FLEXTEC ® 500X
bASIC mODES OF OPERATION
SMAW
This weld mode is a constant current (CC) mode featuring
continuous control from 15 – 500 Amps.
It is intended for the SMAW stick welding processes and arc
gouging. The mode can also be used for TIG operation without
changing modes.
Hot Start - The Hot Start control regulates the starting current at
arc initiation. Hot Start can be set to '0" and no additional current
is added at arc start. Increasing from 0 to 10 will increase the
additional current (relative to the preset current) that is added at
arc initiation.
Arc Control - The Arc Control regulates the Arc Force to adjust the
short circuit current. The minimum setting (-10) will produce a
"soft" arc and will produce minimal spatter and shallow
penetration. The maximum setting (+10) will produce a "crisp"
arc and will minimize electrode sticking with deeper penetration.
Weld Terminals On/Remote – Set to "On" so the machine is in the
ready to weld state. Setting the machine to "On" enables the
machine OCV.
Voltage LCD Display – This display will display three dashed lines
when the machine is in the idle state. This indicates that voltage
is not settable in this weld mode. While output is enabled, the
actual welding voltage will be displayed. 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.
Amperage LCD Display – This display will display the pre-set
welding current when the machine is in the idle state. 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.
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.
• When a remote potentiometer is connected, the output control
®
on the Flextec and the remote act as a master/slave config-
uration. Use the output control dial on the Flextec
maximum welding current. The remote will control output from
minimum to the pre-set maximum.
Output Control Dial
• When the Local/Remote is set to Local, this dial sets the welding
amperage.
• When the Local/Remote is set to Remote, this dial sets the
maximum welding amperage. The remote potentiometer than
controls the amperage from minimum to this pre-set maximum.

GTAW
This weld mode is a constant current (CC) mode featuring
continuous control from 10 –500 amps.
It is intended for the GTAW TIG welding processes.
Hot Start - Hot start regulates the arc initiation current. A setting
of +10 results in the most positive arc initiation.
Arc Control – This control is not used in the GTAW mode.
Weld Terminals On/Remote
• When set to the 'ON' position, the weld terminals are at OCV
(open circuit voltage) and ready to weld.
• When set to the 'remote' position, output is enabled through a
remote trigger.
Voltage LCD Display – This display will display three dashed lines
when the machine is in the idle state. This indicates that voltage is
not settable in this weld mode. While output is enabled, the actual
welding voltage will be displayed. 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.
• When a remote potentiometer is connected, the output control
on the Flextec ® and the remote act as a master/slave config-
uration. Use the output control dial on the Flextec
maximum welding current. The remote will control output from
minimum to the pre-set maximum.
Output Control Dial
• When the Local/Remote is set to Local, this dial sets the welding
amperage.
• When the Local/Remote is set to Remote, this dial sets the
maximum welding amperage. The remote potentiometer than
controls the amperage from minimum to this pre-set maximum.
