TECNA 6020F rocker arm spot welder — 40 kVA, air-operated, MFDC / inverter. Maximum welding current of 15,200 amps, maximum electrode force of 955 lbs, and maximum throat depth of 23.62 in. with adjustable arms, stroke, and throat. Te751 microprocessor control.
The TECNA 6020F pairs a 40 kVA MFDC / inverter transformer with air-operated actuation. The 6020F provides a maximum welding current of 15,200 amps, a maximum electrode force of 955 lbs, and a maximum throat depth of 23.62 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. The TE751 microprocessor control provides a widescreen display for monitoring weld parameters during operation. Within the 6020-series, the 6020F and 6021F share identical 40 kVA power and 15,200-amp maximum current; the 6021F extends maximum throat depth to 31.50 in. for deeper-reach applications, while the 6020F’s shorter 23.62-in. throat maintains the 955-lb maximum electrode force.
