MASTERMIG 400

Telwin 827004
MIG/MAG welding (wire feed) F4 · Semi-professional

The Telwin MASTERMIG 400 is a transformer-based welding machine designed for intensive industrial use and heavy-duty workshop applications. Thanks to a maximum current of 400A and a robust electromechanical power source, this machine guarantees consistent reliability on thick materials. The choice of traditional step-regulated technology, devoid of complex synergic controls, makes it an extremely durable and easy-to-maintain solution, ideal for metal fabrication, shipyards, and commercial vehicle repair shops. The weight of over 100 kg reflects the solidity of its internal components, engineered to withstand demanding work environments and prolonged production cycles.
