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
PRODUCT DESCRIPTION & DUTY CYCLE
The Invertec V350-PRO (CE) offers multi mode CV
and CC DC welding and is rated at 350 amps, 34 volts
at a 60% duty cycle with 3 phase input. It is also rated
at 320 amps with single phase input. It is 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.
STICK = ON
TIG and CV = ON or REMOTE depending if remote
output controls are connected to the machine.
