Press Welders for Spot and Projection Welding
WSI and TECNA Press-Type Resistance Welders FOR SALE
Press-Type Spot and Projection Welders for Resistance Welding Applications
A press-type resistance welder is a spot or projection welding machine that applies electrode force in a straight vertical motion. Unlike rocker arm welders, the upper electrode moves vertically toward a fixed lower electrode, providing consistent alignment and force throughout the weld cycle.
Press-type resistance welders are used for spot welding, projection welding, fastener welding, nut welding, and stud welding applications requiring precise vertical electrode force. Unlike rocker arm welders, press welders move the upper electrode vertically in a straight line toward a fixed lower electrode, providing consistent alignment and force throughout the weld cycle.
Weld Systems Integrators offers WSI and TECNA press-type spot and projection welders in standard and custom configurations. Available power supplies include AC, MFDC, DC, and capacitor discharge (CD), depending on the machine and application. WSI and TECNA press welders can be equipped with platens or weld arms. Projection welding utilizes platens with T-slots for mounting part fixtures and tooling. Spot welding uses a weld arm configuration. Platens and weld arms are most often made of copper or class 2 copper alloy.

Frequently Asked Questions (FAQ) – Press-Type Welders
What is a press-type resistance welder?
A press-type resistance welder is a spot or projection welding machine that applies electrode force in a straight vertical motion. The upper electrode or welding head moves vertically toward a fixed lower electrode or platen, providing precise alignment and consistent weld force. Press-type welders are commonly used for projection welding, nut welding, stud welding, fastener welding, high-force applications, and applications requiring specialized tooling.
Press-type resistance welders are commonly used for:
- Projection welding
- Resistance spot welding
- Nut welding
- Stud welding
- Fastener welding
- High electrode-force applications
- Applications requiring specialized tooling
- Applications requiring frequent tooling changes
- Automated resistance welding systems
What's the difference between a press welder and a rocker arm welder?
A press welder moves the upper electrode vertically in a straight line, while a rocker arm welder moves the upper electrode through an arc. Press-type welders are generally preferred for projection welding, fastener welding, high electrode force, specialized tooling, and applications requiring precise electrode alignment. Rocker arm welders are commonly used for general-purpose resistance spot welding where greater throat access is required.

How do I choose a press-type welder?
Choosing the correct press-type welder depends on the material, part geometry, required weld current, electrode force, throat depth, tooling requirements, production rate, and available power. Projection welding applications may also require platens, specialized fixtures, nut or stud feeders, and process monitoring. WSI application engineers can evaluate your parts and welding requirements to recommend a standard or custom press welder.
Does WSI offer press-type welders for Immediate Delivery?
Yes. Weld Systems Integrators maintains an
IN-STOCK inventory of new and used press-type spot and projection welders at our Warrensville Heights, Ohio facility. Select machines are available for immediate or quick shipment. Inventory changes frequently, so contact WSI at 844-WSI-WELD (974-9353) or 216-475-5629 for current models, specifications, pricing, and availability.
What materials can be welded with a press-type resistance welder?
Press-type resistance welders can weld a variety of conductive metals, including low-carbon steel, stainless steel, galvanized steel, nickel alloys, aluminum, and other weldable materials depending on thickness, electrode design, weld current, force, and power supply. WSI can perform weld testing to determine the proper machine, electrodes, tooling, and weld schedule for a specific material and application.
