Easy replacement parts The limit sleeve, main shaft, insulating sleeve, and gas handle are designed for individual disassembly and replacement. This reduces maintenance costs and enhances user convenience by allowing you to only the worn components instead of the whole unit. Even treatment distribution With 12 water outlets, this machine delivers uniform cooling across the brush head bristles. This helps prevent hotspots and overheating, reducing the risk of malfunctions and improving overall performance. Extended service life The design extends the average service life of both the treatment unit and the cleaning gas, providing reliable, longlasting performance for your welding tasks. 3meter long tube The 3meter tube length provides ample reach for various welding applications, allowing you to work comfortably on larger projects and in tight or distant spaces. Typical use scenarios Longreach welding on automotive frames, machinery housings, or structural components where consistent cooling and dependable performance are important. Maintenance and tasks that require easy replacement of components (limit sleeve, main shaft, insulating sleeve, gas handle) to minimize downtime. Fabrication of large panels or pipe work in workshops where the 3meter reach and uniform bristle cooling support efficient, quality results.
