Pulse Control
100
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 01. to 500 pulses per second AC (Dynasty
40%
only) or 01. to 5000 pulses per second DC.
Press switch pad to enable pulser.
[PPS]* Pulses Per Second: Range is 0.1− 500.
25%
[BK A]* Background Amperage Time: Range is 5− 95% of peak
amperage value.

Sequencer Control
20A
The welding output can be programmed to specific amperages
and durations for repetitive applications. Sequencer is only
available in the TIG process. Sequencer is disabled if a remote
control with variable amperage is connected to the machine.
[INTL] Initial Amperage: Range is min − 400/800 amps.
OFF
[ISLP] Initial Slope Time: Range is OFF − 50.0T (seconds).
[FSLP] Final Slope Time: Range is OFF − 50.0T (seconds).
[FNL] Final Amperage: Range is min − 400/800 amps.
(See Sections 9-1 and 9-2 for setting weld time.)
OFF
10A
Gas/DIG Control
[PRE] Preflow Time:
0.2T
Controls length of time gas flows prior to arc start.
Range is OFF−25T (seconds).
[POST] Post Flow Time:
AUTO
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.
30%
[DIG]* Arc Force Control:
Controls the amount of additional amperage at low voltage
(short arc length) conditions. 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 elec-
trodes
CARBon ARC Gouging can be selected at one step above
DIG's 100%.
AC Waveshape Control (Dynasty Only)
150A
[ENEP] EN Amperage and EP Amperage TIG only:
Controls both electrode negative and positive amperage value.
.
Both EN Amperage and EP Amperage LEDs will be lit.
75% .
See Section 6-3 to select Independent EN and EP Amper-
age control.
[BAL] Balance Control (%EN) TIG Only:
Controls oxide cleaning. Increasing the setting reduces clean-
120H
ing. Range is BALL, 50 − 99%. Stick is fixed at 50%. "BALL"
sets the Balance to 30%. This is to allow the operator to form
a ball on the tip of the tungsten. It is not for normal welding
operation.
[FREQ] AC Frequency (Hz): Controls arc width. Increasing the
setting narrows the arc width. Range is 20 to 400 Hz.
