Year 2000 is a company that makes miniature electronic parts. A couple of years ago it started to develop a machine that could weld micro parts to serve the company&＃39;s precise needs. The "Precision-weld" PW-06 Spot Welding Machine is a compact size lead free device capable of handling the welding needs of very fine wires ranging 0. 025mm-0. 3mm. The product utilizes the principle of high temperature welding. Current flowing through the welding tip creates a high temperature to burn off the wire insulation, and then continues through the exposed wire and the metal base to weld the two together. Welding quality is assured by the patented pressure control mechanism and corresponding current recordings. The PW-06 can greatly reduce the training period of workers from weeks to just few hours. On the environmental side, no chemical solvent and insulation removal is needed, which also saves costs and labour. The device enjoys low voltage (<2. 5v) operations and low energy consumption.
