The machine uses a small impact on the grid three-phase power grid capacity requirements with respect to the same capacity of a single-phase welder much lower. Welding transformer with a center-tapped secondary use of six-phase half-wave rectifier seamless welding offers small ripple factor and no zero crossing of the DC power electron beam welding, weld quality in the welding can be fully guaranteed. WD-KD3: digital circuit welding, copper welding DIP adjusted, three sections of discharge, for special materials can be used for preheating, welding, plastic or tempered, to solve the multi-Weld projection welding current shunt caused due , sealing off and other defects, especially for high-carbon steel, special laminated metal plate can be welded with ease, when calls voltage fluctuations automatic welding current compensation. _ _ Welding copper welding welding Huashi Huashi by Huizhou City Welding Equipment Co.
