Maxmech Inverter Welding Machine MMA-250 250AMP

The Maxmech Inverter Welding Machine MMA-250 250AMP is a powerful stick welder designed for heavier-duty welding tasks than its 200AMP counterpart. Like other inverter welders, it uses advanced IGBT technology for efficiency and portability.1It’s important to note that Maxmech, like many manufacturers, may have different models under the “MMA-250” designation (e.g., standard, $\text{S}$, or $\text{PRO}$ versions) or multi-process welders like the $\text{TIG/MMA-250}$. The specifications below represent a common range for the single-phase $\text{MMA-250}$ model.Key SpecificationsFeatureSpecification (Typical Range)Welding ProcessMMA (Stick Welding) / $\text{DC}$ Arc Welder (Some models are $\text{TIG/MMA}$ combo)TechnologyAdvanced IGBT InverterInput VoltageSingle Phase $\text{AC } 220\text{ V} / 230\text{ V}$ $\pm 10\%$ to $15\%$Frequency$50/60\text{ Hz}$Max Output Current$250\text{ A}$Current Range$20\text{ A} – 250\text{ A}$ (Some variants have a max rated output of $180\text{ A}$)No-Load Voltage$59\text{ V} – 78\text{ V}$
