The synergy technology in the ELECTROMIG 400 is a real breakthrough in ease of use and welding quality. With built-in synergy curves optimized by Telwin engineers, the welder automatically adjusts the wire feed speed to the set welding current and the selected material, wire diameter and shielding gas. All you have to do is select the appropriate program and the machine takes care of the rest, ensuring ideal arc performance.

For the professional, this not only means a huge saving of time that would normally be spent manually setting and testing parameters, but also a guarantee of repeatability and high weld quality, even for less standard tasks. The synergy system minimizes the risk of errors, such as sticking wire, excessive chipping or improper fusion. It is the ideal solution for both experienced welders who value speed and precision, and for companies that want to ensure a uniform, high standard of work for their employees.

One of the most distinguishing features of the ELECTROMIG 400 SYNERGIC is its ability to work with both single-phase 230V and three-phase 400V. The device automatically recognizes the type of connected power supply and adjusts its operating parameters. This versatility opens up entirely new possibilities for professionals.

Imagine the situation: you are working on a large construction project on the shop floor, using the full power of a welding machine on 400V power. The next day you need to make an urgent repair at a customer’s site, where only a standard 230V outlet is available. With ELECTROMIG 400 this is not a problem! You have the confidence that your tool is up to the task, offering a significant portion of its power even at a lower supply voltage. This is not only a convenience, but also a real savings – you do not need to invest in a second, smaller welder for mobile work. This is one device that adapts to your needs, not the other way around.

Welding thin sheet metal, especially those susceptible to thermal distortion, such as in the automotive industry or in the production of stainless steel parts, requires extreme precision and control over the arc line energy. The TELWIN ELECTROMIG 400 SYNERGIC is equipped with innovative ATC (Advanced Thermal Control) technology, which was developed specifically for such applications.

The ATC system intelligently modulates the energy delivered to the weld pool, ensuring fast and stable arc ignition and precise arc guidance with minimal heat input. This results in significantly reduced material distortion, less risk of burn-through and aesthetically pleasing, smooth welds. For the professional, this means higher quality of the final product, a reduction in the time required for post-weld processing (e.g. straightening, grinding), and the ability to work with materials as thin as less than 1 mm with full control. ATC technology is a guarantee of excellent results where every detail counts.

TELWIN ELECTROMIG 400 SYNERGIC is a device designed for heavy, daily work in demanding industrial conditions. Its robust metal housing protects the internal components from mechanical damage and dust (protection class IP23). At the heart of the wire feeding system is a professional 4-roller mechanism that guarantees smooth and stable feeding of the welding wire, regardless of its type or holder length. This is crucial for maintaining arc stability and weld quality, especially when welding for long periods of time.

A high-efficiency transformer and advanced cooling system ensure high duty cycle (e.g., 400A at 30% for 400V), allowing long welding sessions without the risk of overheating. All components have been selected for maximum durability and reliability. For the user, this means minimized service downtime, long machine life and confidence that the welder will stand up to even the most intensive production tasks. It’s an investment that pays off over years of trouble-free operation.
