TECNA 3020Q-3169 Pneumatic Suspended Spot Welding Guns for Resistance Welding

TECNA suspended pneumatic spot welding machines are engineered for companies requiring reliable, high-performance solutions for industrial resistance spot welding applications. Designed for continuous production environments, these machines combine consistent weld quality, high electrode force, ergonomic handling and long service life, making them suitable for demanding sheet metal fabrication, automotive components and manufacturing operations.

The TECNA 3020Q-3169 range represents a complete family of pneumatic hanging spot welders developed to meet different industrial requirements. Available from 32 kVA to 75 kVA, the series offers multiple configurations with integrated or separate electronic controls, different arm geometries and adjustable welding parameters to achieve the optimum solution for each application.

The range includes the C and CG versions (3020Q-3041Q), designed for compact and versatile applications, the L and LL versions (3120-3127) for extended working requirements, and the LG and LLG models (3154-3169) for applications requiring greater reach and flexibility. Each configuration can be adapted according to component dimensions, material thickness, welding accessibility and production volume.

For customers searching for a specific TECNA machine model, the complete series includes 3020Q, 3021Q, 3024Q, 3025Q, 3032Q, 3033Q, 3040Q, 3041Q, 3120, 3121, 3122, 3123, 3124, 3125, 3126, 3127, 3154, 3155, 3156, 3157, 3160, 3161, 3162, 3163, 3166, 3167, 3168 and 3169. This wide selection allows engineers and production managers to identify the most suitable TECNA spot welding machine according to required power, electrode force, arm length and working conditions.

Choosing the correct suspended spot welding machine depends on several factors, including the material to be welded, sheet thickness, component shape, accessibility of welding points, production cycle time and required automation level. ATS supports customers in selecting the most suitable TECNA configuration, providing technical consultancy, application evaluation, accessories supply, original spare parts and specialised after-sales assistance.

Designed for demanding industrial environments, TECNA machines provide excellent reliability during intensive production cycles. The compact construction reduces machine footprint while maintaining high welding performance. The protected structure improves durability and safety, while transformers manufactured according to ISO 5826 standards guarantee stable and repeatable welding results.

A major advantage of the TECNA range is the gyroscopic suspension system. Combined with a suitable balancer, it allows smooth positioning in all directions, improving operator control when welding large components or complex assemblies. The rotation locking system increases stability during operation, ensuring accurate positioning and repeatable weld quality.

The mechanical design focuses on productivity and flexibility. Adjustable working stroke helps optimise cycle times, while the large instantaneous opening improves access to difficult welding points. High opening capacity allows efficient welding of reinforced panels, boxed sections, structural components and complex fabricated parts.

The pneumatic drive system provides high electrode pressure, producing uniform and reliable weld spots even during continuous operation. The chrome-plated cylinder and piston rod are designed for heavy industrial use, while the oil-free pneumatic circuit reduces maintenance requirements and improves workplace cleanliness.

The water-cooled copper secondary circuit maintains stable operating conditions during long production cycles. Cooling of electrodes, electrode holders and critical components reduces thermal stress and helps preserve consistent weld performance over time. Dedicated cooling valves simplify maintenance operations and electrode replacement.

Electronic control options include integrated TE470 and TE480. These systems allow management of multiple welding programmes, parameter adjustment, current monitoring and advanced functions including pre-welding, post-welding, pulsing, incremental adjustment, constant current control and double stroke operation.

The ability to quickly select different welding programmes directly from the handle improves production flexibility and reduces changeover times between different components or welding applications.

Safety and ergonomics are key elements of the TECNA design. Machines are equipped with thermal-magnetic protection, 30 mA residual current safety protection and systems designed to prevent accidental operation. Additional protection circuit monitoring is available on request, while the ergonomic handle provides intuitive control during daily production activities.

The extensive range of available options allows each machine to be configured precisely for the application. Different arm lengths, throat depths, electrode forces and power ratings are available, with selected models capable of welding mild steel sheets up to 4.5 + 4.5 mm. Long-reach versions are available for components where welding points are located in difficult-to-access areas.

A complete range of accessories is available, including cooling water flow switches, additional handles, two-program supports, proportional pressure control valves, customised arms, dedicated electrodes, power cables and insulated rotating hook balancers designed to improve handling, ergonomics and operator efficiency.

TECNA resistance spot welding equipment is used across multiple industrial sectors including metal fabrication, automotive manufacturing, appliance production, metal furniture, industrial equipment and welded wire component manufacturing. The combination of reliability, flexibility and precise welding control makes these machines suitable for both manual workstations and high-productivity manufacturing environments.

ATS Lamberti provides complete support throughout the entire machine lifecycle, from technical selection and configuration through installation, commissioning, spare parts supply and specialised service. By combining TECNA technology with application expertise, ATS helps customers achieve reliable welding processes, improved productivity and long-term operational efficiency.
