Steady arc & perfect bead, right out of the box
I acquired the MM-141 for relatively light fabrication work in a small shop, and it's been a real champ. The only open circuit we have for this unit is a 20 amp, so our previous 110 welder had trouble maintaining a steady arc and tripped the breaker all the time. The 141 on the other hand has been perfect from day one; the arc is strong and steady. The build quality is also much better than previous gen MMs, such as the 135 or 140.
We took it out of the box, hooked up the gas, loaded the wire, plugged it in, and bam: perfect weld. Didn't even need to dial it in.
ProsSolid build quality. Rock steady arc. Dead simple set up. Even works on a 20 amp circuit. Easy to carry, which is a nice bonus.
