TELWIN ELECTROMIG 300 SYNERGIC: professional 400V power and synergic precision for first class welds.
TELWIN ELECTROMIG 300 SYNERGIC 400V is an inverter welder built for demanding professionals and for ambitious hobby users who do not accept compromises. If you weld different materials every day and expect clean results with short setup times, this model answers that need. Instead of slow trial and error with the settings, the synergic control of the ELECTROMIG 300 leads you step by step to a good weld, every time.
ELECTROMIG 300 SYNERGIC runs on a strong three phase 400V supply and offers welding current up to 270A together with microprocessor control. The synergic programs set the welding parameters automatically once you enter the material thickness and the wire type. That means fewer test runs, less wasted material and a shorter path from preparation to the finished joint. Carbon steel, stainless steel, aluminium or MIG brazing of galvanised sheet, the machine adapts to your requirements with a stable arc and little spatter.
Versatility is the second name of the ELECTROMIG 300. Besides the dominant MIG/MAG method, the machine also welds with FLUX self shielded wire without gas, with covered electrodes in MMA and in TIG DC-LIFT, which turns it into a welding centre for any workshop. The ATC technology (Advanced Thermal Control) allows precise welding of thin material and lowers the risk of burn through and distortion, which counts in sheet metal work and on details that need a clean finish. The clear LCD display and the intuitive control panel keep even the advanced functions within reach, so you can concentrate on running the torch.
With TELWIN ELECTROMIG 300 SYNERGIC you invest in reliability, precision and output that translate into real savings and better quality in your projects. It is not only a tool, it is a partner in daily work that handles every task, from heavy structures to fine detail. See for yourself how power combined with synergic control changes a workshop.
Advanced features of the TELWIN ELECTROMIG 300 SYNERGIC 400V
Synergy within reach: ONE TOUCH LCD SYNERGY technology
The ONE TOUCH LCD SYNERGY technology in the ELECTROMIG 300 is a welder that thinks with you. Thanks to the stored, optimised synergic programs (25 curves), you select the material (steel, stainless steel, aluminium, MIG brazing CuSi/CuAl), the wire diameter and the shielding gas, and the machine sets all the key parameters automatically: arc voltage, wire feed speed and arc dynamics.
For the professional this saves a lot of time and gives repeatable welds of high quality regardless of operator experience. Trial and error is over. The intuitive LCD display guides the user step by step and shows the chosen settings. Experienced welders can still correct the parameters by hand and match the arc characteristic to their own preference and to the demands of the application. It is a combination of simple operation and full control.
Precision on thin sheet: the ATC system
Welding thin material, above all steel or aluminium that distorts under heat, is a demanding job. TELWIN ELECTROMIG 300 SYNERGIC with ATC (Advanced Thermal Control) changes the rules. This system controls the energy put into the weld pool precisely and lowers the risk of burn through, distortion and stress in the material.
How does it work in practice? ATC gives a stable arc even at low currents, which is the key when joining thin sheet. The system optimises the shape of the current pulse, so the pool solidifies faster and the heat affected zone stays small. The result is smooth, clean welds without distortion, also on body panels and on parts that need high precision. That means less finishing work and a professional look on every detail.
Material flexibility: from steel to MIG brazing of galvanised sheet
TELWIN ELECTROMIG 300 SYNERGIC is at home with many materials. Thanks to the dedicated synergic programs and precise manual adjustment, the machine welds carbon steel and stainless steel (INOX) as well as aluminium and its alloys. The synergic curves for aluminium take its high thermal conductivity into account, which gives proper fusion and lowers the risk of porosity.
The ELECTROMIG 300 is also a good tool for MIG brazing with CuSi3 or CuAl8 wire. This matters on galvanised sheet, for example in automotive work, because the parts are joined without destroying the zinc layer, which prevents corrosion. The lower process temperature compared with classic MIG/MAG welding also limits distortion of thin sheet. This material flexibility makes the ELECTROMIG 300 useful in any modern workshop.
Full arc control: advanced settings for experts
Although synergy in the ELECTROMIG 300 SYNERGIC clearly simplifies the work, Telwin did not forget experienced welders who want to personalise the process. The machine offers a set of advanced adjustments that let you tune the welding arc to specific requirements.
Available to the user are, among others: electronic inductance, which affects arc stiffness, penetration depth and the amount of spatter; wire burn-back time, which stops the wire sticking to the contact tip at the end of the weld; current slope-up and soft start of the wire feeder, which give a smooth start and stable arc striking. For the MMA method there are also Arc Force (arc dynamics), Hot Start and Anti-Stick. This level of control gives good results in typical workshop conditions and with every material.

Key features and benefits
- ONE TOUCH LCD SYNERGY control: This technology changes the way welding parameters are set. You choose the material, the wire diameter and the shielding gas, and the microprocessor selects the right voltage, wire feed speed and arc dynamics. For the professional this cuts preparation time sharply, removes setting errors, gives repeatable welds of the highest quality and allows full attention on torch work, even when the tasks keep changing. It also lowers material and energy use, which improves the margin on every order.
- Several welding processes (MIG/MAG, FLUX, MMA, TIG DC-LIFT): The ELECTROMIG 300 is a true multi process machine. Besides standard gas shielded MIG/MAG welding, it runs self shielded FLUX wire in places that are hard to reach, covered electrodes in MMA with Arc Force and Hot Start for easier striking and a stable arc, and precise TIG DC-LIFT welding with contact striking. One machine instead of several saves workshop space and money and keeps you ready for any welding task.
- ATC technology (Advanced Thermal Control) for thin material: The ATC system is the key to clean welding of thin sheet (in automotive work or in light structures). It controls the energy fed into the weld pool intelligently and prevents overheating, burn through and distortion of the material. For the welder this means clean, smooth welds on material even below 1mm thick, less rework afterwards and a good appearance of the finished part.
- Advanced arc adjustment: Professionals will appreciate the option to fine tune arc parameters such as inductance (arc dynamics), wire burn-back time, soft start of the feeder or current slope-up. The welding process can be matched to a specific material, welding position or application, which gives better control of the pool, less spatter and higher joint quality.
- Solid power and output (400V, 270A): The three phase 400V supply and a maximum welding current of 270A at a high duty cycle (180A @ 60%) give the power needed for thicker material and demanding structural projects. Steady operation under heavy use keeps production running and shows that the welder handles the hardest tasks, which counts in professional industrial and workshop applications.
- Intuitive interface with LCD display: Despite the advanced functions, operating the ELECTROMIG 300 is simple thanks to the clear LCD display and a logically arranged control panel. The graphic display shows the chosen parameters and makes navigation through the synergic programs and the manual settings easy. Training time is short and less experienced users reach professional results quickly.
