TECNA 6128NX Press-Type Spot/Projection Welder — 160 kVA Air-Operated MFDC / Inverter (480 V)

Description

The TECNA 6128NX is a medium-frequency direct-current (MFDC) inverter spot/projection welding machine pairing a 160 kVA (50% duty) transformer with linear-action, air-operated press actuation. Welding current is rectified and supplied at 1000 Hz, giving low line draw and balanced three-phase loading compared with single-phase AC machines. Standard electrode force is 1,654 lbs at 6 bar; the optional higher-force cylinder (Art. 6135) raises maximum electrode force to 2,792 lbs. The 6128NX offers a 21.26 in. electrode throat depth and a 16.22 in. projection-plate throat depth for both spot and projection work, with a 0–80 mm adjustable retraction stroke. Transformer, electrode holders, and electrodes are water-cooled for extended duty cycles.

Features

• 160 kVA (50% duty) MFDC inverter with 1000 Hz rectified DC output and water-cooled windings.
