Get to Know the Advanced Options of the TELWIN SUPERIOR TIG 422 AC/DC 230V/400V
Mastery of AC Welding for Aluminium and Light Alloys
Welding aluminium requires not only power but above all precise control over the alternating current (AC). The TELWIN SUPERIOR TIG 422 AC/DC offers advanced options here. The key role is played by AC balance adjustment, which lets you balance the cleaning phase (removing oxides from the aluminium surface) and the penetration phase (deep fusion) perfectly. This gives you welds that are free of contamination and have excellent structural integrity.
Another important parameter is AC frequency adjustment. Higher frequencies (up to 200 Hz or more, depending on the model specification) give a more concentrated and stable arc, which is invaluable when welding thin aluminium sheet, precise corners or fillet welds. Lower frequencies may be preferred for thicker materials, giving a wider arc and a larger weld pool. The SUPERIOR TIG 422 gives you full control, so you can match the arc characteristics to the specific task, material and thickness and obtain the highest quality of joint.
Intelligent TIG Pulse (EASY PULSE, SYN PULSE) for Perfect Welds
Pulsed TIG welding is a technique that transforms work with thin materials, stainless steels and other heat sensitive alloys. The TELWIN SUPERIOR TIG 422 is equipped with advanced pulse modes, including EASY PULSE and SYN PULSE. EASY PULSE mode automatically selects the best pulse parameters (frequency, base current, pulse cycle) on the basis of the selected peak current, which simplifies the setup considerably and is ideal for less experienced welders or when the speed of setting matters.
For more advanced users, full manual control of the pulse parameters in the standard pulse mode and the innovative PULSE SYN (Synchronized Pulse) open new possibilities. PULSE SYN often offers additional benefits, such as even better control over the weld pool, reduced distortion and the option of obtaining very attractive welds with the characteristic "fish scale" pattern. Whichever mode you choose, pulsed welding with the SUPERIOR TIG 422 means less heat input, better control over penetration, especially in constrained positions, and excellent results on materials even below 1 mm thick.
230V/400V Supply Flexibility and Industrial Reliability
One of the key advantages of the TELWIN SUPERIOR TIG 422 is its ability to work both with a single phase 230V supply and with a three phase 400V supply. The machine automatically recognises the mains voltage and adjusts its working parameters, giving the best output in typical workshop conditions. This function makes it an exceptionally versatile tool, ideal for stationary work in a well equipped industrial workshop (400V) as well as for mobile tasks, service work on site or in smaller workshops where only a 230V supply is available.
Whatever the power source, the SUPERIOR TIG 422 guarantees industrial reliability. Built from high quality components, fitted with an efficient cooling system and advanced protections (thermal, overload, overvoltage and undervoltage), it is ready for intensive work in difficult conditions. The solid housing protects the internal mechanisms against mechanical damage and dust (IP23 protection rating). This is an investment that gives you peace of mind and the certainty that your tool will meet every challenge.
The Innovative THINSPOT Function, Precision in TIG Spot Welding
The TELWIN SUPERIOR TIG 422 introduces the THINSPOT function, which transforms the process of tacking and spot welding with the TIG method. This intelligent technology lets you make very fast and precise weld points with minimal heat input into the material. This is especially useful when working with thin sheet, where traditional tacking methods can lead to burn through or excessive distortion.
Thanks to the THINSPOT function, you can control the duration of the current pulse exactly, which gives a repeatable size and quality of the tack point. The process is exceptionally fast, which raises productivity considerably, especially when assembling complex structures that need many positioning points. Minimising the heat affected zone is another key advantage, which reduces internal stresses and material distortion, making the further stages of the main welding easier and giving higher quality of the final product. This function is invaluable in sectors such as the production of thin walled tanks, body parts or precise stainless steel structures.
