Machine description – quick overview
Description 0
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.
End-crater current (TIG)
Setting range 1 % to 200 % (1 % increments). Percentage of the main current.
Gas post-flow time (TIG)
Setting ranges: 0.00 sec to 40.0 sec (0.1 sec increments).
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.
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:
The cleaning effect increases with a greater frequency. 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.
Frequency fast TIG DC pulses
Setting range: 50 Hz to 15 kHz
Welding current polarity, MMA
(see chap. "Switching the welding current polarity")
activArc TIG welding process
•
Switch activArc on or off
•
Correct the activArc characteristic (setting range: 0 to 100)
