The Multi Voltage (MV) system on the TELWIN ADVANCE 227XT is a true revolution for mobile professionals. The unit automatically recognizes the supply voltage from 100V to 240V, eliminating the need for manual configuration or additional transformers. Whether you’re working in the country with a different standard voltage or on a construction site with an unstable power supply, the welder will deliver full power.

Power Factor Correction (PFC) technology is another step forward. Active PFC ensures that the device draws current from the grid in a sinusoidal manner, close to an ideal resistive load. This translates into a power factor close to unity (0.9), which means less energy loss, reduced grid load and less harmonic distortion. In practice, this means the ability to run longer power cables without significant power drops, lower energy bills and a more stable welding arc, even with less efficient power sources like generators. It’s smart energy management that translates into your productivity and savings.

In the welding industry, safety is an absolute priority. The TELWIN ADVANCE 227XT with Voltage Reduction Device (VRD) is designed for maximum operator protection, especially when working in high-risk environments such as wet, tight or conductive spaces (e.g., inside tanks, on ships, in mines).

When welding is not active (idle state), the VRD system automatically reduces the voltage at the electrode to below 25V. This is a value that is considered safe, minimizing the risk of accidental electrocution when contact is made with the electrode and the welded part. The VRD function can be turned on or off by the user depending on the requirements and regulations of the workplace. For a professional who cares about his and his team’s safety, the presence of the VRD system is an invaluable advantage, allowing them to work more confidently and in accordance with the latest safety standards.

The TELWIN ADVANCE 227XT is a true specialist in MMA welding, offering a suite of intelligent features that make work easier and more efficient. Hot Start ensures optimal arc ignition by delivering increased current at the very beginning of the process. This is especially useful with cold materials or difficult to ignite electrodes (such as alkaline).

Arc Force (arc dynamics) function is the key to stable welding. This system automatically adjusts the current depending on the arc length. When the arc shortens (e.g., when the electrode is brought closer to the material), the current is temporarily increased, preventing the arc from “dimming” and sticking the electrode. This allows welding with a short arc, which is desirable for deep fusion and high weld quality. The Anti-Stick function, on the other hand, immediately reduces the welding current when the electrode sticks to the material, allowing the electrode to be easily detached without damage to the electrode or the material. These synergistic systems translate into working comfort, fewer spatters, better control of the weld pool and excellent results even in difficult conditions and when welding in forced positions.

The TELWIN ADVANCE 227XT extends its capabilities beyond the MMA method by offering high-quality TIG Lift DC welding. This method, with arc ignition by rubbing the tungsten electrode against the material (Lift Arc), is ideal for jobs requiring high precision, weld aesthetics and minimal heat impact on the welded part. It is ideal for welding thin sheet metal, pipes and parts made of stainless steel, low-alloy carbon steel, copper or titanium.

The ADVANCE 227XT’s TIG Lift process provides a smooth start to welding without the risk of tungsten contamination of the weld, a common problem with simpler systems. Stable welding current and the ability to adjust it precisely allow full control over the weld pool, which is crucial when creating welds with high quality and aesthetic requirements. For professionals performing installation, repair, artistic or food and chemical industry work, the TIG Lift welding capability makes the ADVANCE 227XT an even more versatile and valuable tool.
