4646 - Tecna 4646 20kVA Rocker Arm Spot Welder with TE-101 Control

Reliable Spot Welding for Fabrication Shops

Take your sheet metal fabrication to the next level with the Tecna Model 4646, a 20 kVA rocker arm spot welder built for versatility and ease of use. Whether you are welding mild steel enclosures, repairing auto body panels, or fabricating HVAC components, this machine provides the power and reach you need. One of the biggest challenges in spot welding is fitting the part into the machine; the Tecna 4646 solves this with fully adjustable arms that can extend up to 22 inches deep. This extra clearance means you can weld the center of large panels or reach around obstacles without struggling or repositioning the machine.

Gone are the days of guessing your settings with analog dials. The included TE-101 digital weld control puts you in the driver's seat, allowing you to dial in the exact weld time and power needed for your specific material thickness. This results in clean, strong nuggets every time with minimal surface indentation. To keep you welding longer, the machine features water-cooled arms that prevent the tips from overheating and mushrooming, saving you time on maintenance and tip dressing. The two-stage foot pedal is a favorite feature among operators: press halfway to clamp your part and check your fit-up, then press all the way down to weld. It’s safer, more accurate, and reduces wasted material. Backed by a one-year warranty and Hydro approval, the Tecna 4646 is a dependable investment for any serious metalworking shop.
