It is essential for tubular elements production to rapidly, consistently and firmly weld the heating alloy or connector tabs onto the terminal pins. DH-5 spot welding machine solve the welding problem between different types of heating alloys and terminal pins, connector tabs and terminal pins.

DH-5 discharge the large current stored in the capacitor rapidly through the electric switch circuit towards the welding transformer. The current is highly centralized at the welding point to heat up and melt the place quickly then weld it firmly. The surface of welded part won’t turn black but keep natural color because of its high resistance to oxidation. Welding power and working pressure could be easily adjusted and effectively locked for a long time once adjusted. DH-5 is suitable for mass production for its easy operating and uniformly welding advantages.
