The electrodes used are a special alloy of tungsten and metal oxides.
These electrodes have been specially designed for use in conjunction with Lampert fine welding equipment. The electrodes have excellent welding properties, but are hard and brittle.
If the electrode is bent, for example after it has caught on the workpiece and is then "broken off", splitting can occur.
The extreme temperature differences between the electrode tip and the electrode shaft that occur during welding also create large mechanical stresses in the electrode. Therefore, it cannot be ruled out that breakage or splitting (splitting) of the electrode may occur in isolated cases.
