TECNA Rocker Arm Spot Welders FOR SALE

Foot and Air (Pneumatic) Operated Rocker Welders

TECNA rocker arm spot welders are reliable, versatile stationary resistance spot welders designed for low- to moderate-production welding applications. These machines are ideal for welding sheet metal and fabricated components, with welding capacities up to two thicknesses of 1/8″ steel, depending on the model and application. Available in both foot-operated and pneumatic configurations, TECNA rocker arm spot welders are designed for operator comfort, ease of use, and consistent weld quality.

TECNA’s ergonomic stationary frame helps improve operator comfort and productivity. The weld control is positioned at the front of the machine, allowing operators to view welding parameters and data throughout the welding cycle easily. On pneumatic models, air controls and the compressed-air pressure gauge are conveniently positioned at the top of the machine for quick adjustment and easy monitoring. TECNA rocker arm spot welders are available with single-phase AC or three-phase MFDC power supplies, providing options for a wide range of resistance welding requirements.

TECNA Welders In Stock and Ready to Ship

Weld Systems Integrators (WSI) is a stocking master distributor of TECNA industrial resistance welders and tool balancers. We stock, sell, repair, and support TECNA resistance welding equipment, maintaining an IN-STOCK inventory at our Warrensville Heights, Ohio facility, providing manufacturers with quick access to new welding equipment without extended lead times.

For applications requiring higher duty cycles or additional welding force, TECNA also offers pneumatic press-type spot and projection welders, including single-phase AC, three-phase MFDC, and three-phase DC models.

How Do I Choose the Right TECNA Rocker Arm Spot Welder?

TECNA Rocker Welder Selection Guide

Selecting the right TECNA rocker arm spot welder depends on the material being welded, material thickness, required weld force, throat depth, electrode configuration, production requirements, and available electrical power. The welder must provide enough welding current and electrode force to consistently produce a strong, repeatable weld for your specific application.

TECNA offers rocker arm spot welders ranging from approximately 16 to 50 kVA, including single-phase and inverter models, with multiple arm and electrode configurations.

Key factors to consider include:

  • Material and Thickness: The type, thickness, and number of metal sheets being welded determine the welding current and electrode force required.
  • Welder Power (kVA): TECNA rocker arm welders are available in multiple power ratings. Higher-capacity applications may require a larger transformer and greater available welding current.
  • Foot vs. Pneumatic Operation: Foot-operated models are a simple, economical choice for lower-production applications. Pneumatic models provide greater and more repeatable electrode force and are generally better suited for higher-production applications.
  • Throat Depth: Choose an arm length that allows the electrodes to reach the required weld location. Depending on the model, TECNA offers different throat depths; for example, the 4640N provides up to 550 mm, while the 4644N provides up to 700 mm.
  • Electrode Force: Adequate electrode force is critical for producing consistent resistance welds. Available force varies significantly by model; heavier-duty pneumatic machines can provide substantially more force than smaller foot-operated units.
  • Production Requirements: Consider the number of welds per part, welds per hour, duty cycle, part handling, and required weld consistency when sizing the machine.
  • Available Utilities: Verify that your facility has the required electrical service, cooling water, and, for pneumatic models, compressed air.

Not sure which TECNA rocker arm welder you need? Provide Weld Systems Integrators with your material type, material thickness, number of layers, part dimensions, weld location, and desired production rate. WSI can help determine the appropriate TECNA model, kVA rating, electrode force, arm configuration, and welding control for your application.
