Tungsten balling function
The tungsten balling function provides optimum tungsten balling, ensuring that the best ignition and
welding results are achieved during AC welding.
Optimum tungsten balling requires a sharpened electrode (about 15–25°) and the set electrode diameter
on the machine control. The set electrode diameter affects the current for tungsten balling and,
consequently, also the ball size.
Press the tungsten balling push-button to activate the function. If required, this current can be adjusted on
an individual basis using the
is started by non-contact ignition (HF start). The balled end is formed and the function then ends.

may lead to impurities on the weld seam.
