Capacitor Discharge Projection Welding Machines

We provide capacitor discharge projection welding machines along with we also provide welding process. 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 capacitor discharge projection welding machines 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.

• Large scale reduction in power (Kva) demand as compared to conventional resistance welding machines. For example our 10Kva CD projection welder can weld components, which are welded on 50 to 75 Kva conventional A.C. projection welder.
• No water-cooling required for electrodes due to very short weld times. Cost of manufacturing electrodes is reduced.
• Negligible blackening and distortion at weld joint. Excellent aesthetics. No mark on the other side of the weld.
• No effect of normal voltage fluctuation on weld quality. Machine will not discharge (weld) unless capacitors are charged to the pre-set voltage.
• It’s a three-phase machine and it can work on Generator set.
• Welding near heat sensitive parts is possible.
• Welding of similar and dissimilar metals possible.
• Installation and operating cost of the machine is very very less. The more you weld, the more you save.
