DC Electric Resistance Welding Machine

DC electric resistance welding machines use the heat generated by the contact resistance between the electrodes to melt metal, and thus, achieve welding of copper, aluminum, stainless steel and other metals. It has a great stability with a 1000HZ working frequency and 1ms response time, making it applicable for use in hardware products, automobiles, and electric appliances.

Compared to an AC resistance spot welding machine, the DC electric resistance welding machine has the following prominent features:
1. Larger response speed and better stability.
2. Larger welding speed.
3. Better energy-saving ability.
