TECNA 3324 scissor-type suspended spot welding gun — 23 kVA, built-in TE300 timer. Adjustable arms 9.84–25.59 in.; max electrode force 602 lbs (268 daN) at 6 bar.
The TECNA 3324 is a suspended, air-operated scissor production spot welding gun with a built-in TE300 control unit. It pairs a 23 kVA (50% duty) single-phase AC transformer with an adjustable arm length of 9.84–25.59 in. (250–650 mm) and delivers a maximum electrode force of 602 lbs (268 daN) at 6 bar at the shortest arms. Electrodes, electrode holders, arms, transformer, and thyristor are fully water-cooled. The gun is suspended on a balancer for low-fatigue handling across its working envelope.
Standard TECNA configuration, built to specified voltage/frequency. US pre-configured builds available as 3324NX (standard cables) and 3324NX/LC (49 ft cables).
