D(T)Z single/three phase secondary-current rectifier spot&projection welding machine

This machine is a new developed machine that works directly on object with DC.

1.The secondary of transformer is a direct currentreturn routine,so the transformer has very small inductance ,compared with thesimilar family of spot welding machines,its power factor is much higher.

2.Direct current heating can avoid energy losscaused by the decreasing of AC amplitude,and also prevent sparking as of overcurrent at peak value .compared with other similar products,it requires lessrated capacity and also high welding quality when welding the same thicknessmaterials.

3.NO alternation electromagnetic force between thetwo polar arwis can ensure steady polar arwis can ensure steady polar pressure.

4.Balance three-phrase has no effect on electricnet,Hence the energy saving substantially.

5.Besides welding general materials,it’s suitablefor welding multi-layers steel sheet.Over 4MM+4mm aluminum product.and aluminumalloy.Achieving good welding result.
