TECNA 6075A-8031 press-type spot/projection welder — 56 kVA, air-operated, MFDC / inverter fitted with the Art. 8031 throat-extension option. Maximum short-circuit current of 25 kA with 1,056 lbs (470 daN) of electrode force at 6 bar. Electrode throat depth of 19.69 in. (500 mm) and projection plate throat of 14.96 in. (380 mm). Ships with the TE700 microprocessor control (upgraded from the standard TE751).
The TECNA 6075A-8031 pairs a 56 kVA medium-frequency (MFDC / inverter) transformer with air-operated actuation in a press-type spot/projection welder configuration. TECNA inverter technology delivers higher welding quality and precision, more efficient use of electricity, a more compact build, and lower impedance loss than single-phase AC. It provides a maximum welding power of 200 kVA and a maximum short-circuit current of 25 kA, with 1,056 lbs (470 daN) of electrode force at 6 bar. A water-cooled transformer, plates, electrode holders, and electrodes with epoxy resin-coated windings support extended duty cycles. In this configuration the machine carries the Art. 8031 throat-extension option, giving an electrode throat depth of 19.69 in. (500 mm) and a projection plate throat depth of 14.96 in. (380 mm).
