Automatic Seam Welder, Direct Current (DC) Inverter Type

The automatic seam welder (direct current (DC) inverter type) carries out automatic welding, making it suitable for large-scale production operations for manufacturing things like solar water heaters, sink fuel tanks, pipelines, gas tanks, machine enclosures, and so on.

Features
  • Two welding drive rolls with silver bearing helps to achieve consistent electrical conductivity and reduced friction to increase its production efficiency.
  • Corrections on bevel gears ensure the good leak tightness of welding parts. Breakdown or puncture of welding components can be prevented and wear-resistant welding wheel can maintain high-speed welding.
  • A resistance welding control system can help you adjust current frequency, pulse duration, current magnitude.
  • The T1 pure copper welding transformer has minimized no-load loss, strong output power, good insulating property for long service life.
  • High Si content electrical steel sheet, resin vacuum casting, water-cooled secondary connection cable
  • A two-way temperature regulating valve serves as an integral overload relief valve to prevent against transformer damage because of high temperature.
