Abstract
A first electrode with a first clamping surface and a second electrode with a second clamping surface are moveable towards and away from each other during working cycles of the apparatus. The first and second clamping surfaces face each other and serve to securely clamp a workpiece to be welded and to supply an electrical current required for this operation. The second clamping surface of the second electrode is larger than the first clamping surface of the first electrode, and radial displacing members are provided to displace the second electrode with respect to the first electrode between successive working cycles. This is necessary, particularly during welding or soldering series of small articles, in order to reduce the frequency of wear due to heat accumulation and to reduce the need to frequently exchange the electrodes or electrode inserts carrying the clamping surfaces, which exchange is caused by the heat accumulation. Consequently, different surface sections of the larger second clamping surface of the second electrode face the first clamping surface of the first electrode during successive working cycles.
