THREE PHASE RESISTANCE WELDERS

SPOT AND PROJECTION WELDING WITH DIRECT CURRENT

DC air operated spot welders, three phase supply, designed for spot and projection welding. Suitable for both spot and projection welding , PPN3FCC models fully meet the mass production toughest industrial applications. Thanks to their features, they represent the ideal solution for resistance spot welding of Aluminium and other material not easily weldable by conventional resistance equipment. Equipped with microprocessor control, concomitant safety side buttons and solenoid valve, upon request, they can be supplied with special controls and configurations.

Direct current advantages

  • High quality joints
  • Large power for projection welding
  • Large power for welding with increased arm lengths
  • The presence of magnetic materials between the arms does not affect welding
  • Long electrode life
  • Highest efficiency
  • Reduced welding time

Other characteristics

  • Platens gap is easily and quickly adjustable without any intervention on the secondary circuit (patent pending)
  • Upper head low friction linear driving system for very precise welding
  • Manual valve for upper head descent without pressure for cleaning, centering and ordinary maintenance of the electrodes
  • Solenoid valve to stop water circulation whenever the machine is switched off from the mains supply
  • Suitable for applications requiring high welding power, such as mesh welding
  • High welding quality and process reliability
    Synchronous ignition SCR group with phase shift welding current adjustment to eliminate initial transient
  • Thermostatic protection on the SCR group
  • Six phase rectifier bridge with diodes protected against overheating and overvoltage
