SAFETY PRECAUTIONS

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 danger-

ous.

• 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 closed containers.

------------------------------------------------------------------------

ARC RAYS can burn eyes and skin.

• Wear eye, ear and body

protection.

WARNING

GENERAL DESCRIPTION

The Invertec V350-Pro offers multi-process CV, CC,

and DC welding and is rated 350 amps, 34 volts at a

60% duty cycle. The V350-Pro is available in several

versions of wire feeder connections. In the different

configurations, the V350-Pro is available in either a

Construction version (no wire feeder connection and

auxiliary power) and a Factory & Advance Process

versions (includes wire feeder connection and related

power).

DUTY CYCLE

The V350-Pro is rated at 350 amps, 60% duty cycle

(based on a 10 minute cycle). It is also rated at 275

amps, 100% duty cycle.

OPERATIONAL FEATURES and CONTROLS:

UPPER CONTROL PANEL

1. AMPS Meter

• Prior to STICK or TIG operation (current flow), the

meter displays preset current value (either 2 amps

or +/- 3% (e.g. 3 amps on 100), whichever is

greater).

• Prior to CV operation, the meter displays four dash-

es indicating non-presettable AMPS.

• During welding, this meter displays actual average

amps.

• After welding, the meter holds the actual current

value for 5 seconds. Output adjustment while in the

"hold" period results in the "prior to operation" char-

acteristics stated above. The displays blink indicat-

ing that the machine is in the "Hold" period.

2. VOLT METER

• Prior to CV operation (current flow), the meter dis-

plays desired preset voltage value (+/- .5V).

• Prior to STICK or TIG operation, the meter displays

the Open Circuit Voltage of the Power Source or

four dashes if the output has not been turned on.

• During welding, this meter displays actual average

volts.

• After welding, the meter holds the actual voltage

value for 5 seconds. The displays blink indicating

that the machine is in the "Hold" period.

• Output adjustment while in the "hold" period results

in the "prior to operation" characteristics stated

above.

3. OUTPUT CONTROL

• Output control is conducted via a single turn poten-

tiometer.

• Adjustment is indicated by the meters as stated

above.

• When in TIG modes, this control sets the maximum

welding current. Full depression of a foot or hand

Amptrol results in the preset level of current.

4. WELD TERMINALS-REMOTE / ON

• Two status lights indicate the location of trigger con-

trol as determined by the "WELD TERMINALS"

push button.

• If trigger control is local "weld terminals on", the ON

display will be lit.

• If trigger control is remote "weld terminals remotely

controlled", the REMOTE display will be lit.

• The unit will power up in "pre-determined preferred"

trigger modes.

For the Construction version all modes ON.

For the Factory and Advanced Process version

STICK = ON

TIG and CV = ON or REMOTE depending if remote

output controls are connected to the machine.
