TELWIN TECHNOLOGY TIG 202 AC/DC is a true expert in aluminum welding. The key to success here is advanced alternating current (AC) control. The device allows precise adjustment of AC balance, which is critical for optimal cleaning effect (removal of oxide layer from aluminum surface) and proper penetration. The ability to adjust the frequency of the AC current (typically in the range of 20-200 Hz) allows the arc to be focused, resulting in a narrower weld and a smaller heat affected zone – ideal for precision work and welding thin sheet metal.

In addition, the user has full control over the AC waveform (on some advanced Telwin models, be sure to check the specifications for that particular one), allowing the user to customize the arc characteristics for specific applications, such as a rectangular wave for faster welding and deeper penetration, or a sine wave for a softer arc. These advanced features, combined with precise control of parameters such as starting current, current rise/fall time, and crater current, enable the creation of welds of the highest quality, aesthetics and strength, even on the most demanding aluminum alloys.

While aluminum welding is one of its main strengths, the TELWIN TECHNOLOGY TIG 202 AC/DC is equally adept at direct current (DC) TIG welding. It is ideal for joining stainless steels, carbon steels, copper, titanium, nickel and their alloys. The stable DC arc and precise parameter control produce clean, smooth and durable welds, minimizing the risk of distortion. The TIG Puls DC function is invaluable for welding thin materials, where heat control is crucial, and for welding in forced positions, making it easier to form a perfect weld pool.

The device also offers a full-fledged shielded electrode welding (MMA) mode. This makes it a truly versatile workshop tool. Features such as Arc Force, Hot Start and Anti-Stick significantly simplify work, making the MMA welding process smoother and more efficient, even for less experienced users. The ability to weld with different types of electrodes (rutile, basic, stainless steel, cast iron) opens up a wide range of applications – from minor repairs to assembly and construction work.

The TELWIN TECHNOLOGY TIG 202 AC/DC is designed for maximum efficiency and comfort for the welder. The digital control panel is clear and intuitive, allowing quick access to all key functions and precise adjustment of welding parameters. The display shows the current settings, while dedicated buttons and dials make navigation easy.

Advanced arc control functions, such as the control of shielding gas discharge time before ignition (Pre-gas) and after arc extinction (Post-gas), are key to protecting the tungsten electrode and the weld from oxidation, which directly affects the quality and durability of the joint. The ability to set the time of the current’s rise (Slope-Up) and fall (Slope-Down) allows for a smooth start and stop of welding, eliminating the risk of craters and cracks. The Bi-Level function allows you to quickly switch between two levels of welding current with the push of a button on the handle, which is extremely useful when welding materials of varying thickness or making tack welds. All this makes even complex welding tasks simpler and more predictable.

TELWIN is a well-established brand in the welding market, known for producing equipment of high quality and reliability. The TECHNOLOGY TIG 202 AC/DC model is no exception. The use of inverter technology not only ensures excellent welding performance and high energy efficiency, but also translates into smaller size and weight of the device. Robust construction and high-quality components guarantee a long service life even under intensive use in workshop or industrial conditions.

The device is equipped with a number of safety features, such as thermostatic protection, protection against too high or too low supply voltage, and overload protection. These systems protect both the welder and the user, ensuring safe and stable operation. In addition, the Voltage Reduction Device (VRD) function in MMA mode lowers the idle voltage to a safe level, minimizing the risk of electric shock when working in humid environments. When you choose TELWIN, you are investing in peace of mind and confidence that your tool will meet any challenge.
