MULTI-PROCESS WELDERS

DC-655

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.

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.
