TECNA 6023F 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 TECNA 6023F pairs a 40 kVA medium-frequency DC (MFDC / inverter) transformer with air-operated, linear-action actuation in a press-type spot welder configuration. The 6023F 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. 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.
