TELWIN SUPERIOR TIG 422 AC/DC AQUA + TROLLEY: Full Control and Power for Master Welders
Meet the TELWIN SUPERIOR TIG 422 AC/DC AQUA with trolley, a welding machine that redefines the standards of precision, output and range in professional welding. Built for the most demanding specialists, this advanced TIG and MMA inverter is your key to the most complex projects, from precise joining of aluminium and its alloys to reliable welding of stainless steels, titanium, copper, nickel and magnesium.
Forget compromises. With microprocessor control and the ability to weld with alternating current (AC) and direct current (DC), the SUPERIOR TIG 422 gives you control over the welding process that few machines match. The integrated liquid cooling system (AQUA) keeps the torch in the right working condition even during long, intensive jobs, protects it from overheating and extends its life. That translates directly into your productivity and the quality of the welds you produce.
Functions such as advanced pulsed welding (including the EASY PULSE mode for simplified adjustment), full personalisation of the TIG AC arc parameters (balance, frequency) and the THINSPOT function for fast and precise tacking put you a step ahead of the competition. Picture perfectly smooth bead faces on aluminium, minimal thermal distortion on thin material and confidence in every joint, however complex.
Mobility and ergonomics go together with power. The supplied trolley (TROLLEY) makes it easy to move the machine together with the gas cylinder and the accessories around the workshop or the building site, so your welding station is always where you need it. The TELWIN SUPERIOR TIG 422 AC/DC AQUA is not only a welder, it is a partner that helps you get every detail right, raising the quality of your work and opening the door to new, ambitious contracts.
Advanced Capabilities of the TELWIN SUPERIOR TIG 422 AC/DC AQUA + TROLLEY
Aluminium Welding with TIG AC Technology
The TELWIN SUPERIOR TIG 422 AC/DC AQUA takes the welding of aluminium and its alloys to a new level. The key here is advanced control of the alternating current parameters (AC). You have precise AC balance adjustment, which lets you find the right balance between the cleaning action (removing the oxide layer from the aluminium surface) and penetration depth. That is fundamental for clean, strong and good looking welds.
In addition, the adjustable AC frequency (usually in the 20-200 Hz range) lets you shape the welding arc precisely. Higher frequencies give a narrower, more focused arc, right for precise work and thin parts, while lower frequencies give a wider arc that suits greater thicknesses. Welding with a square, sine, triangular or mixed waveform (depending on the specific functions of the model) widens the range further and lets you optimise the process for different aluminium alloys.
Non-Stop Output with the AQUA Cooling System
Intensive TIG welding, above all at high current and long duty cycles, generates a great deal of heat in the welding torch. The AQUA version of the TELWIN SUPERIOR TIG 422 carries a high performance liquid cooling system that takes the excess heat out of the torch. This matters for keeping the work going and for protecting expensive equipment.
The AQUA cooling unit keeps the TIG torch at the right temperature even when welding at 400 A. For a professional that means no forced stops to let the torch cool, which translates directly into higher productivity. Working with a cooled torch is also more comfortable and considerably extends the life of the torches themselves and their consumables (for example ceramic nozzles and collets). It is an investment that pays back quickly through better efficiency and lower running costs.
Full Process Control for the Professional: Functions and Modes
The TELWIN SUPERIOR TIG 422 AC/DC AQUA offers many functions that let you match the welding process to specific requirements. The arc ignition modes TIG HF (non-contact, high frequency) and TIG LIFT (contact) give you flexibility in different working environments and reduce the risk of tungsten contamination in the weld. The choice of torch mode 2-stroke / 4-stroke / Bi-Level lets you optimise comfort and precision, above all on long seams (4-stroke) or in changing conditions (Bi-Level allows switching between two current levels).
Advanced settings such as start and end current adjustment, current slope up and slope down times, and gas flow time before (Pre-Gas) and after welding (Post-Gas) give the welder full control over every stage of the weld. That is what prevents defects such as pores or craters at the end of a run. In addition, a memory for 9 of your own welding programs lets you recall optimised settings quickly for repeat jobs, which speeds up the work and keeps the results consistent.

Key Features and Benefits
- TIG AC/DC and MMA welding in one machine: the machine welds in TIG with alternating current (AC), which suits aluminium and magnesium, and with direct current (DC) for stainless steel, mild steel, copper, titanium and others. It also gives full support for stick electrode welding (MMA) with AC and DC current. For a professional that means one versatile tool for a wide span of tasks, which removes the need to invest in several machines and shortens the preparation time between different jobs.
- Integrated AQUA liquid cooling: the dedicated liquid cooler keeps the TIG torch properly cooled even during long work at high current. That extends the torch life considerably, prevents overheating and holds the welding parameters stable. The benefit is higher productivity through longer working cycles, less risk of downtime and more comfort for the welder.
- Advanced pulsed TIG welding functions (Standard & EASY PULSE): welding with pulsed current in DC and AC mode, with full adjustment of the pulse parameters (frequency, background, duty) or in the simplified EASY PULSE mode. Pulsing gives better control of the weld pool and lower heat input, which is what you need on thin material and stainless steel, and produces welds with a fine ripple. The result is less distortion, better penetration and higher joint quality, even for less experienced operators (thanks to EASY PULSE).
- Precise TIG AC parameter adjustment for aluminium: full control over AC balance (which affects cleaning and penetration) and over AC frequency (which affects arc focus and welding speed). These functions are essential for high quality welds on aluminium and its alloys, minimising the risk of oxide inclusions and giving sound fusion. A professional can match the arc characteristic exactly to the job, the material and the thickness.
- THINSPOT function and remote control: the THINSPOT function allows fast and precise spot welding (tacking) at minimal current, which is very useful when assembling thin sheet. The machine is also prepared to work with various types of remote control (foot pedal, control in the torch handle). For the welder that means more precision and control over the process, faster preparation of parts and the option of adjusting the parameters while welding without taking your hands off the work.
- Mobility and completeness with the trolley (TROLLEY): the set includes a dedicated transport trolley that not only makes it easier to move the welder together with the cooling unit, but also carries the shielding gas cylinder and the necessary accessories. This ergonomic solution improves the organisation of the workstation and the mobility of the whole welding system within the workshop or production hall.
