TECNA 4668NX Press-Type Spot Welder — 50 kVA Air-Operated Single-Phase AC

TECNA 4668NX press-type spot welder — 50 kVA, air-operated, single-phase AC. Maximum short-circuit current of 16,500 amps with 674 lbs of maximum electrode force. Fixed 19.69 in. throat depth. Standard TE101 microprocessor control.

Description

The TECNA 4668NX pairs a 50 kVA single-phase AC transformer with air-operated, linear-action actuation in a press-type spot welder configuration. The 4668NX provides a maximum short-circuit current of 16,500 amps, with maximum electrode force of 674 lbs. The thermal current rating at 100% duty cycle is 5,700 amps. A water-cooled transformer, electrode holders, and electrodes support extended duty cycles, with epoxy resin-coated windings for long service life. The fixed 19.69 in. throat depth accommodates a wide range of workpiece geometries. The NX designation indicates the US-market configuration. The standard TE101 microprocessor weld control is included; the TE550 microprocessor weld control is available as an upgrade option for advanced parameters and USB interface.
