With over-temperature protection device, once the temperature approach upper limit gauge, the welder can automatically stop working. This machine can suspend and link two different gas motive welding guns ,can use for welding two kinds of different work-pieces at the same time . The DN3 series suspended spot welding machine is used for welding various work-piece that the stationary welding machine is difficulty to welding .This machine's great characteristic could have been  suspended on  metal frame and can arbitrarily move and revolve on vertically or horizon tally direction so as to welding large weight and complex work-piece.

The new DN3 series suspended spot welding machine is provided  high,middle ,low class electric resistance welding controller ,it can be used for welding various kinds of low-carbon steel sheet ,alloy steel sheet ,layer-plating steel sheet ,stainless steel.

The suspended spot welding machine is widely applied in  industry of automobile ,agricultural machinery ,  motorcycle ,tractor , bicycle , aviation , household appliances ,electronic  ,metal mesh etc.
With digital controller , operator can adjust the weld time ,weld current ,weld pressure etc , and monitored and recorded all the weld processing
