Projection Welding Machine

We are offering Three Phase Secondary-current Rectifier Spot & projection Welding Machine. The secondary of transtormer is a direct current return routine, so the transformer has very small inductance,compared with the similar family of spot welding machines,its power factor is much higher. Direct current heating can avoid energy loss caused by the decreasing of AC amplitude ,and also prevent sparking as of over current at peak value. It's suitable for welding multi-layers steel sheet.
