Telwin SUPERIOR TIG 422 WAVE AC/DC: a New Standard in Precision Welding
Here is the TELWIN SUPERIOR TIG 422 WAVE AC/DC AQUA+TROLLEY, a real step forward in welding technology, made for professionals who accept no compromise. This is not an ordinary TIG welder, it is an advanced welding centre that redefines precision, output and range. Forget what your equipment stopped you doing and concentrate on getting every joint right. With the WAVE OS operating system you have full control over every aspect of the arc, which brings results that were previously out of reach, above all on demanding materials such as aluminium or magnesium alloys.
Picture welding the thinnest aluminium sheet with surgical precision, producing clean and very strong welds on stainless steel, or joining heavy steel structures without trouble. The SUPERIOR TIG 422 WAVE AC/DC turns those challenges into everyday, satisfying work. With AC welding and full control over the waveform (square, sine, triangular, mixed) and with advanced pulse modes such as SYN PULSE and EASY PULSE, you reduce thermal distortion, raise the welding speed and get sound fusion with little effort.
This model is the essence of Italian engineering and many years of Telwin experience. The integrated AQUA liquid cooling system keeps the parameters stable even during the most intensive work, protects the torch and keeps you comfortable. The TROLLEY makes this powerful machine mobile, so it is always where you need it, ready to work in normal workshop or production conditions. The advanced MMA functions with Arc Force, Hot Start and Anti-Stick make it a genuinely versatile machine.
When you invest in the TELWIN SUPERIOR TIG 422 WAVE, you invest in the future of your workshop, raising the quality of what you offer and opening the door to the most ambitious projects. This machine will not only make your work easier, it will also become a source of pride in perfectly executed welds. See the difference that technology built for master welders makes.
Advanced Capabilities of the TELWIN SUPERIOR TIG 422 WAVE AC/DC AQUA+TROLLEY
Full Control over the AC Arc with WAVE OS
The WAVE OS (Waveform Advanced Versatile Engine) operating system changes the game in AC TIG welding, above all on aluminium and its alloys. Traditional AC welders give limited control over the waveform. The Telwin SUPERIOR TIG 422 WAVE goes further and lets you choose between standard waveforms (square, sine, triangular, mixed) and, more importantly, gives you precise adjustment of the key AC wave parameters, such as balance, frequency (up to several hundred Hz) and even the shape of the individual half cycles.
That lets you match the arc characteristic exactly to the job: aggressive oxide cleaning for heavily contaminated aluminium, a narrow and focused arc for deep penetration, or a soft and quiet arc for thin material. Being able to shape the waveform lets you optimise penetration, bead width and welding speed and reduce the risk of weld defects. For a professional that means not only welds of the highest, radiographic quality but also better output and lower consumption of consumables such as tungsten electrodes.
Advanced Pulsed Welding: Precision and Appearance
The TELWIN SUPERIOR TIG 422 WAVE takes pulsed welding to a new level. Besides standard TIG pulse with full adjustment of frequency, background current and duty, the machine carries the EASY PULSE and SYN PULSE (Synergic Pulse) modes. EASY PULSE sets the pulse parameters by itself, which makes welding thin material easier and helps less experienced welders produce a clean bead.
SYN PULSE is a technology that synchronises the pulse frequency with the arc characteristic and the welding speed, which gives sound control over the weld pool and over the way the ripple forms. Pulsed welding, above all in these advanced modes, is valuable when working with thin sheet (stainless steel, aluminium), where minimal heat input and distortion control decide the result. You can join parts below 1 mm thick, achieve sound penetration and produce welds of unusual appearance and repeatability. For professionals it means precision, less rework and the ability to carry out the most demanding projects.
Reliability and Output from AQUA Cooling and Solid Construction
Working at high current, above all when AC TIG welding aluminium or during long production runs, generates a great deal of heat that can overheat the welding torch and shorten its life. The TELWIN SUPERIOR TIG 422 WAVE in the AQUA version carries a high performance liquid cooling system as standard. The cooling module is integrated with the machine and the trolley, which makes a compact and effective unit.
The AQUA system provides optimal cooling of the TIG torch, which allows continuous work even at maximum parameters, with no overheating and no loss of comfort. That translates directly into higher productivity and longer life for expensive welding torches. The solid construction of the machine itself and the supplied TROLLEY give you both mobility and protection for the welder in hard workshop conditions. A professional can be sure that the equipment is ready for intensive use and will not fail at the wrong moment, which is the basis of profitability and meeting deadlines.

Key Features and Benefits
- WAVE OS with AC waveform personalisation: this is the heart of the machine and lets you match the shape of the AC welding current (square, sine, triangular, mixed) to the aluminium or magnesium alloy in front of you. You gain full control over oxide cleaning, penetration depth and bead profile. For a professional that means welding even the most difficult aluminium grades with sound quality, less risk of porosity, better control of the weld pool and lower tungsten electrode consumption.
- Advanced pulse modes (EASY PULSE, SYN PULSE): the machine offers advanced pulsed TIG functions, including EASY PULSE, which sets the optimal pulse parameters by itself, and SYN PULSE, which synchronises the pulse with the movement of the welder's hand. That lets you weld very thin material (even below 1 mm) with minimal heat input, which reduces distortion and improves the bead appearance. The benefit is easier welding in positional work, better control of penetration and the ability to produce welds with a fine stacked appearance without special skills.
- AC/DC and MMA welding in one machine: the SUPERIOR TIG 422 WAVE is a genuine all rounder. TIG welding with DC covers stainless steel, mild steel, copper and titanium, and AC covers aluminium, its alloys and magnesium. The machine also offers full MMA welding with stick electrodes (rutile, basic, cellulosic, stainless, aluminium) with adjustable Arc Force, Hot Start and Anti-Stick. A professional gets one reliable tool for many different jobs, which removes the need for several welders and saves both space and money.
- Integrated AQUA liquid cooling: intensive TIG welding, above all at high current or long duty cycles, generates a great deal of heat in the welding torch. The AQUA cooling system removes that heat, protects the torch from overheating and damage and keeps the welder comfortable for longer. That means higher output, longer life for the equipment and the ability to work without breaks even on the most demanding jobs, for example welding heavy aluminium sections.
- Clear interface and program memory: despite the advanced functions, the welder is straightforward to operate thanks to the colour TFT display and the clear WAVE OS menu. Being able to store up to 99 of your own welding programs saves a great deal of time and guarantees repeatable parameters in batch work. For a professional that means faster changeover, no setting errors and steady, high weld quality whoever is operating the machine.
- High power and duty cycle for industrial use: with welding current up to 400 A in TIG and 350 A in MMA and a solid duty cycle (for example 400 A @ 40% for TIG), this welder is ready for the hardest work in industry, steel fabrication, production and repair shops. A professional can count on the machine standing up to intensive use and working reliably and continuously when welding heavy parts and long seams.
- A complete mobile package with a trolley (TROLLEY): the machine is supplied with a dedicated trolley that not only makes it easier to move the welder together with the cooling unit and the gas cylinder around the workshop, but also gives an ergonomic working position and order at the welding station. That matters in a busy production environment and improves both efficiency and safety.
