FLEXTEC
®
500X
DUTY CYCLE
The Flextec
®
500X is capable of welding at a 100% duty cycle
(continuous welding) at 450 Amps rated output.
The 60% duty cycle rating is 500 amps (based off of a ten minute
cycle – 6 minutes on time and 4 minutes off time). The maximum
output of the machine is 500 amps.
The Flextec
®
500X is also rated for Desert Duty, elevated
temperature operation, in a 55°C ambient. The machine is de-
rated for this application.
COmmON wELDING PROCEDURES
MAKING A WELD
®
The Flextec
500X is a multi-process inverter welder. The Weld
Process Selector Switch is used to set the desired weld mode.
The Flextec
®
500X has 5 selectable welding modes:
1. SMAW – This is a CC (constant current) weld mode used for
the SMAW stick welding process.
2. GTAW – This is a CC (constant current) weld mode used for
the GTAW tig welding process.
3. CV – This is CV (constant voltage) weld mode used for
welding the GMAW mig welding process and the FCAW-GS,
flux cored gas shielded welding process.
4. CV-Innershield – This is a CV (constant voltage) weld mode
used for welding the FCAW-SS, flux cored self shielded
welding process
5. ArcLink – This weld mode position is used to unlock synergic
modes when combined with an ArcLink wire feeder.
6. Constant Current Test Mode – When the switch is in the
ArcLink position with no ArcLink feeder present, the Flextec
will go into constant current test mode. This can be used to
verify the calibration of the Flextec
The machine is also capable of gouging. Gouging can be done in
either the SMAW mode or the CV and CV-Innershield modes.
In addition to the Weld Mode Selector switch, a hot start dial,
output control dial and arc control dial are provided to setup and
fine tune the welding procedure.

DEFINITION OF wELDING mODES
NON-SYNERGIC WELDING MODES
• A Non-synergic welding mode requires all welding process
variables to be set by the operator.
SYNERGIC WELDING MODES
• A Synergic welding mode offers the simplicity of single knob
control. The machine will select the correct voltage and amperage
based on the wire feed speed (WFS) set by the operator.
wELD CONTROLS AND DISPLAYS
Weld Process Selector Switch
5 Position switch used to select the welding process
Hot Start Dial
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 Dial
Full range selection of arc control from -10 to +10. In CV mode,
this control is an inductance control. In stick mode, the control
adjusts the arc force.
Output Control Dial
Output control is conducted via a single turn potentiometer.
Adjustment is indicated by the meters.
When in remote modes, this control sets the maximum welding
current or voltage output. Full depression of a foot or hand amptrol
results in the preset level of current or voltage.
Volt Display Meter
• Prior to CV operation (current flow), the meter displays desired
preset voltage value (+/- .1V).
• Prior to STICK or TIG operation, the meter displays four dashes if
the output has not been turned on.
• During welding, this meter displays actual average volts.
• After welding, the meter holds the actual voltage value for 5 seconds.
The displays blink indicating that the machine is in the "Hold" period.
• Output adjustment while in the "hold" period results in the "prior
to operation" characteristics.
