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.

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 TE101
Adjustable electrode force; a microswitch starts the welding cycle when the desired pre-set value is reached
The foot pedal is adjustable in length


TE101 TECNA MICROPROCESSOR CONTROL UNIT:
