No remote control or trigger required. Amperage can be controlled at the control
panel or with a remote potentiometer. Blue output on LED illuminates to indicate out-
put is on.
Pulsing is available in the TIG process. Controls can be adjusted while welding.
Reduces heat input to minimize distortion and increase travel speed. Range is 0.1 to 500 pulses per second.
Press button to enable pulser.

See Section 15 for additional Pulser information, or visit
guides.
Parameter/Setting Description
Display
[PPS] [100] *Pulses Per Second: range is 0.1- 500.
[PK T] [40%] *Peak Amperage Time: range is 5–95%.
[BK A] [25%] *Background Amperage Time: range is 5- 95% of peak amperage value.
The welding output can be programmed to specific amperages and durations for repetitive applications. Se-
quencer is only available in the TIG process. Sequencer is disabled if a remote control with variable amperage is
connected to the machine.

See Section 10 for setting weld time.
Parameter/Setting Description
Display
[INTL] [20A] Initial Amperage: Range is min - 280 amps.
[ISLP] [OFF] Initial Slope Time: Range is OFF - 50.0T (seconds).
[FSLP] [OFF] Final Slope Time: Range is OFF - 50.0T (seconds).
[FNL] [10A] Final Amperage: Range is min - 280 amps.
Parameter/Setting Description
Display
[PRE] [0.2T] Preflow Time: Controls length of time gas flows prior to arc start. Range is OFF-25T
(seconds).
[POST] [AUTO] Post Flow Time:
Increasing setting increases length of time gas flows after welding stops. Range is
OFF - 50T (seconds). AUTO calculates the time based on the maximum amperage
of each welding cycle. The minimum time is 8 seconds. Auto = maximum amperage/
10.
[DIG] [30%] *Arc Force Control:
Controls the amount of additional amperage at low voltage (short arc length) condi-
tions. Adjust the force of the arc for different joint configurations and electrodes.
Range is OFF - 100%. PRO-Set values available for both 6010 and 7018 electrodes
Carbon ARC Gouging can be selected at one step above DIG's 100%.
Weld output terminals are energized at all times when displays read
[OUT] [ON].
