Welding Inverter MMA-250 IGBT (ST250A)

The STROM MMA-250 welding machine will become an indispensable assistant both at home and in the workshop. It is capable of performing tasks of various purposes and levels of complexity. A powerful and reliable machine from the STROM brand will handle any welding job and deliver high-quality and durable results.

The machine can operate with a power of up to 5500 W. The available diameter of working electrodes ranges from 1.5 to 4 mm. The current strength is adjustable, allowing you to choose the optimal level for yourself in the range of 30 to 250 A. The MMA-250 model can work even at low voltage - down to 180V. Moreover, the inverter's operation will not interfere with the full functioning of other devices connected to the same network.

Lightweight and compact dimensions are definite advantages of the MMA-250 welding machine. Thanks to its compact design, it is convenient to transport, and it can find a place in any apartment or workshop. The machine's additional features also significantly simplify the work process: Hot Start (quick and 100% electrode ignition), Anti Stick (prevents electrode sticking), arc force, forced cooling of power transistors, boards, and internal components to prevent inverter overheating. The machine has the most modern working characteristics and ensures welding quality thanks to the use of the latest IGBT technology.

Welding equipment from the STROM brand is known for its high quality and long-lasting performance. In a short time, it has earned the respect and loyalty of customers.
