a) The key point of design is the welding power source. Since area of the wire after welding is large, the three-phase secondary rectifying power source is adopted to ensure the stability of welding. It can output direct current to weld.

b) The slide way is controlled by the feeding cylinder. The speed of feeding is adjustable while the feeding length could be adjusted randomly through setting the magnet switch.

c) It contains 14 sets of material feeding plate at most. They could be used randomly according to the requirement of product.

d) Adopt digital PLC control wiring. It is equipped with double functions of automatic protection and correcting. I
