  • 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.
  • 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.
