TECNA 6023FA press-type spot welder — 40 kVA, air-operated, MFDC / inverter. Maximum short-circuit current of 19,000 amps with 674 lbs of electrode force at minimum throat depth. The FA variant ships with the TE700 microprocessor control unit (upgraded from the standard TE751).
The TECNA 6023FA pairs a 40 kVA medium-frequency DC (MFDC / inverter) transformer with air-operated, linear-action actuation in a press-type spot welder configuration. The 6023FA provides a maximum welding power of 85 kVA and a maximum short-circuit current of 19,000 amps. Maximum electrode force is 674 lbs at its 19.69 in. throat depth, with a 2.36 in. (60 mm) double stroke. The FA variant designation indicates this welder ships with the TE700 microprocessor weld control in place of the standard TE751 found on the F variant. MFDC inverter technology offers significant advantages over single-phase AC, including faster weld cycles, balanced three-phase mains loading, lower energy consumption, and improved weld quality on coated and dissimilar materials. A water-cooled transformer, electrode holders, and electrodes support extended duty cycles.
