Items 2121-2126 - Linear action spot and projection welders - 35-63 kVA MAIN WELDER FEATURES
  • Built-in compressed air filter unit.
  • Electrodes speed control valves, shock absorber for end of stroke and air discharge silencers assuring the minimum noise.
  • Lubrication free pneumatic components to eliminates oil mist and to protect the environment.
  • Cylinder with chrome plated stem for heavy duty works and long life; adjustable anti-rotation device.
  • Cylinder with double stroke with key control.
  • Water-cooled transformer, plates, electrode-holders and electrodes.
  • Transformer with epoxy resin coated windings.
  • TE180 microprocessor control unit. Phase shift welding current adjustment. Synchronous SCR contactor insulated from cooling water circuit with protection thermostat.
  • Two stage electric foot control for clamping and welding pieces only if correctly positioned. The foot control is standard on spot welder models only (on request on projection models).
  • Pre-setting for additional double stage electric foot connection for the direct recalling of welding program no.2 (not on welders equipped with option 2161).
  • Two-hand safety control with timer for maximum safety, and removable key selector, standard on all models. The push-buttons of the two hand control are standard on projection models only (on request on spot welder models).
