AMP%
Secondary current (TIG) / pulse pause current
Setting range 1 % to 100 % (1 % increments). Percentage of the main current.
8
sec
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 5.13.12 Pulse variants chapter"
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.
9
sec
Down-slope time (TIG)
0.00 s to 20.0 s (0.1 s 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
Balance
TIG AC
Optimising cleaning effect and penetration characteristics. Max. setting range: -30% to
+30% (increments of 1%). Depending on the factory settings, the setting range can be
smaller as well.
TIG DC kHz-pulsing (metallurgical pulsing)
Setting range: 1% to +99% (increments of 1%)
MMA pulse welding
Setting range: 1% to +99% (increments of 1%)
13
Frequency
TIG AC
Constriction and stabilisation of the arc:
The cleaning effect increases with a higher frequency. Especially thin metal sheets
(welding with low current), anodised aluminium sheets or very impure weld metals can
be welded and cleaned immaculately with higher frequency.
50 Hz to 200 Hz (increments of 1 Hz).
TIG DC kHz-pulsing (metallurgical pulsing)
Setting range: 0.05 kHz to 15 kHz
MMA pulse welding
Setting range: 0.2 Hz to 500 Hz
14
AC/DC Welding current polarity, MMA
- See 5.14.3 Welding current polarity reversal (polarity reversal) chapter
15
activArc TIG welding process
• Switch activArc on or off
• Correct the activArc characteristic (setting range: 0 to 100)
