Im going to cut to the chase. The Migweld 140 weakness is its wire feed mechanism, as is the case with all low end MIG welders. At the beginning of the first 10 lb spool it was fine but gradually the tensioner required more and more turns on the wing nut to get it to feed consistently. On the second 10 lb spool it got to the point where no mater how tight the tensioner was set the feed roller would just turn and turn and turn and feed no wire. I was in the middle of a project that could not wait so I was forced to figure out something to get the wire feed to stop slipping. So after much trial and error here is what ultimately fixed the wire feed mechanism.
Problem 1: The hinge point on the tensioner swing arm was spreading open allowing the whole arm to shift out of position. To fix that I took a piece of 3/4" 16 ga square tubing, cut a 1/2' piece off the end, cut one of the side off, and spread the remaining u open a bit to allow the home made clip to slide over the hinge part of the swing arm. This kept the swing arm from opening.
Problem 2: Tightening the wing nut would push the bearing forward because the bolt would start leaning towards the rear of the welder aiming the spring forward. I just put a large area washer under the spring to keep the bolt vertical so that the force of the spring was sent downwards not forwards.
After those modifications it does not take anywhere near the turns on the wing nut and the drive does not slip at all. Now it sounds like proper bacon frying not... smat to pop. pop. pop. that it was doing. All in all its a great welder now, five stars if it were not for the fact that I had to reengineer part of the wire feed mechanism.
Now let's get on with the two year review. Unfortunately it's starting to break down... A few months after purchasing the machine I noticed a problem with the gas regulator. The pressure guage and flow guage both stopped reading acurately. After some more weeks the bezels with the units on it inside the guage warped and the needles no longer moved at all. This was not that big of a deal, new guages can be bought for relatively cheap. I replaced them. Another minor inconvenience; the plastic bezel on the front of the machine has started to warp, probably from use outside in the sun. Now for the real problem: the wire feed mechanism no longer works. That is to say, the drive still turns, but the wire does not really feed. No amount of tightening or loosening of the thumb screw solves this. I've tried a fix mentioned by another reviewer here, but it still will not feed reliably. Also, odly enough, increasing the voltage now seems to speed up the wire feed, I'm not sure why. Needless to say, I can no longer use this machine as it was intended. A reliable wire feed mechanism is as crucial to the operation of a MIG welder as the power cord is. I've tried contacting Longevity with this problem but they haven't responded (another nail in the coffin, no company support.) It's my understanding that Longevity learned about this problem, and silently re-engineered the wire feed mechanism on newer models of this same machine. Which, I suppose is good for new buyers, but not so good for me.
The good news? The spool gun still works, for now, as it has it's own wire feed mechanism. HA! Take that, China. Anyway, this thing will become a dedicated aluminum MIG welder, and I've taken the defunct machine as a sign to upgrade to a 220v Miller MIG unit. Welding is fun, and learning on this machine has been easy, but don't expect it to last too long.
This sucker packs a punch heat is not an issue and I find myself lower in the dial than other welders of this class.
Rheostat amperage control.
High quality feed mechanism also very smooth. big name welders have been getting worse I feel in this area but longevity actually improved this one based on poor reviews early on from what I can tell, says something for the company.
Spool gun option!!
Thought mine was broke because I set the amperage all the way down and wire speed all the way up and it was feeding very slow. Turns out below 4 ish on the amperage dial it automatically limits wire speed smart but threw me for a loop.
Big and heavy was bulkier than I thought not really a con but didn't fit where my old red welder was.
Regulator hose a bit stiff and short. Cheap regulator but no worse than any other brand.
Will pop my 20 amp breaker without even being turned all the way up. Although that's because it's a hot machine and I never need it that high. However if I were to weld aluminum I'd upgrade the outlet to a 30 amp.
