TECNA 6012 rocker arm spot welder — 25 kVA, air-operated, MFDC / inverter. Maximum welding current of 12,000 amps, maximum electrode force of 539 lbs, and maximum throat depth of 21.65 in. with adjustable arms, stroke, and throat. Intuitive potentiometer-based control.
The TECNA 6012 pairs a 25 kVA MFDC / inverter transformer with air-operated actuation. The 6012 provides a maximum welding current of 12,000 amps, a maximum electrode force of 539 lbs, and a maximum throat depth of 21.65 in. Arm length, electrode stroke, and throat depth are all independently adjustable to accommodate varied part geometries. TECNA MFDC inverter technology delivers weld-to-weld repeatability and more efficient energy use than comparable single-phase AC welders. An intuitive potentiometer-based control provides simple manual adjustment of time and current parameters. Within the 6010-6013 family, the 6012 is the air-operated counterpart of the 6010, delivering identical 25 kVA power and 12,000-amp maximum current through pneumatic actuation for higher-tempo production.
