Title:
SPOT WELDING MACHINE CAPABLE OF DIRECTLY WELDING ENAMELLED WIRES
Document Type and Number:
WIPO Patent Application WO/2002/102540
Kind Code:
A1
Abstract:
The invention relates to a spot welding machine provided for electronic industries, micro-electronic industries, particularly, it adapts to directly weld enamelled wires, bare wires of which the diameter is in the range of 0.02 mm - 0.80 mm or corresponding thin sheet metal and strip metal. The present spot welding machine consists of a welding head, a main unit serving to adjust and control a power source, and a machine head. Since the tips of the welding head is ohmic contact with some stress, which formed a particular configuration, and the circuits of the main unit provide the suitable current, it is not necessary to remove the insulating layer by man before welding, and the spot joint is firm, the machine is simple to operate and is timesaving.
