Items 2121-2126

- Linear action spot and projection welders - 35-63 kVA

MAIN WELDER FEATURES

Built-in compressed air filter unit.
Electrodes speed control valves, shock absorber for end of stroke and air discharge silencers assuring the minimum noise.
Lubrication free pneumatic components to eliminates oil mist and to protect the environment.
Cylinder with chrome plated stem for heavy duty works and long life; adjustable anti-rotation device.
Cylinder with double stroke with key control.
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.
Two stage electric foot control for clamping and welding pieces only if correctly positioned. The foot control is standard on spot welder models only (on request on projection models).
Pre-setting for additional double stage electric foot connection for the direct recalling of welding program no.2 (not on welders equipped with option 2161).
Two-hand safety control with timer for maximum safety, and removable key selector, standard on all models. The push-buttons of the two hand control are standard on projection models only (on request on spot welder models).
