TECNA 4661N rocker arm spot welder — 35 kVA, air-operated, single-phase AC. Maximum welding current of 14,000 amps, maximum electrode force of 584 lbs, and maximum throat depth of 31.5 in. with adjustable arms, stroke, and throat. Te101 microprocessor control.
The TECNA 4661N pairs a 35 kVA single-phase AC transformer with air-operated actuation. The 4661N provides a maximum welding current of 14,000 amps, a maximum electrode force of 584 lbs, and a maximum throat depth of 31.5 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 4661N extends maximum throat depth to 31.50 in. — the longest reach in the 4660-series — with the same 35 kVA rating as the 4660N and a reduced 584-lb maximum electrode force.
Also listed as 4661NX (US-configured version).
