B\u00f6hler Welding ST 4000 FX U\/D TIG welding gun – 4m – Liquid-cooled – 81.32.271<\/h2>\n
\n

The B\u00f6hler Welding ST 4000 FX U\/D TIG professional liquid-cooled 4-meter long welding handle is designed for the most demanding industrial applications. Featuring intuitive Up\/Down (U\/D) welding parameter control directly on the handle, it gives the welder maximum control over the process without interrupting the work. Its robust design and powerful liquid cooling guarantee reliability and high performance even when welding with high currents, making it the ideal tool for professionals who expect the highest quality and precision from Voestalpine B\u00f6hler Welding. <\/p>\n

The ST 4000 FX U\/D TIG chuck is a key component of B\u00f6hler Welding’s ‘Full Welding Solutions’, designed to work optimally with the brand’s advanced TIG welding sources, enabling full use of their innovative features. Dedicated to professionals in industries such as heavy industry, power generation, shipyards and automotive, where every detail and uncompromising weld quality counts. <\/p>\n<\/div>\n<\/div>\n

\n
\n\u2b06\ufe0f\u2b07\ufe0f Precision Up\/Down Parameter Control (U\/D)<\/summary>\n
\n

The integrated Up\/Down (U\/D) function on the B\u00f6hler Welding ST 4000 FX TIG handle is the key to maximum control over the welding process without taking your hands off the job<\/strong>. Buttons ergonomically located on the handle allow you to instantly adjust the welding current or other selected parameters<\/strong> (depending on the capabilities of the B\u00f6hler Welding power source). <\/p>\n

For the professional, this means a significant increase in efficiency and precision<\/strong>, especially when welding workpieces with variable thicknesses, in forced positions or when using the advanced pulse functions of B\u00f6hler Welding’s TIG sources. The ability to fine-tune parameters “on the fly” minimizes the risk of errors, reduces the number of corrections and produces welds of excellent quality and repeatability<\/strong>. This technology is invaluable for jobs requiring focus and the highest quality, such as welding stainless steels, aluminum or special alloys. <\/p>\n<\/div>\n<\/details>\n

\n? Flexible Torch Body FX (Flexible Torch Body)<\/summary>\n
\n

The FX design, or Flexible Torch Body, in the B\u00f6hler Welding ST 4000 FX U\/D TIG torch<\/strong> holder is an innovative solution that significantly improves comfort and ergonomics. Thanks to the ability to easily adjust the angle of the torch head<\/strong>, the welder gains unparalleled freedom of maneuverability and optimal access to welds in hard-to-reach places<\/strong> and with complex joint geometries. <\/p>\n

The benefits for the professional are tangible: reduced operator fatigue<\/strong> during prolonged work, the ability to maintain a more stable arc<\/strong> due to better torch alignment, and improved weld quality and aesthetics<\/strong> through more precise electrode guidance. The flexibility of the FX body, combined with the quality of B\u00f6hler Welding’s workmanship, makes this holder a tool that adapts to the welder and<\/strong> the task<\/strong>, not the other way around, which is crucial in demanding industries. <\/p>\n<\/div>\n<\/details>\n<\/div>\n
