The DN multi spot welder with high secondary volts is engineered for high precision through digital control. With optimized welding results, it can be widely used for electro-soldering, heat tempering, and annealing.

Features
  • Digital setting and display of all operating parameters like weld voltage, power setting, etc.
  • In-memory data storage to prevent accidental data loss.
  • Voltage fluctuations are monitored to prevent damage to data.
  • Adjustable stroke air cylinder and speed control valves to control ram movement up and down.
  • Resistance welding transformer delivers a strong electrical current. The water-cooled welding transformer can deliver power at high efficiency to reduce the energy loss using silicon steel cores.
  • 40 sets of welding parameters are under microprocessor precision control.
  • Error management is adopted for general warnings and major faults through the appearance of error messages.
