TECNA 4660N rocker arm spot welder — 35 kVA, air-operated, single-phase AC. Maximum welding current of 17,500 amps, maximum electrode force of 955 lbs, and maximum throat depth of 23.62 in. with adjustable arms, stroke, and throat. Te101 microprocessor control.
The TECNA 4660N pairs a 35 kVA single-phase AC transformer with air-operated actuation. The 4660N provides a maximum welding current of 17,500 amps, a maximum electrode force of 955 lbs, and a maximum throat depth of 23.62 in. Arm length, electrode stroke, and throat depth are all independently adjustable to accommodate varied part geometries. A water-cooled, epoxy-resin-coated transformer supports extended duty cycles. The standard TE101 microprocessor weld control is front-mounted for real-time parameter viewing. Within the 4660-series, the 4660N is the entry 35 kVA model with a 23.62-in. maximum throat and 955 lbs of maximum electrode force; the 4661N extends throat depth to 31.50 in. at a reduced 584-lb force, while the 4662N increases power to 50 kVA.
Also listed as 4660NX (US-configured version).
