Lincoln Electric IDEALARC CV-305 - Manual (Page 16)

OPERATION B-4 B-4
IDEALARC® CV-305
When using a CV-305 power source with wire feeders,
there will be a small spark if the electrode contacts the
work or ground within several seconds after releasing
the trigger.
When used with some wire feeders with the electrical
trigger interlock in the ON position, the arc might restart
if the electrode touches the work or ground during
these several seconds.

GENERAL DESCRIPTION
The CV-305 is a constant voltage DC power source
designed for the GMAW process with limited FCAW
capability as well. It features an industrial rating of 315
amps, 32.6 volts, at 100% duty cycle. It complies with
the requirements for a NEMA Class I (100) power
source.
It is available from the factory in one model only, with
no options other than input voltage or frequency.
RECOMMENDED PROCESSES AND
EQUIPMENT
The CV-305 is capable of solid wire welding within the
rated output capacity of the machine. It is also capa-
ble of welding with flux-cored wires.
The CV-305 is recommended for use with the LF-72,
LN-7, LN-742 and LN-25 wire feeder models.
OPERATIONAL FEATURES AND
CONTROLS
• Two inductance positions: operator can choose the
optimum output characteristics.
• Solid State Output Contactor: no noise, no moving
parts to wear.
• Digital Voltmeter/Ammeter is standard.
• Power on/off switch.
• 42 VAC, 10 amp auxiliary power available for the
wire feeder.
• Circuit breaker protected.
• 115 VAC, 5 amp auxiliary power available for the wire
feeder; circuit breaker protected.
• Magnum Twist-Mate™ output receptacles.
• Single MS-type (14-pin) connection for wire feeder.
• Solid state controls, with line voltage compensation.
• Optional remote control capability.
DESIGN FEATURES
• "Clean" appearance and simple controls -- easy to
operate.
• Electronic and thermostatic protection from over-
loads.
• Submersion dipping of assembled transformer,
choke, and rectifier in special sealing/insulating
material gives extra protection against moisture and
corrosive atmospheres.
• Microprocessor based Control PC Board has built-in
diagnostic routines.
• Compact size, requires only 19" x 26"(482mm x
660mm) footprint.
• Modular construction for easy servicing.
• Recessed panels protect output studs and controls.
Large safety margins and protective circuits protect
rectifiers from transient voltages and high currents.
POWER SOURCE OPERATION
Be sure the CV-305 is properly installed, and that all
accessories are properly hooked up before attempting
operation.
