TECNA 6020FA 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. Te700 microprocessor control.
The TECNA 6020FA pairs a 40 kVA MFDC / inverter transformer with air-operated actuation. The 6020FA 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 TE700 advanced microprocessor control provides enhanced programmability for demanding production requirements. Within the 6020-series, the 6020FA shares the 6020F’s 40 kVA power, 15,200-amp maximum current, and 23.62-in. maximum throat; the FA variant replaces the TE751 control with an advanced TE700 microprocessor control for enhanced programmability.
