?⚙️ Telwin Intelligent Synergy: Welding Has Never Been Simpler and More Precise
The OneTouch LCD Synergy technology implemented in the TELWIN SUPERMIG 450i revolutionizes the approach to setting welding parameters. Forget about tedious paging through tables and the trial-and-error method. Thanks to the intuitive panel with LCD display, all you have to do is select the type of material (carbon steel, stainless steel, aluminum, brazing), the diameter of the wire and the thickness of the workpiece to be welded, and the machine’s microprocessor will automatically select the optimal parameters, such as wire feed speed and arc voltage.
The system offers dozens of predefined synergy curves, developed in Telwin laboratories based on years of research and experience. This guarantees perfect welds from the first use. For the professional, this means huge time savings when rearming the machine for different tasks, repeatable results independent of the operator, and the ability to focus on the welding technique itself. In addition, advanced users still have the possibility to manually adjust the parameters, adapting the arc characteristics to their specific preferences and requirements.
?❄️ ATC Technology: Master Heat Control in Welding Thin Materials
Welding thin sheet metal, especially those sensitive to thermal distortion such as car bodies or thin-walled stainless steel profiles, requires extreme precision and control. TELWIN SUPERMIG 450i with Advanced Thermal Control (ATC) technology is the answer to these challenges. ATC is an innovative system that intelligently modulates the energy of the arc, ensuring a fast ignition and stable glow while reducing the amount of heat introduced into the material being welded.
In practice, this means that the arc is “” cooler,“” which minimizes the risk of burn-through, deformation and stress on the material. This makes it possible to achieve aesthetically pleasing, strong welds even on sheet metal less than 1 mm thick, without the need for complicated techniques or additional cooling. For the professional welder, ATC is a guarantee of quality in delicate work, a reduction in material waste and a reduction in the time needed for post-processing, as welds are cleaner and less prone to distortion.
?? Double the Power, Double the Flexibility: 230V/400V Power Supply for Full Readiness
The TELWIN SUPERMIG 450i PACK stands out in the market thanks to its unique ability to operate on both three-phase 400V and single-phase 230V power. This versatility makes it ideal for workshops with diverse power infrastructures and for companies performing field work where access to the three-phase grid may be limited. When powered by 400V, the welder unleashes its full power potential of up to 450A, allowing it to weld thick steel structures and tackle the most demanding industrial tasks.
Switching to 230V (single-phase) power allows the unit to operate at up to about 300A (estimated value), which is still impressive enough for most production and repair tasks. This flexibility eliminates downtime due to lack of a suitable power source and increases the mobility of the device. For the professional, this means independence, application versatility and the confidence that the welder can meet any challenge, regardless of location or available power infrastructure.
