TELWIN TECHNOLOGY TIG 202 AC/DC: professional welding of aluminium and steel with high precision.
The TELWIN TECHNOLOGY TIG 202 AC/DC is a microprocessor controlled inverter welder that changes the way you work with the TIG and MMA processes. It was built for demanding professionals and ambitious hobby users, and it answers the need for versatility, precision and reliability in daily work. Whether you weld thin aluminium, difficult stainless steel or plain carbon steel, the TECHNOLOGY TIG 202 AC/DC gives you the tools to reach a clean result every time.
Think of welding without compromises. Advanced AC current control lets you join aluminium alloys with full command of the process, with good cleaning action and deep fusion. Switch to DC and you weld stainless steel, carbon steel, copper, nickel, titanium and their alloys with fine accuracy. This is more than a welder, it is a partner in complex projects, from precision repairs through short run production to artistic structures.
The TELWIN TECHNOLOGY TIG 202 AC/DC is not only power and versatility. It is also smart technology packed into a compact and rugged housing. Pulse welding (PULSE and EASY PULSE) gives full control over the weld pool, keeps thermal distortion low and produces clean beads even on thin material. Arc ignition by high frequency (HF) or by LIFT, together with the MMA support functions (Arc Force, Hot Start, Anti-Stick), makes the work intuitive, efficient and genuinely satisfying.
By choosing the TELWIN TECHNOLOGY TIG 202 AC/DC you invest in quality that pays back in practice: shorter working time, lower material cost thanks to fewer corrections and a higher standard of the service you offer. Join the specialists who trust the TELWIN brand and see the difference that world class welding technology makes. This model with the full accessory kit (+ACC.) is ready for work straight out of the box and gives you everything you need to start the next welding job.
A closer look at the TELWIN TECHNOLOGY TIG 202 AC/DC 230V+ACC.
Accurate aluminium welding with AC TIG technology
The TELWIN TECHNOLOGY TIG 202 AC/DC is a real specialist in aluminium welding. The key here is advanced alternating current control. The machine allows precise AC balance adjustment, which is critical for the right cleaning effect (removal of the oxide layer from the aluminium surface) and for correct penetration. Setting the AC frequency (usually in the 20-200 Hz range) focuses the arc, which gives a narrower bead and a smaller heat affected zone, ideal for fine work and for welding thin sheet.
In addition, the user has full control over the AC wave shape (on some advanced Telwin models, please check the specification of this particular unit), so the arc character can be matched to the application, for example a square wave for faster welding and deeper penetration, or a sine wave for a softer arc. These functions, together with precise control of parameters such as start current, slope up and slope down time or crater current, allow welds of the highest quality, appearance and strength even on the most demanding aluminium alloys.
Versatile TIG DC and MMA for professionals
Aluminium welding is one of the main strengths, but the TELWIN TECHNOLOGY TIG 202 AC/DC handles TIG welding on direct current (DC) just as well. This is the right choice for joining stainless steels, carbon steels, copper, titanium, nickel and their alloys. A stable DC arc and precise parameter control give clean, smooth and strong welds with a low risk of distortion. The TIG Pulse DC function is valuable on thin material, where heat control decides the result, and in out of position welding, where it helps to form the weld pool.
The machine also offers a full stick electrode (MMA) welding mode, which turns it into a truly universal workshop tool. Functions such as Arc Force, Hot Start and Anti-Stick make the work much easier and the MMA process smoother and more efficient, also for less experienced users. Welding with different types of electrode (rutile, basic, stainless steel, cast iron) opens a broad field of use, from small repairs to assembly and structural work.
Intuitive operation and advanced arc control
The TELWIN TECHNOLOGY TIG 202 AC/DC was designed for maximum efficiency and welder comfort. The digital control panel is clear and intuitive and gives quick access to every key function and precise setting of the welding parameters. The display shows the current settings, and the dedicated buttons and knobs make navigation easy.
Advanced arc control functions, such as adjustment of the shielding gas flow before ignition (pre-gas) and after the arc goes out (post-gas), protect the tungsten electrode and the weld against oxidation, which directly affects the quality and durability of the joint. Setting the slope up and slope down time allows a gentle start and end of welding and removes the risk of craters and cracks. The Bi-Level function switches quickly between two welding current levels using the torch button, which is very useful on material of changing thickness or when making tack welds. Even complicated welding tasks become simpler and more predictable.
Reliability and safety of the TELWIN brand
TELWIN is an established brand on the welding market, known for equipment of high quality and reliability. The TECHNOLOGY TIG 202 AC/DC model is no exception. Inverter technology not only gives good welding parameters and high energy efficiency, it also keeps the size and the weight of the machine down. Solid construction and quality components mean a long service life even under intensive use in workshop or industrial conditions.
The unit carries a set of protections, such as thermostatic protection, protection against supply voltage that is too high or too low, and overload protection. These systems protect both the welder and the operator and keep the work safe and stable. The VRD (Voltage Reduction Device) function in MMA mode lowers the open circuit voltage to a safe level and reduces the risk of electric shock when working in a damp environment. With TELWIN you choose peace of mind and a tool that will cope with the job.

Key features and benefits
- Versatile TIG AC/DC and MMA welding: the machine covers TIG welding both on alternating current (AC) for aluminium and its alloys (including magnesium) and on direct current (DC) for stainless steel, carbon steels, copper, nickel, titanium and their alloys. The stick electrode (MMA) function makes it a universal tool. For a professional this means one machine for many kinds of project, from precise beads on thin aluminium sheet to structural stick welding, which saves space and the cost of buying several machines.
- Advanced TIG AC/DC parameter control with pulse: microprocessor control allows precise setting of the key TIG parameters, such as AC balance (control of the cleaning effect and of penetration when welding aluminium), AC frequency (arc focus), gas flow before and after welding, start and end current, and slope up and slope down time. Pulse welding (PULSE and EASY PULSE) gives close control of the heat input. The result is less distortion, the ability to weld very thin material, neat welds of repeatable quality and better control of the weld pool in out of position work.
- Dynamic HF/LIFT arc ignition and a stable process: the welder has two TIG ignition modes: non contact high frequency (HF) for a clean start without contamination of the electrode and the material, and contact LIFT for work in environments sensitive to electromagnetic interference. The electronics keep the arc stable and concentrated. For the welder this means an easier start, less risk of tungsten inclusions and welds of higher quality, also in difficult conditions.
- Smart support functions for MMA welding: in MMA mode the user can rely on functions such as Arc Force (dynamic short circuit current control that helps in difficult positions and keeps the arc from dying), Hot Start (a short current boost at the start that helps to strike the electrode) and Anti-Stick (prevents the electrode from sticking to the material). The machine also has a VRD (Voltage Reduction Device) function for greater safety. The effect is smoother MMA welding, fewer problems with a sticking electrode and easier correct fusion, which decides the durability and safety of the structure.
- Compact build, ready for work: despite the advanced functions and high power, the TELWIN TECHNOLOGY TIG 202 AC/DC stays fairly small and light, which helps with transport and site work. The +ACC. version comes with a set of TIG welding accessories (torch, consumables) and often with MMA accessories as well. The welder gets a complete solution ready for use, which saves the time and effort of putting the equipment together.
