1.Series model:DN3-100,125,160,200,250., 2.Light and compact design in order to achieve the best maneuverability - details see: https://www.machineto.com/200kva-portable-spot-welding-transformer-10142310

Introduction:

DN3 series portable spot welder supports double welding guns and double welding criterion . It output an invariableness current and control the welding guns with solenoid valve. It is employed when the work piece can't be welded on the standard immovable spot welder. It is widely applied in manufacture of automobile and manufacture domestic electric appliance.

The Si steel pieces are imported ones. The winding of transformer adopt vacuum casting technology. It is small size, light weight, durable welding-ability and double gas circuit system. The gas pressure of Each circuit is separated. The pneumatic spare part is adopted of the most advanced one in the world. It’s low noisy, good stable performance.

The series has :DN3-100,125,160,200,250.

Note: Pls refer to instruction manual for details.
