The *MM650S* is a heavy-duty *DC inverter arc welding machine* — basically a super powerful stick welder for industrial and professional use.
*Key specs you'll see*
- *Model*: MMA-650S, usually part of “Super Power IGBT Series”
- *Type*: MMA = Manual Metal Arc, i.e. stick electrode welding
- *Current range*: 20A – 650A. That 650A rating means it can run big 5.0mm rods and handle thick steel
- *Input*: Most versions in Uganda are 1-phase 220V, 50/60Hz, though some Weldman models use 380V 3-phase
- *Tech*: IGBT inverter. Makes it lighter, more efficient, and gives stable arc vs old transformer welders
- *Features*: Hot Start for easy arc ignition, Arc Force to stop electrode sticking, Current adjustment knob, digital amp meter
- *Cooling*: Air-cooled fan
- *Protection*: IP21S rating – okay for workshop/indoor use, not rain fb10ee5e
