The ST2500FX TIG handle features an advanced Up/Down (U/D) function that allows the welder to have full control over key welding parameters without taking their hands off the job. This technology allows infinite current adjustment directly from the ergonomic handle of the handpiece. This is especially important when welding demanding materials or in changing conditions where frequent adjustments are necessary.

The U/D function in Böhler Welding’s fixtures is optimized for use with the brand’s modern welding sources, especially the URANOS NX series, which use digital communication (e.g. CANBUS) and offer advanced user interfaces (e.g. color LCD displays). This makes integration seamless and response to parameter changes instantaneous, resulting in increased precision, higher weld quality and significant time savings by eliminating the need to approach the machine’s control panel. This is part of Böhler Welding’s “Full Welding Solutions” philosophy, which seeks to maximize operator efficiency.

The liquid-cooling system in the Böhler Welding ST2500FX handle is a key technology for reliability and high performance during TIG welding at high amperage and long duty cycles. Efficient heat dissipation from the torch head and current cable protects the handle from overheating, which has a direct impact on its lifespan and the durability of consumable parts such as ceramic nozzles, collets and tungsten electrodes.

Thanks to liquid cooling, the ST2500FX chuck can operate stably even at currents of 250-300A (DC) at 100% duty cycle. This allows continuous welding of thick materials without cooling interruptions, which is invaluable in industrial applications where maximum productivity matters. The solution is an integral part of Böhler Welding’s comprehensive welding systems, designed to work with advanced TIG processes such as FastPulse or AC welding of aluminum, which generate significant amounts of heat.

The TIG ST2500FX handle from Böhler Welding features an ergonomic design and a flexible FX (Flex) head, the result of attention to the highest ‘Made in Europe’ quality standards. The well-thought-out shape of the handle provides a secure grip and reduces operator fatigue even during long hours of work. Lightweight and flexible hoses minimize stress on the wrist, increasing comfort and precision of torch guidance.

The flexible head (FX) allows the torch angle to be easily adjusted to the joint to be welded, which is particularly useful when working in hard-to-reach areas or when welding complex geometries. This flexibility, combined with the high quality of the materials used, guarantees long handle life and reliability in demanding industrial conditions. This solution will be appreciated by professionals for whom every detail that affects the quality of the weld and the efficiency of the work counts.
