FLEXTEC ® 500X
CV-Gas
This weld mode is a constant voltage (CV) mode featuring
continuous control from 10 to 45 volts.
It is intended for the GMAW, FCAW-GS, MCAW welding processes
and arc gouging.
Hot Start – Rotate from the '0' position to the '10' position to
provide more energy during the start of a weld.
Arc Control – The Arc Control regulates pinch effect. At the
minimum setting (-10), minimizes pinch and results in a soft arc.
Low pinch settings are preferable for welding with gas mixes
containing mostly inert gases as well as aluminum alloys. At the
maximum setting (+10), maximizes pinch effect and results in a
crisp arc. High pinch settings are preferable for welding FCAW and
GMAW with CO2.
Weld Terminals On/Remote
• When set to the 'ON' position, the weld terminals are at OCV
(open circuit voltage) and ready to weld. This selection is used
for across the arc wire feeders. The 12-pin connector remote
input is used to adjust the voltage with a master/slave
relationship with the output control dial.
• When set to the 'remote' position, output is enabled through a
remote trigger. The 14-pin connector remote input is used to
adjust the voltage with a master/slave relationship with the
output control dial.
Amperage LCD 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.
Voltage LCD 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
when an external potentiometer/control is connected.
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.

CV-Innershield
This weld mode is a constant voltage (CV) mode featuring
continuous control from 10 to 45 volts.
It is intended for the FCAW-SS welding process and arc gouging.
Hot Start – Toggle from the '0' position to the '10' position to
provide more energy during the start of a weld.
Arc Control – The Arc Control regulates pinch effect. At the
minimum setting (-10), minimizes pinch and results in a soft arc. At
the maximum setting (+10), maximizes pinch effect and results in a
crisp arc.
