Alternating current balance (TIG AC)
Max. setting range: -15% to +15% (1% increments). The setting range may also be
lower depending on the factory setting.
Optimisation of cleaning effect and fusion penetration characteristics.
An increase in the positive half-wave means:
• greater cleaning effect
• higher temperature of the tungsten electrode
• greater ball formation on the tungsten electrode
• broader weld seam, little fusion penetration
An increase in the negative half-wave means:
• narrower weld seam, deeper fusion penetration
• reduced cleaning effect
• lower temperature of the tungsten electrode
• less ball formation on the tungsten electrode
2
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.
3
Welding current rotary dial
Infinitely adjustable welding current, 0% to 100% of the main current preset on the
power source.
4
19-pole connection socket (analogue)
For connecting the control lead.
5
Remote control connector cable
Use a 5, 10, or 20 m connector cable, depending on the design, for connecting the
remote control to the power source.
