The DR series capacitor energy storage welding machine produced by Zhongbang Welding Machine is a capacitive spot welding machine model that does not require charging current-limiting resistors

The use of soft-start mode all-digital integrated circuit to control constant current charging is faster and more stable.

No need to charge the current-limiting resistor to avoid the heating of the current-limiting resistor and lead to energy waste. It saves 40% of electricity compared with ordinary capacitive spot welders.

Imported famous brand emergency charging and discharging capacitors are adopted, with stable capacity and long service life.

Digital charging voltage display, setting charging voltage is more accurate \ more intuitive

It has a wide range of uses, especially suitable for the welding of aluminum\copper\stainless steel\alloy\tungsten and other metal plates with good thermal conductivity\wire\wire and welding of dissimilar metals.
