CV-655
Energy efficiency, reliability and exceptional performance are what set the CV-655 apart from
the rest. Designed primarily for heavy-duty applications, the CV-655 is an outstanding choice
for MIG and flux-cored welding on mild steel, stainless steel, aluminum and alloys.
• Calibrated output control lets operator accurately
regulate power levels.
• Line voltage compensation maintains weld consistency,
even with line voltage changes of ±10%.
• 115-volt duplex receptacle provides 20 amps of auxiliary
power.
• Separate output studs allow the operator to select high
or low inductance.
• Panel switches allow operator to change settings at
the power source or wire feeder.
• Solid state circuitry provides extra long life during
repetitive applications.
• Three-year warranty on parts and labor.
• Seven-year warranty on power rectifier.

Invertec
®
STT ® II
The revolutionary STT ® II power source combines high frequency inverter
technology with advanced Waveform Control Technology ® to provide a
better welding solution than traditional short arc MIG.
Featuring Surface Tension Transfer ® Process
• Controlled penetration and outstanding heat input control—Ideal
for welding joints with open root, gaps, or on thin material with
no burnthrough.
• Reduced spatter and fumes—Current is controlled to achieve
optimal metal transfer.
• Various shielding gases—STT ® may be used with various gas
blends of Argon including Helium or 100% CO
2
with larger
diameter wires.
• Good bead control and faster travel speeds—Can replace TIG
(GTAW) in many applications without sacrificing appearance.
• Background and Tailout Current—accurately control fine and
coarse heat input for reduced distortion and burnthrough as
well as proper penetration.
• Adjustable Hot Start controls the heat at the start of the weld.
• Three-year warranty on parts and labor.
