The AC/DC version allows welding aluminum and magnesium in AC mode, thanks to a frequency adjustable over a wide range of 25-300 Hz, making it easier to precisely shape the weld pool and control heat. Professionals appreciate this for greater flexibility when joining a variety of alloys, while being able to count on 200 A at 100% duty cycle. If someone doesn’t plan to weld aluminum, the DC model (13 kg) is ideal for steel and titanium, but buying the AC/DC variant guarantees protection for future projects. Less experienced operators will find it a versatile tool that grows with them, from basic repairs to advanced production tasks.

The CenTIG 200 offers an award-winning interface that was recognized as an exemplary example of functional design in the iF Design Award 2025. All relevant parameters (current, AC frequency, balance, pulse, etc.) can be set instantly, thanks to simplified navigation and a highly readable screen. Operators working in high-speed production cycles will also appreciate the ability to save and recall favorite programs, which shortens interruptions between jobs. Less skilled welders will find such a design reassuring, as they won’t get lost in the maze of functions and operation will be reduced to a few logically arranged options. As a result, everyone can focus on weld quality without wasting time on unnecessary settings.

The CenTIG 200 retains 200 A in continuous operation at 40°C, virtually eliminating the risk of downtime due to source overheating. In production applications or longer stitches, this is a huge advantage, as the welder does not have to schedule intermittent sessions or reduce parameters to protect the machine. Experts note that these efficiencies reduce total project time and improve workflow, while beginners gain the comfort of learning without unnecessary interruptions and machine shutdowns of their own. Every minute of welding becomes more efficient because the device always maintains stable arc parameters.

The DC model weighs only 13 kg, while the AC/DC model weighs 13.6 kg, making the CenTIG 200 the lightest TIG source in its power class. Such a feature is appreciated in situations where the welder must change positions frequently, such as in field repairs, assembly lines or mobile services. Combined with the ergonomic handle and optional strap, transporting the unit does not strain the back and allows the user to get to the welding site quickly. For less experienced operators, the lightweight design also means easier setup and organization in the workshop, where every inch of free space counts. The result is great mobility while retaining full advanced TIG features.

TIG welding requires precision in arc ignition and handle guidance, and in 4T mode, the operator does not have to hold down the button constantly. Welding start and stop are controlled by two short button presses, reducing fatigue and increasing handle stability for longer stitches. In addition, the implemented high-frequency (HF) ignition allows for smooth, non-contact ignition of the tungsten electrode without the risk of fouling. As a result, professionals achieve precise welds with high purity, and less experienced people do not struggle with uncontrolled touching of the material with the electrode. The whole thing translates into higher comfort and better final weld quality.

The pulse function allows periodic changes in welding current to reduce heat input and maintain a stable weld pool in thinner materials. Professionals use the pulse to reduce distortion in stainless steel and minimize edge scorching, which shortens the finishing step. The CenTIG 200 also provides fully adjustable pre and post gas, as well as current rise and fall times, making it easy to tailor parameters to the specifics of the project. Less experienced operators achieve aesthetically pleasing welds faster because the pulse dictates the melting rhythm, and optimal gas flow control (such as IGC) eliminates the risk of insufficient arc shielding. The result is high repeatability and fewer errors in the welding process.

The CenTIG 200 is equipped with two innovative thin part tacking techniques. TIG-A-Tack is used to create extremely small and almost invisible attachment points in the finished weld, which will be appreciated by industries with high aesthetic requirements (e.g., the stainless steel or design industries). TIG-REP-Tack, on the other hand, generates a series of tiny tack points in ultra-thin metal sheets (from 0.5 mm), fusing them into a single continuous seam, which is sometimes indispensable for precision applications without the risk of overheating. Specialists use these functions for delicate structures and advanced projects requiring aesthetics, while those with less experience gain fastening stability without the need for conventional “scrubbing” or concern about electrode sticking. Such semi-automatic processes simplify the tacking process and significantly save time in preparing components before full welding.

IGC takes care of automatic, synergistic regulation of gas flow, which translates into optimal arc shielding and at the same time a reduction in gas consumption costs. In industrial settings, where many welds per day are realized, such savings become important and protect against possible defects caused by insufficient gas. In addition, the CenTIG 200 allows you to save your favorite welding settings and programs, which is quite a convenience in teams where one machine may be shared by multiple welders. Advanced specialists program parameters for different alloys and sheet thicknesses in advance, while less skilled operators can use them without the risk of mistakes. This memory function makes the machine as good for one-off repairs as it is for series production.
