TECNA 3680Si industrial welding station — a wheeled MFDC inverter spot welding system with the patented 8692 C-gun (15,500 A, 1,382 lbs force), motorized suspension arm, Bowden balancer retractor, and SMART weld-by-weld control.
The TECNA 3680Si is a complete industrial spot welding station built around a three-phase MFDC inverter and the patented 8692 C-gun. It delivers 15,500 amps of welding current and up to 1,382 lbs (615 daN) of electrode force at 8 bar, with TECNA SMART MODE automatically adjusting welding parameters weld by weld. The wheeled console integrates a motorized suspension arm, a Bowden balancer retractor, and a 6.6 gallon (25 L) water-cooling tank, and is predisposed for robot/cobot integration.
