The Edon MMA-250S (sometimes listed as ARC-250S or LV-250S) is a popular model in the Edon line of portable, single-phase MMA (Stick) welders. It is designed to offer a good balance of power for both home users and light professional fabrication work. As with other Edon models, the “250S” is a marketing name suggesting a maximum output of 250A, but the actual reliable output is lower for sustained welding on standard single-phase power.
