• CC Arc Force Control Knob with built-in “Hot Start”.
• “Idle Shut Down ode” auto atically shuts achine
off when not in use to ini ize power consu ption.
• Fan-As-Needed™ – solid state ther ally controlled
cooling fan operates only when required. Mini izes
power consu ption, 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 ost stick
and wire processes. Select low inductance for
Innershield®NR®-211-MP, NR-212, and NR-203 type
wires.
• Optional digital a eter/volt eter kit. Easy front
panel installation.
• Panel switches are behind front latched panel, for
re ote or achine panel output control, and output
“on” or re ote “on” selection, and CC, CV Subarc or
CV MIG ode selection.
• Low profile case allows stacking achines up to
three high to conserve floor space. (Stacking not
reco ended when using undercarriage).
• Electronic and ther al protection fro current
overload and excessive te peratures.
• Function lights built into the printed circuit boards
speed diagnosis.
MULTI-PROCESS WELDERS
Description
650 A p 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.
