TECNA portable spot welding guns deliver reliable resistance welding performance for applications where fixed welding machines cannot provide the access or flexibility required. Available in scissor-type, C-type, and robot configurations, with AC and MFDC power options.
C-type guns are built around a fixed C-shaped frame: the lower electrode is rigidly mounted at the base of the C, while a pneumatic cylinder drives the upper electrode down from the top. Because electrode alignment is set by the frame’s mechanical structure — not the operator’s hand positioning — C-type guns excel in applications where weld placement repeatability is tightly specified. The open frame also gives the operator a clear, unobstructed view of both electrodes and the weld area. Available in AC and MFDC.
Robot weld guns mount directly to the tool flange of an industrial robot arm, putting spot welding under full robotic control. Instead of an operator guiding the gun, a six-axis robot positions the electrodes at each programmed weld point — repeatable to within fractions of a millimeter — and executes weld after weld at a steady pace through an entire production run. TECNA robot guns are purpose-built for this kind of integration, delivering the electrode performance of the TECNA platform in a robot-ready package. They’re a natural fit for automotive, appliance, and high-volume stamped metal assembly lines. Available in AC and MFDC.
Scissor-type guns use two electrode arms mounted on a central pivot. The actuator drives the lower arm in a scissor motion, closing the electrodes onto the workpiece. This design excels at reaching difficult weld locations — deep flanges, enclosed sections, and weld points where obstructions block a straight-on approach — and the arms open wide enough for clearance when moving into and out of challenging locations to make the weld. Available in AC and MFDC.
A welding station combines a TECNA portable gun with everything needed to put it to work — suspension, balancing, cooling, and mobility — in a single integrated system. Rather than sourcing and assembling these elements separately, the station arrives as one engineered package: a wheeled console, a suspension arm that carries the gun’s weight and cable load, a balancer retractor for smooth, effortless positioning, and a self-contained water-cooling circuit. Roll it to the work, connect shop power and air, and it’s ready for production — no integration engineering required. TECNA welding stations feature SMART adaptive control that adjusts welding parameters weld by weld, and are ready for robot and cobot integration when an operation is ready to automate.
Portable Spot Welding Solutions
TECNA portable spot welding guns provide the performance of a production resistance welder in a flexible, mobile design. With the welding transformer and control integrated into the gun body, these systems allow operators or robots to reach weld locations that may be difficult or impossible to access with a fixed machine.
Portable guns are commonly used in automotive body and chassis assembly, commercial vehicle fabrication, rail and transportation manufacturing, appliance production, agricultural equipment, and large weldments.
Choose the Right Welding Gun
Scissor-Type Weld Guns
Scissor-type guns use two electrode arms mounted on a central pivot, making them ideal for reaching difficult weld locations such as deep flanges, enclosed sections, and areas where obstructions limit access. Available in AC and MFDC configurations.
C-Type Weld Guns
C-type guns feature a fixed C-shaped frame that provides consistent electrode alignment and excellent weld placement repeatability. The open frame provides clear visibility of the weld area and is available in both AC and MFDC configurations.
Robot Weld Guns
Robot weld guns mount directly to an industrial robot arm, providing automated and highly repeatable spot welding. They are well suited for high-volume production environments such as automotive, appliance, and stamped metal manufacturing. Available in AC and MFDC configurations.
Designed for Production
TECNA portable welding guns combine precise electrode force, efficient water cooling, balanced construction, and reliable welding performance. When paired with a properly sized balancer or welding station, the system provides smooth positioning and reduced operator fatigue while maintaining the performance required for demanding production environments.
