816909 ELECTROMIG 400 SYNERGIC 230V-400V WELDING MACHINE TELWIN
Extreme power and industrial flexibility for the most demanding welding challenges! The Telwin Electromig 400 Synergic Base (code 816909) is the 400A multi-process inverter power source designed to guarantee superior performance in industrial and heavy carpentry environments. Thanks to One Touch Synergy technology and 40 preset synergic curves, configuration is immediate and precise on any material. Equipped with a robust 4-roller wire feeder and flexible three-phase power supply (230V/400V), this trolley-mounted machine offers total control of the arc and impeccable results even on thin thicknesses thanks to ATC technology.
Telwin Electromig 400 Synergic Base: Multiprocess Excellence for Industry
The Electromig 400 Synergic Base represents a technologically advanced solution for professionals working in sectors such as installation, maintenance, and metal construction. This three-phase inverter system allows for maximum efficiency in MIG-MAG, MMA, TIG DC-Lift, and brazing, adapting with extreme flexibility to various materials (steel, stainless steel, aluminum, and galvanized sheet metal).
Intelligent Control and ATC Technology
- OneTouch Synergic Adjustment: The system dramatically simplifies the operator's work. Once the material thickness is set, the machine automatically calibrates all welding parameters, while still allowing manual adjustments to customize the bead shape.
- Advanced Thermal Control (ATC): This exclusive Telwin technology ensures excellent welds on thin thicknesses, reducing heat input and minimizing workpiece deformations.
- 4-Roller Wire Feeder: The integrated wire feeder unit ensures smooth and consistent wire feed, essential for using wires up to 1.6 mm in intensive work cycles.
Power Flexibility and Safety
The machine stands out for its ability to operate with dual three-phase mains voltage (230V or 400V), delivering a maximum current of 400A (at 30%) at 400V. The LCD graphic display allows for clear reading of all parameters in real time, while the trolley structure facilitates movement in the workshop.
