Model 3411 Rocker Arm Spot Welder  
  Features - 3417 Specifications  
 
  • Air operated rocker arm welding machine with microprocessor welding control unit TE90.
  • Arms adjustable in length according to the Job to be carried out.
  • Chrome-copper electrode holders for long life and heavy duty service, designed for straight and angled fitting.
  • Adjustable electrode stroke to have the maximum working rate.
  • Epoxy coated, water-cooled transformer.
  • Water-cooled arms, electrode holders and electrodes.
  • Synchronous SCR contactor insulated from cooling water circuit.
  • Double effect air operated lubrication free cylinder, eliminates oil mist.
  • Electrode force adjustment with air filter reducer with gauge, with semi-automatic drainage system.
  • Electrode speed control valves, shock absorber for end of stroke and air discharge silencers.
  • Two-stage electric foot switch, that besides its normal use in automatic and single spot mode, allows the operator to bring the pieces together and to weld them only when correctly positioned.
  • Prearrangement for the connection of a second electric two-stage foot switching system 70284. The addition of the second foot switch allows to recall two different adjustments of time and current, required when different kinds of welding are to be performed on the same piece.
  • Single and automatic repeat modes.
