Polarity changeover (TIG manual) button
Select material type (TIG
Synergic) key button
DC welding with positive polarity on the
electrode holder in relation to the
workpiece (pole reversing switch, MMA
only).
Chrome/nickel alloys / iron /
steel alloys
DC welding with negative polarity at the
torch (or electrode holder) with respect
to the workpiece.
Copper / copper alloys
(bronzes) / copper/zinc alloys
(brass)
AC welding with rectangular current
output wave form. Maximum power
loading and safe welding.
Aluminium/magnesium alloys
AC welding with trapezoidal current
output wave form. An all-rounder,
suitable for most applications.
Aluminium/silicon alloys
AC welding with sinusoidal current
output wave form. Low noise level.
99% aluminium

1.0mm,
1.6mm,
2.0mm,
2.4mm,
3.2mm,
4.0mm or greater
Best ignition and stabilisation of the arc (DC, AC) and optimum spherical cup formation
in the tungsten electrode according to the electrode diameter being used. The
adjustable welding current is limited to the maximum permissible welding current of the
tungsten electrode.
