DN Bench Type Spot/Projection Welder

DN Bench Type Spot/Projection Welder

The DN bench type spot/projection welder is widely used for numerous welding process and features reduced installation costs. A standard spot weld with a current path directly through the workpiece between opposing electrodes can be achieved using this resistance welding machine. It operates with lead-free soldering technology, making it an eco-friendly joining method. In compliance with ROHS/SGS standards, this welder delivers excellent temperature tolerance, making it suitable for strategically placed small spot welds.

Features
  • Solid structure with high strength. High structural rigidity of the welding machine arms, holders and inline bearings can insure positive alignment, minimal deflection and reduced friction.
  • Fast electrode response for quick welding. Electrodes are equipped with speed control valves, shock absorber for end of stroke and air discharge silencers to minimize the noise.
  • Insulation protection for safety. Low-friction air cylinder is insulated from the electrode body to ensure heavy duty performance and a long working lifetime.
  • Welding power sources maximizes energy savings. Water-cooled resistance-welding transformers and silicon controlled rectifiers for checking the correct diode clamping force.
