Discover the Advanced Capabilities of the TELWIN ELECTROMIG 400 SYNERGIC 230V/400V
Intelligent TELWIN Synergy: Welding Simpler Than Ever
The synergic technology in the ELECTROMIG 400 model is a real step forward in ease of use and welding quality. Thanks to the built in synergic curves optimised by Telwin engineers, the welder adjusts the wire feed speed automatically to the set welding current and to the chosen material, wire diameter and shielding gas. All you have to do is select the right program and the machine takes care of the rest and gives ideal arc parameters.
For a professional this means not only a large saving of the time that would normally go into setting and testing parameters by hand, but also a guarantee of repeatability and high weld quality, even on less standard tasks. The synergic system reduces the risk of faults such as the wire sticking, excessive spatter or poor penetration. It is an ideal solution both for experienced welders who value speed and precision and for companies that want to give their staff a uniform, high standard of work.
230V/400V Supply Flexibility: Power Where You Need It
One of the most distinctive features of the ELECTROMIG 400 SYNERGIC is its ability to work on single phase 230V as well as on three phase 400V. The machine recognises the type of connected supply automatically and adjusts its working parameters. This versatility opens completely new possibilities for professionals.
Imagine the situation: you are working on a large structural project in a production hall and using the full power of the welder on a 400V supply. The next day you have to carry out an urgent repair at a customer where only a standard 230V socket is available. With the ELECTROMIG 400 that is not a problem. You can be sure that your tool will cope with the task and offer a considerable part of its power even at the lower supply voltage. This is not only convenience, it is a real saving, you do not have to invest in a second, smaller welder for mobile work. It is one machine that adapts to your needs and not the other way round.
Precision for Thin Materials: ATC (Advanced Thermal Control) Technology
Welding thin sheet, especially material prone to thermal distortion, as in the automotive trade or in the production of stainless steel parts, calls for unusual precision and control over the heat input of the arc. The TELWIN ELECTROMIG 400 SYNERGIC is fitted with the innovative ATC (Advanced Thermal Control) technology, which was created especially for such work.
The ATC system modulates the energy delivered to the weld pool intelligently and gives fast and stable arc ignition together with precise arc guidance at minimum heat input. The result is a marked reduction of material distortion, a lower risk of burn through and clean, smooth welds. For a professional this means higher quality of the finished product, less time spent on work after welding (for example straightening and grinding) and the ability to work on materials even thinner than 1 mm with full control. ATC technology guarantees excellent results wherever every detail counts.
Reliability and Performance in Industry: Premium Class Construction and Components
The TELWIN ELECTROMIG 400 SYNERGIC is a machine designed for hard, daily work in demanding industrial conditions. Its solid metal housing protects the internal components against mechanical damage and dust (protection rating IP23). At the heart of the wire feed system is a professional 4 roll mechanism, which gives smooth and stable feeding of the welding wire whatever its type or the length of the torch. This is the key to keeping the arc stable and the weld sound, especially during long welding sessions.
The high performance transformer and the advanced cooling system give a high duty cycle (for example 400A at 30% for 400V), which allows long welding sessions without the risk of overheating. All components were chosen for maximum durability and reliability. For the user this means the fewest possible service stoppages, a long service life of the machine and the certainty that the welder will cope even with the most intensive production tasks. It is an investment that pays off through years of trouble free use.

Key Features and Benefits
- Advanced TELWIN Synergic Technology: The machine uses intelligent, predefined welding programs (synergic curves) for various materials (steel, stainless steel, aluminium, flux cored wires) and shielding gases. Once the type of material, the wire diameter and the gas have been selected, the welder sets the optimum wire feed speed automatically according to the set current or the material thickness. For a professional this means a sharply shorter time for setting parameters, a lower risk of mistakes, easier access to high quality welds even for less experienced operators, and repeatable results. You save time and material and you cut the amount of rework.
- Dual Supply Voltage (230V/400V) with Automatic Recognition: The ELECTROMIG 400 SYNERGIC can work on a single phase 230V supply as well as on a three phase 400V supply and detects the connected voltage automatically. This unusual feature gives maximum flexibility and mobility. A professional can use the same powerful welder in a workshop with a three phase installation and also out on site or at a customer where only a 230V supply is available. This removes the need to own several machines and gives readiness to work in typical workshop conditions, while keeping impressive power (although the maximum power may be limited on 230V).
- Multiprocess Work (MIG/MAG, MMA, TIG DC-LIFT, FLUX): This is not only a MIG/MAG welder. The ELECTROMIG 400 also offers welding with stick electrodes (MMA) with the Arc Force, Hot Start and Anti-Stick functions, welding by the TIG DC-Lift method with scratch ignition, and welding with self shielded wire (FLUX) without the need for shielding gas. For the welder this means one versatile tool for practically every welding task. Instead of investing in several different machines, you gain a compact solution that copes with varied materials and techniques, which saves space and cost.
- ATC (Advanced Thermal Control) Technology: The ATC function developed by Telwin allows excellent control over the heat input when welding thin materials (for example body panels). Thanks to fast and precise arc control, ATC reduces the risk of burn through and thermal distortion and gives clean, strong welds. Professionals working on car body repair or on thin parts will appreciate the marked improvement of joint quality, the reduction of stresses and the smaller need for finishing.
- Solid Construction and a Professional 4 Roll Feeder: The machine was built for intensive use in hard industrial conditions. The durable housing and high quality components give a long service life and reliability. The professional 4 roll wire feed mechanism gives stable and precise feeding of the wire, which is the key to weld quality, especially with long welding torches and when welding aluminium. For the user this means fewer stoppages, smoother work and the certainty that the equipment will cope even with the heaviest challenges.
- Digital Display and an Intuitive User Interface: The welder has a clear digital display and an intuitive control panel, which makes it easy to select the welding process and the synergic program quickly and to adjust all parameters precisely. Even the advanced functions are easy to reach, which shortens the time needed for setting up. A professional can adapt the settings to a particular task quickly, watch the parameters in real time and save personal programs, which raises efficiency and repeatability.
