SINGLE-PHASE, RESISTANCE WELDERS - 80 TO 315kVA AT 50% 

Welder photoMAIN WELDER FEATURES
bullet Modular design of mechanical structure, arms, brackets, cylinders.
bullet Cylinder with chrome plated stem for heavy duty works and long life; adjustable anti-rotation device.
bullet Lubrication free pneumatic components to eliminate oil mist and to protect the environment.
bullet Head descent without pressure for set up and service.
bullet Double-stroke cylinder with key control.
bullet Built-in compressed air filter unit and tank. Compressed air disconnection device.
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. Standard on spot welders, on request on projection welders.
bullet Preconnected for additional double stage electric foot control for the direct recalling of welding program no.2 (not on units equipped with rotary selector recall).
bullet Water-cooled transformer, plates, electrode-holders and electrodes; transformer with epoxy resin coated windings.
bullet Synchronous SCR contactor insulated from the 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.
bullet Digital welding control with welding current direct reading: TE185 direct current standard, TE250-TE500-TE1000 on request.
