CV-525
GENERAL DESCRIPTION
The CV-525 is an SCR controlled DC power source with
a single range potentiometer control of the voltage out-
put. The primary voltage is 380-415VAC 50/60Hz for sin-
gle input voltage machine and 220/380-415/440V
50/60Hz for triple input voltage machine. The power
source complies with IEC 60974-1 requirements.
The CV-525 base model is shipped with a standard con-
trol panel and an advanced control panel is available as
field-installed option. The main new feature of this prod-
uct is it works with Arcweld AWF wire feeders, Panasonic
and OTC style cable-driven wire feeders as well as
Lincoln
’ s standard wire feeders. Control functions like
Gas Purge, 2T/4T trigger, and Crater Fill Settings are
part of the front Panel for Arcweld AWF wire feeders.
The control functions on the optional panel include Spot
Weld ON/OFF and Timer, Run-in Speed Setting, and
Burn-back Timer.
CV-525 interface with Panasonic style or OTC style wire
feeder through two different 6-pin connectors labeled as
WF-AWF/P and WF-O. Cold inch, wire feed speed and
arc voltage can be set on their feeder control panel. Cold
inch, wire feed speed, arc voltage and gas purge can all
be set remotely on the feeder control panel of the
Arcweld AWF wire feeder. The plug-in of a Panasonic
style or OTC style wire feeder will be auto-sensed and
indicated with the feeder ready light on the front panel.
A receptacle of 36VAC auxiliary power and a circuit
breaker are located at the back of the machine for gas
heaters.
RECOMMENDED PROCESSES
& EQUIPMENT
The CV-525 is recommended for use with all the pro-
cedures of solid wire Gas Metal-Arc, cored wire outer-
shield GMA as well as Innershield process within its
capacity of 60 to 525 amps.
This power source is designed to work with Lincoln ’ s
Automatic wire feeders and semiautomatic wire feed-
ers with the control cable having a 14 pin Amphenol
connector. It is also designed to work with the cable-
driven Panasonic style, OTC style wire feeders and the
Arcweld AWF wire feeder AWF-2 and AWF-4.
ARC CHARACTERISTICS
Through the unique combination of the transformer,
three phase semiconverter rectifier, capacitor bank,
and output choke design, in conjunction with the solid
state control system, an outstanding constant voltage
welding performance is achieved with a fixed pinch
setting optimized for the most popular arc characteris-
tics.
ELECTRIC SHOCK
can kill.
• Do not touch electrically live parts
or electrode with skin or wet
clothing.
• Insulate yourself from work and
ground.
• Always wear dry insulating
gloves.
FUMES AND GASES
can be dangerous.
• Keep your head out of fumes.
• Use ventilation or exhaust to
remove fumes from breathing
zone.
WELDING SPARKS
can cause fire or
explosion
• Keep flammable material away.
• Do not weld on containers that
have held combustibles.
ARC RAYS
can burn.
• Wear eye, ear and body
protection.
