Multi-Process Welding Power Source
This 650-amp, 100% duty cycle CV/CC power source is ideal for construction
and shop fabrication because of its excellent arc performance and many energy
saving features.This machine also has a high overall efficiency of 84% for even
more energy and cost savings.Save money with the idle shut down timer that
powers down the DC-655 when not in use for extra energy conservation. Keep
internal components cool without wasting energy with Lincoln’s Fan-As-Needed
(F.A.N.) that shuts off automatically when the system is cooled. Don’t think you’re
sacrificing arc performance for efficiency; the DC-655 features a calibrated output
knob for precise procedure setting and adjustable arc force for a tailored arc and
ultimate low end performance – down to 50 amps – for excellent stick, MIG
and TIG performance.
