  welder photoMAIN WELDER FEATURES
bullet Cylinder with chrome plated stem for heavy duty works and long life; adjustable anti-rotation device.
bullet Lubrication free pneumatic components to eliminates oil mist and to protect the environment.
bullet Double-stroke cylinder with key control.
bullet Built-in compressed air filter unit.
bullet Compressed air disconnecting device.
bullet Water-cooled transformer, plates, electrode-holders and electrodes.
bullet Transformer with epoxy resin coated windings.
bullet Electrodes speed control valves, shock absorber for end of stroke and air discharge silencers assuring the minimum noise.
bullet Two stage electric foot control for clamping and welding pieces only if correctly positioned.
bullet Pre-setting for additional double stage electric foot connection for the direct recalling of welding program no.2.
bulletTE180 microprocessor control unit. Phase shift welding current adjustment. Synchronous SCR contactor insulated from cooling water circuit with protection thermostat.
bullet 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).
bullet Emergency push-button to stop the machine immediately.
