Telwin Mastermig 305i Base: Professional Multiprocess with 4-Roller Wire Feeder

The Mastermig 305i Base belongs to the new generation of Telwin inverter welding machines, designed to offer maximum operational flexibility (MIG-MAG, MMA, TIG DC-Lift) and superior energy efficiency (86%). It is the ideal tool for professionals working on different materials such as stainless steel, high-strength steels, and galvanized sheets.

Fluid Drag and Digital Control

  • 4-Roller Wire Feed Unit: Ensures absolute stability in wire feed, essential for intensive work sessions and for the use of aluminum or flux-cored wires.
  • Dynamic Display: The intuitive interface allows you to view and set all welding parameters with extreme precision in real time.
  • MMA Synergic Regulation: Facilitates arc striking and fluidity thanks to the automatic management of Arc Force and Hot Start based on the type of electrode selected.

Industrial Reliability and Protection

The internal construction follows the "ventilation tunnel" philosophy: the cooling airflow is channeled to avoid direct contact with the circuit boards, preventing failures caused by metal dust. The machine is designed to operate with motor generators and tolerates wide variations in mains voltage (+15% / -25%).
