III. Genuine Parts Procurement & Technical Support
The high-frequency usage characteristics of the AW18 water-cooled TIG welding torch determine that collets, nozzles, tungsten electrodes, and cooling water hoses are core consumables prone to wear. Regularly replacing them with genuine original consumables can significantly reduce the risk of water and gas leaks and improve TIG welding quality. We guarantee to provide 100% genuine original parts and keep ample stock to ensure your operations run smoothly.
