Product Description

DR Series Capacitance Discharge Spot Welding Machine

No need of current-limiting resistor reduces heat resource.
No black spot n welding point,free of polish. 
A built-in voltage regulator ensures constant output voltage. The welding consistency is good. 
Full digital control with high precision. 
Components and parts from world famous factories ensure quality. 
The welder is easy to operation and free of complicate educational procedure. The welding effect is perfect. 
Primary welding material:stainless steel, brass,copper alloy, and duralumin. 
Suitable for electric appliance,watch chain,jewelry,stainless tableware,and hardware manufactruers.
 In this resistance welding process, a bank of capacitors is charged to a pre-set voltage and then discharged through a pulse transformer. Very high current is passed in very short time resulting in fantastic projection welding quality. As the machine requires power just for charging the bank of capacitors, the power (Kva) requirement is negligible as compared to any other process of resistance welding. This results in great saving of connected load as well as power usage. As the weld time is very less (ideally 3 to 12 milliseconds), there is negligible heating or blackening of welded components and water cooling for the electrodes is not required.

This technology is ideal for projections welding, dissimilar metal welding and thin sheet spot welding. Machine users requiring excellent aesthetics, high regard for power saving and consistency in projection welding should adopt this technology.
