FLEXTEC™ 500
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" charac-
teristics 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™ 500. Set this switch to 'Remote' 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.
