Key Features of Capacitor Discharge Projection Welding Machines

• Large scale reduction in power [Kva] demand as compared to conventional resistance welding machines. For example 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.
• Negligibleÿblackening 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.
