Item Symbol Description
0
Pulse break time/slope time from AMP to AMP%
• Pulse break setting range: 0.01 sec to 20.0 sec
(0.01 sec increments < 0.5 sec; 0.1 sec increments > 0.5 sec)
• Slope time (tS1) setting range: 0.0 sec to 20.0 sec
(see chapter "Advanced settings").
7
sec
TIG pulses
The pulse break time applies to the
secondary current phase (AMP%)
TIG AC Special
The pulse break time applies to the DC
phase with AC special.
8
AMP%
Secondary current (TIG) / pulse pause current
Setting range 1% to 100% (1% increments). Percentage of the main current.
9
sec
Down-slope time (TIG)
0.00 sec to 20.0 sec (0.1 sec increments).
The down-slope time can be set separately for non-latched and latched.
10
AMP%
End-crater current (TIG)
Setting range 1 % to 200 % (1 % increments). Percentage of the main current.
11
sec
Gas post-flow time (TIG)
Setting ranges: 0.00 sec to 40.0 sec (0.1 sec increments).
12
“Tungsten electrode diameter”/“Ignition optimisation” LED
Infinitely adjustable from 1 mm to 4 mm or greater
Alternating current balance (TIG AC)
Max. setting range: -30% to +30% (1% increments). The setting range may also be
lower depending on the factory setting.
Optimisation of cleaning effect and fusion penetration characteristics.
13
Balance fast TIG DC pulses
Setting range: 1% to +99% (1% increments)
Alternating current frequency (TIG AC)
50 Hz to 200 Hz (1 Hz increments)
Constriction and stabilisation of the arc:
At a higher frequency, the cleaning effect is increased. Particularly thin panels (welding
with a low current), anodised sheet aluminium or highly contaminated articles for
welding can be welded and cleaned perfectly at a higher frequency.
14
Frequency fast TIG DC pulses
Setting range: 50 Hz to 2.5 kHz (0.01 kHz increments)
15
"activArc" LED
Display activArc activated (on/off) function and correction of the activArc characteristic.
Setting range: 0..100

Operating concepts
The welding task (JOB) can be selected in two ways:
• Manual, standard operation (JOB "0")
• JOB operation, saved welding tasks (JOB 1 to 7)
