Lincoln Electric IDEALARC CV-400-I - Manual (Page 13)

B-2 OPERATION B-2
When using a CV-400-I 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 400-I is a constant voltage DC power source
designed for the GMAW process with limited FCAW capabil-
ity as well. It features an international rating of 400 amps,
36 volts, at 60% duty cycle. It also has the capacity to run
at 300 amps, 32 volts, 100% duty cycle.
The CV 400-I is available as a European model with 42 VAC
auxiliary power only, or as an export model with both 42 VAC
and 115 VAC auxiliary power. No options are available other
than input voltage.
The European model of the CV 400-I features an all graphic
nameplate and has an IEC 974-1 S Rating for use in envi-
ronments with an increased hazard of electric shock.
RECOMMENDED PROCESSES AND
EQUIPMENT
The CV-400-I is capable of solid wire welding within
the rated output capacity of the machine. It is also
capable of welding with the following flux-cored wires:
NR-152, NR-211, NS-3M, NR-203 Ni 1%, and
Outershield® 70 and 71.
The CV-400-I (Export) is recommended for use with
the LN-7, LN-742 and LN-25 wire feeder models. The
CV-400-I (European) does not provide 115 VAC auxil-
iary power for the LN-7 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. (Except Code 10182).
• 220 VAC, 2 amp Auxiliary power available for water cool-
ers, using standard Continental European receptacle.
• 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 overloads.
• Submersion dipping of assembled transformer, choke, and
rectifier in special sealing/insulating material gives extra pro-
tection against moisture and corrosive atmospheres.
• Microprocessor based Control PC Board has built-in
diagnostic routines.
• Compact size, requires only 19" x 26" 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.
LIMITATIONS
The CV-400-I is intended only for use with the follow-
ing FCAW electrodes: NR-152, NR-211, NR-203 Ni
1%, NS-3M, Outershield 70 and 71. The machine has
been designed primarily for the GMAW process.
