TIG welding (GTAW)
F5 · Professional
The Telwin Superior TIG 422 Wave AC/DC is positioned in the industrial tier due to its 400V three-phase power supply and high output, capable of delivering up to 350A. This makes it a dedicated tool for heavy metalwork shops, shipyards, and intensive industrial production, where prolonged duty cycles and maximum reliability are required. The ability to weld in both alternating and direct current (AC/DC) allows for processing a wide variety of materials, including aluminum, titanium, and special alloys. Its hardware architecture, combined with a weight of 46 kg and a maximum power draw of over 17 kW, requires adequate electrical infrastructure, confirming its vocation for structured and professional work environments with high workloads.

Software
The operating interface is driven by Telwin's proprietary Wave OS (Welding Advanced Visual Environment). This integrated software transforms the welding machine into an advanced digital tool, allowing the operator to customize the welding arc, save specific programs for repetitive tasks, and monitor parameters in real time. The Wave OS system offers advanced features such as weld tracking, which is highly useful for quality control and industrial process optimization. Additionally, a built-in USB port facilitates the export of processing data for computer analysis and allows for quick firmware updates, ensuring the machine remains up to date with the manufacturer's latest innovations and specialized welding program libraries.
Reviews from those who use this machine every day will be available in the next version of the platform.
