High Frequency Direct Current Coil Nail Welding Machines

We are prominent manufacturer, supplier and exporter of High Frequency Direct Current Coil Nail Welding Machines in Tanghe, Henan, China.

1. May realize high-speed welding;
2. Eliminate the magnetic bias specific to old type of welding power, with stable operation;
3. High-efficiency and energy conservation, reducing cost;
4. Easy replacing and fast installation.

During power welding, fast heating is used to melt metals and gain temperature balance with fast cooling. And cooling time is adjusted by changing duty cycle to cooling time and repeat the cooling, to measure metal melting and not damaging of welding wire. Thus, the welding of common nail will not leave burn mark and the wire will become soft after welding, with firm welding joint. The solder joint size and shape are consistent with each other. The spark, splashing and coating burning is quite small during hot galvanized nail. The welding wheel life is twice of that of common welding power.
