Tungsten Balling Function - EWM T4.02 Operating Instructions Manual

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, conse-
quently, 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. Tungs-
ten balling should be performed on a test component as surplus tungsten may be melted and this may
lead to impurities on the weld seam.
