FLEXTEC™ 500
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™ 500. Set this switch to 'Remote' 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 configuration.
Use the output control dial on the Flextec™ to set the 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.
