Items 8001-8009

- Linear action spot and projection welders - 35-80 kVA

MAIN WELDER FEATURES

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.
Double-stroke cylinder with key control.
Built-in compressed air filter unit.
Compressed air disconnecting device.
Water-cooled transformer, plates, electrode-holders and electrodes.
Transformer with epoxy resin coated windings.
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.
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.
