Single phase welders

8214MAIN WELDER FEATURES

  • Modular design in mechanical structure, arms, brackets, cylinders.
  • Cylinder with chrome plated stem for heavy duty works and long life; adjustable anti-rotation device.
  • Lubrication free pneumatic components to eliminates oil mist and to protect the environment.
  • Head descent without pressure for set up and service.
  • Double-stroke cylinder withkey control.
  • Built-in compressed air filter unit and tank.
  • Compressed air disconnecting device.
  • Electrodes speed control valves, shock absorber for end of stroke and air discharge silencers assuring the minimum noise.
  • Two stage electric foot control for clamping and welding pieces only if correctly positioned.
  • Pre-setting for additional double stage electric foot connection for the direct recalling of welding program no.2.
  • Water-cooled transformer, plates, electrode-holders and electrodes; transformer with epoxy resin coated windings.
  • TE550 costant current microprocessor control unit.
  • Synchronous SCR contactor insulated from cooling water circuit with protection thermostat.
  • Standard on all models: two-hand safety control with timer assuring the best safety, and removable key selector. The two-hand control push-buttons are standard on projection models only (thay are available on request on spot welder models).

OPTIONS

  • 8230 - Valve to stop the flow of the water cooling when the machine is off and flow switch which makes the welder stop if the cooling water does not circulate.
  • 8232 - Rotary selector for recalling the welding programs.
  • 8234 - Double stroke control device with pneumatic foot instead of key one. To be used only for spot welding when the work necessarily requires it.
  • 8235 - Cylinder 1242 daN (diameter 125 mm double stage) total stroke 100 mm (only on items 8201D..09D and 8214D).
  • 8236 - Adjustable double stroke for cylinder 736 daN (standard).
  • 8237 - Adjustable double stroke for cylinder 1242 daN (option 8235).
  • 8238 - Low force squeeze for cylinder 736 daN (standard).
  • 8239 - Low force squeeze for cylinder 1242 daN (option 8235).
  • 8240 - Proportional valve.
