Voltage Display
– This display will display the pre-set
welding voltage when the machine is in the idle state.
After welding, the meter holds the actual voltage value
for 5 seconds. Output adjustment while in the "hold"
period results in the "prior to operation" characteristics
stated above. The displays blink indicating that the
machine is in the "Hold" period.
Output Control Local/Remote
– When the control is
set to local (no remote potentiometer/control plugged
into the 12-pin or 14-pin connectors), the output is
controlled through the Output Control dial on the front of
the FLEXTEC 350x CE. Set this switch to ‘Remote’
when an external potentiometer/control is connected or
using a CrossLinc™ feeder.
Output Control Dial
When the Local/Remote is set to Local, this dial
sets the welding voltage.
When the Local/Remote is set to Remote, and the
weld terminal switch is in the ‘ON’ position, this dial
sets the maximum welding voltage. The remote
potentiometer controls the voltage from minimum
to this pre-set maximum. If the weld terminal switch
is in the ‘REMOTE’ position, the output is
controlled via the 14-pin input.
ArcLink
This weld mode is intended to unlock basic non-
synergic and synergic modes intended for use with a
compatible ArcLink wire feeders. All of the Flextec350x
CE user interface controls are disable in this mode and
controlling the power source is accom- plished from the
wire feeder user interface.

Amperage Display
– This display will display three
dashed lines when the machine is in the idle state. This
indicates that amperage is not settable in this weld
mode. While output is enabled, the actual welding
amperage will be displayed. After welding, the meter
holds the actual amperage value for 5 seconds. Output
adjustment while in the "hold" period results in the "prior
to operation" characteristics stated above. The displays
blink indicating that the machine is in the "Hold" period.

Maintenance
WARNING
Before carrying out service, maintenance
and/or repair jobs, fully disconnect power to
the machine.
WARNING
Use Personal Protective Equipment (PPE),
including safety glasses, dust mask and
gloves to avoid injury. This also applies to
persons who enter the work area.
WARNING
MOVING PARTS can injure.
Do not operate with doors open or
guards off.
Stop engine before servicing.
Keep away from moving parts
WARNING
Have qualified personnel do all
maintenance and troubleshooting work.
Visual Inspection
Clean interior of machine with a low pressure air
stream. Make a thorough inspection of all components.
Look for signs of overheating, broken leads or other
obvious problems. Many problems can be uncovered
with a good visual inspection.
Routine Maintenance
Every six months the machine should be cleaned with a
low pressure air stream. Keeping the machine clean will
result in cooler operation and higher reliability. Be sure
to clean the following areas:
All
printed
circuit
boards
Power
switch
Main
transformer
Input
rectifier
Heatsink
fins
Auxiliary
Transformer
Fans (Blow air through the rear louvers)
Examine the sheet metal case for dents or breakage.
Repair the case as required. Keep the case in good
condition to ensure that high voltage parts are protected
and correct spacing is maintained throughout. All
external sheet metal screws must be in place to ensure
case strength and electrical ground continuity.
Current Calibration
1. Connect the resistive load band and test voltmeter
to the welding output terminals.
2. Put dipswitch 1 in the on position.
3. Rotate the Hot Start knob and Arc Control knob to
the minimum.
4. Turn on the FLEXTEC 350x CE.
5. The display should read “Cur CAL”.
6. Rotate the Hot Start knob until a message scrolls
across the screen.
7. Adjust the output control knob until the actual
output amperage reading on the test ammeter is
300 amps +/- 2 amps.
8. Toggle the Local/Remote switch to save the
calibration.
9. The display should flash “CAL SEt”.
