TECNA 6074-8039 Press-Type Spot Welder — 56 kVA Air-Operated MFDC / Inverter (Throat-Extension Option 8039, 35.43 in. (900 mm))

Description

The TECNA 6074-8039 pairs a 56 kVA medium-frequency (MFDC / inverter) transformer with air-operated actuation in a press-type spot 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 674 lbs (300 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. 8039 throat-extension option, giving an electrode throat depth of 35.43 in. (900 mm).

Features
