Welding without the tungsten electrode. To join two parts with this welding program, one part of the workpiece is connected to the anode (black cable) the other part to the negative pole (red cable).
When both parts are properly connected, they are brought into contact in the area where they should be joined. Then the welding impulse is triggered with the foot pedal, welding both parts together at the place they touched.

The result: Contact welding - also called resistance welding - offers completely new applications for any kind of fixing joints, especially for orthodontic welding jobs.
