#98283 - 400V 100A Responding to: ???'s previous message |
Dear Erik,
Thanks for your reply, isn't a weld basically a short? It looks that way to me. So, how will you maintain 400V? You are right Resistance weld is essentially a short. This 400V is not applied to electrodes. It is fed to welding transformer which drops the voltage down to 4 to 10 Volts. This 4 to 10 Volts is applied to electrodes [ short ]. The currents flowing are of the order of several ten thousand amps through this short. I am trying to develop a higher freqency power supply for feeding my welding transformers. The advantage of higher frequency is.. 1. Smaller transformer size and weight less core required. 2. Smaller cycle interval gives better heat control. 3. Suitable for welding small delicate parts. Thanks & Regards, Prahlad Purohit |
