  • Welding appearance: Very less hot warp and oxidation save the processing in follow-up steps.
  • Stability: Less soldering tolerance conforms to JIS vehicle specifications.
  • Economy: The consuming parts such as copper-alloy electrode is very less, and power consumption is very less. The operation cost is low.
  • The machine is adjustable to fit either thin or thick workpiece. Both continuous type and pulse type of electricity discharge are available.
  • Free of soldering scars: Save a lot of time on polishing, soil-patching and coating on next processing steps.
  • High maneuverability: The machine can be operated soon after it is started. Any ordinary technician can operate the machine.
  • The pneu & hyd. component such as the cylinder tube is imported form Japan, which is seamless tube , and mandrel both with chrome-plated.
  • The inner of secondary transformer which adopted forging brass plate and installed cooling water hole to reduce the electric resistance & advance the efficiency, especially the transformer is treated annealing treatment which can be stabled the transient output electric current.
  • The hydraulic system are concentrated and the oil cooler attached which assured the hydraulic oil in normality for long servicing period, reduced the cost and long servicing life.
  • The electronic components are adopted from importation. Adopted the push button panel form imported to control the electrode discharge and the current required for the workpiece can be adjusted randomly in.
  • The high precision digital key switch and the synchronous IC controlling circuit etc., and adopted no contact IC controlling & synchronous PC board, high precision of electric welding and long servicing life.
  • Adopted geared displacement pump and stepless variable speed hyd motor from imported, the welding speed can be adjusted randomly, within the scope of our needs which could make the pressure stable and uniform.
