Product Details

Tecna has long been considered the international leader in Spot Welding. Tena's range of Pedestal Spot Welders are Italian made to the highest quality standards and are serviced and distributed in Australia by the highly regarding UniMIg team. Tena's range of Spot Welders can all be customised to ensure maximum efficiency and reliability.

- Arms adjustable in length allowing a better working flexibility.
- Chrome-copper electrode-holders for long life and heavy duty service, designed for straight and angled fitting.
- Adjustable electrode stroke.
- Epoxy resin coated transformer.
- Water-cooled transformer, arms and electrodes.
- Microprocessor control unit TECNA TE90.
- The air operated lubrication free cylinder eliminates oil mist.
- Electrode force adjustment with air filter reducer with gauge.
- Semi-automatic drainage system.
- Electrode speed control valves, shock absorber for cylinder's end of stroke and air discharge silencers.
- Two-stage electric foot pedal, that besides its normal use in automatic and single spot mode, allows the operator to bring the pieces together and to weld them only when correctly positioned.
- Pre-arrangement for the connection of a second electric two-stage foot pedal item 70284.
- The addition of the second foot pedal allows to recall two different adjustments of time- current. This function is helpful when different kinds of welding are to be performed on the same piece.
