MAIN 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 (not on units equipped with option 8232).
- 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.
- 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).
- Emergency push-button to stop the machine immediately.

* Different voltages and frequencies on request
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.
- 8231 - Welding adaptive control unit type TE250 item 1311.
- 8232 - Rotary selector for recalling the welding programs.
- 8233 - Constant current welding control unit item TE185.
- 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 8201-2-3-4-5-6-7-8-9).
