Tecna Spot Welder – 25 kVA – with Pedal/Micro Processor Control – Tecna 4643
TECNA spot welders are designed to meet every need of spot welding. The new stationary ergonomic frame designed by TECNA helps to facilitate the operator’s work.
The control unit has been positioned frontally to allow the operator to view the welding data even during the working cycle.
The pneumatic commands and the compressed air pressure gauge have been placed at the top for easier adjustment and reading.
Features
- 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.
- Adjustable electrode force; a microswitch starts the welding cycle when the desired pre-set value is reached. The foot pedal is adjustable in length.

The TECNA TE101 is a microprocessor-based welding control.. The weld control is used to control the movement of the welder and the thyristor / silicon-controlled rectifier (SCR) that regulates the welding current. The working program followed by the TECNA TE101 is created through the 13 programming parameters available in the control. The TE 101 may be used for both manual and pneumatic-operated welders.
