JTMAX PROMIG-250ET 3-in-1 Multi-Process Welding Machine

It is a versatile, inverter-based professional welding unit that supports mig (gmaw), mma (stick), and tig (gtaw) processes. key front control panel features dual digital led displays: the left screen monitors current (amperage/wire feed speed), and the right screen tracks real-time output voltage. three analog dial knobs: left dial: adjusts mig welding current, mma welding current, or tig welding current. center dial: regulates mig voltage or mma arc force settings. right dial: controls mig inductance (crisp/soft arc characteristics) or mma hot start parameters.
