Pulse Control
Pulsing is available in the TIG process. Controls can
be adjusted while welding.
Reduces heat input to minimize distortion and in-
crease travel speed. Range is 01. to 500 (pulses per
second).
Press switch pad to enable pulser.
[PPS]* Pulses Per Second: Range is 0.1
− 500.
[PK T]* Peak Amperage Time: Range is 5 − 95%
[BK A]* Background Amperage Time: Range is 5 −
95% of peak amperage value.
Sequencer Control
The welding output can be programmed to spe-
cific amperages and durations for repetitive ap-
plications. 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
− 210
amps.
[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
− 210
amps.
(See Sections 11-2 and 11-3 for setting weld
time.)

Gas/DIG Control
[PRE] Preflow Time:
Controls length of time gas flows prior to arc start.
Range is OFF
− 25T (seconds).
[POST] 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]* 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 configura-
tions 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%.
AC Waveshape Control
[BAL] Balance Control (%EN) TIG Only:
Controls oxide cleaning. Increasing the setting
reduces cleaning. 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. (See tips in Section 6-2).
[FREQ] AC Frequency (Hz):
Controls arc width. Increasing the setting nar-
rows the arc width. Range is 20 to 400 Hz. (See
tips in Section 6-2).
