TELWIN ELECTROMIG 300 SYNERGIC 400V: Professional Power and Synergic Control for Precise Welds
The TELWIN ELECTROMIG 300 SYNERGIC 400V is built for professionals who do not accept compromises on quality and output. The machine selects the parameters for the job instead of leaving you to look for them, so there is less guessing about the final result. This advanced semi-automatic welder, supplied from 400V, brings precision and simple operation into your workshop.
With synergic control, the ELECTROMIG 300 SYNERGIC selects the welding parameters itself once you choose the material, the wire diameter and the shielding gas. You can concentrate on guiding the torch while the machine keeps the arc stable and the penetration correct. Whether you work with structural steel, stainless steel, aluminium or braze weld galvanised sheet, this model gives repeatable results and reduces the need for rework.
Telwin engineers designed the ELECTROMIG 300 SYNERGIC for heavy industrial duty. A sturdy build, an efficient cooling system and work in several processes (MIG/MAG, FLUX, MMA, TIG DC-LIFT) make it a versatile tool. It is a reliable partner for ambitious projects, from heavy structures to precise repair work. The technology raises your productivity and the quality of your output.
Telwin synergy shows in daily work: smooth operation, clear control and weld quality you can show to a customer. With the ELECTROMIG 300 SYNERGIC 400V ACC 3M you get a strong machine and the certainty that every weld is made the same way, which saves your time and material.

ONE TOUCH synergic control: welding was never simpler.
At the centre of the TELWIN ELECTROMIG 300 sits the synergic control system ONE TOUCH LCD. There is no need for parameter tables or long trial settings. On the clear LCD display you select the material (steel, stainless steel, aluminium, galvanised sheet), the wire diameter and the shielding gas, and the microprocessor sets the welding parameters automatically. It works like a welding expert built into the machine, one that knows how to get a clean weld.
This shortens preparation and also reduces the risk of errors, even for less experienced welders. The synergic system matches the wire feed speed to the arc voltage and keeps the arc stable and concentrated throughout the weld. The result is good penetration, few spatters and a tidy weld face, which raises the quality of the finished part and cuts the time spent on finishing. Professionals will value the repeatability and the quick change of the machine between different tasks.
Versatility for every job: from thin sheet to heavy structures
The TELWIN ELECTROMIG 300 SYNERGIC covers a lot of ground. It works in several processesMIG/MAG, flux cored FLUX welding, MMA and TIG DC-LIFT, which makes it useful in any professional workshop. Whether the task is thin body panel sheet, precise stainless steel parts, aluminium structures or heavy steel sections, this one machine handles all of them.
The welder handles many materials, including carbon steels, stainless steels, aluminium and its alloys, and it can also braze weld galvanised and zinc coated sheet (CuSi3, CuAl8), which makes the ELECTROMIG 300 flexible in use. For a professional that means real savings, because there is no need to buy several different machines. The arc dynamics setting (electronic inductance) matches the arc characteristic to the material and the welding position, for good results and fewer spatters.
ATC technology and Telwin quality: welds without compromise
Precision matters above all on thin walled material, where burn-through and distortion happen easily. The TELWIN ELECTROMIG 300 SYNERGIC is fitted with Advanced Thermal Control (ATC). This system controls the heat brought into the weld pool, which is valuable when working with thin sheet. ATC keeps the arc stable even at low current, limits deformation of the material and holds weld quality high.
Besides the advanced technologies, the ELECTROMIG 300 stands for the Italian build quality and reliability the Telwin brand is known for. A sturdy construction, high class components and an efficient cooling system give the unit a long service life and trouble free work even in difficult industrial conditions. Professionals can rely on it day after day on demanding projects, with the certainty that the equipment will not let them down. It is an investment that pays back through reliability, durability and steady quality of the work.
Optimised workflow and ergonomics for professionals
The TELWIN ELECTROMIG 300 SYNERGIC was designed for efficiency and for the comfort of the operator. A clear control panel with an LCD display makes it easy to pick a synergic program and also to fine tune parameters such as free wire length, current rise time (slope-up), the down ramp (slope-down) and burn-back. The option to store your own welding settings speeds up repeated jobs.
The unit comes as standard with a good quality MIG/MAG welding torch 3 metres long (ACC 3M), which gives useful reach and comfort. The sturdy four roll wire feeder mentioned earlier keeps the feed smooth and steady, which is decisive for weld quality, above all with aluminium wire or long cable assemblies. Functions such as 2T/4T, Bi-Level (two current levels) and spot welding with time setting give the welder full control over the welding cycle and let it be matched to the task, which helps ergonomics and reduces fatigue during long jobs.

Key Features and Benefits
- Synergic control ONE TOUCH LCD: based on an advanced microprocessor, the system sets the welding parameters (wire feed speed, arc voltage) once the user selects the material, the wire diameter and the shielding gas on the panel with the LCD display. For a professional this cuts preparation time sharply, removes trial and error and gives correct settings even with less experienced operators. The welds come out repeatable and of high quality, so there is less scrap and faster order completion.
- Welding processes covered (MIG/MAG, MMA, TIG DC-LIFT, FLUX): the ELECTROMIG 300 SYNERGIC welds in MIG/MAG (under active and inert shielding gases), with self shielded FLUX wire (no gas needed), with a coated electrode in MMA and in TIG DC-LIFT with contact striking. This removes the need for several machines, which matters for workshops with limited space and budget. The professional adapts to any task, from thin aluminium sheet to thick steel structures, with a single reliable power source.
- Advanced thermal control (ATC - Advanced Thermal Control): the ATC technology developed by Telwin controls the energy brought into the material, which matters above all when welding thin sheet, for example in vehicle repair or in light structures. ATC limits the risk of thermal distortion and burn-through and holds weld quality high even on heat sensitive material. For the welder this means tidy and strong joints, less finishing work and material saved.
- Sturdy construction and high output: the unit was designed for intensive use in industrial conditions. A strong housing, quality components and an effective cooling system keep it reliable with long duty cycles even at maximum load. The professional can count on stable work for many hours, which keeps production going and orders on time, without worry about overheating or breakdown.
- Precise 4-roll wire feeder and room for extension: the ELECTROMIG 300 is fitted with a professional 4-roll wire feeder that keeps the feed unusually steady and smooth, which is decisive for weld quality, above all with long torches and with demanding wire such as aluminium. The unit also accepts a Spool Gun torch, well suited to aluminium, or a remote control as an option, which adds flexibility and comfort in places that are hard to reach and in special applications. For the professional this means precision, fewer wire feeding problems and adaptation to any task.
- Advanced arc adjustment functions: besides the synergic mode, the welder allows full manual control of the welding parameters, including electronic inductance, which sets the arc characteristic, soft or hard, and affects penetration depth and the amount of spatter. Functions such as burn-back time, slope-up and slope-down give control over the process from start to finish. For an expert these are the tools for fine tuning, for welds of high quality and clean appearance.
