The 140c model is NOT the standard "Lowe's" or "Home Depot" store model Lincoln. Those are the "140T" models and they are NOT AS GOOD AS THE 140c. My review will discuss the 140c model. The difference between the two is that the 140c model is a bit more expensive, but has a "continuous" rheostat voltage control knob. This allows one to find the "sweet spot" for welding certain thicknesses of metal. The 140T model has a "tapped" voltage controller which is inferior.

The 140c can weld 1/4" steel plate no problem. If you know what you're doing and have some experience in welding that is, it is not hard to "tweak" the machine into doing what you want it to do. In fact, I regularly use it to weld 3/8" steel handgun targets. Also, another key point is that one needs a 120v wall outlet that is a minimum of 25amp service. Using a traditional RV 30A outlet with a simple $8.00 plug adapter would work perfectly! However, most people do NOT have a 25A or 30A service outlet at their homes. However, many residential houses all have have 20A service outlets, that will pretty much work for most metal. Only time even the 20A outlets trip the breaker is when you turn the voltage rheostat up to the high range and then your breaker will trip regularly. Especially if you're running an extention cord from the outlet to the machine. I try NOT to using an extension cord. Longer the cord, the increase in resistance, thus decrease in voltage to the machine. Now if one only has a regular 15amp 120v outlet at their house, the welder will work, but not on a "high" setting, therefore it will limit one to welding thinner stuff. Thinner metals do not require the "higher" voltage or wire speed settings that the thick stuff needs.

Just got the machine today from a local Lincoln dealer $659 (he threw in a stainless steel wire brush and half a dozen extra .035 tips for free) to fix a broke piece of cast aluminum on our round bale wrapper. Well, the machine performs well when it's not jamming. Needless to say, if you're going to weld aluminum with this machine, for the love of God, buy the Lincoln 100SG spool gun! I would've bought the spool gun but the dealer didn't have it in stock and I had to fix this part immediately so I did my best trying to push .035 aluminum wire though a non-Teflon liner. Like I say before, when the aluminum wire wasn't jamming (birds nest), breaking, or causing excessive burn back which made me go though quite a few tips, it really made some nice welds. I did manage to repair the damaged part (not my greatest weld job do to aluminum wire feed difficulties) and it held up to allow us to finish the job we started ... and it's still in tack after we finished ... so all in all ... this little Lincoln welder saved the day.

Good quality welder ... 3 year warranty ... and it's a freaking Lincoln ... just wish the Lincoln K520 cart was a little cheaper but is capable of holding a much larger bottle of gas.

BTW ... this was my first time MIG welding aluminum ... I prefer TIG ... but this was a neat experience and really wasn't to difficult ... minus to wire feed problem but that's to be expected.

Last but not least ... being able to plug this sucker into a 120V outlet is extremely handy and should make itself very useful around the farm for small repairs.

I would've given this 5 stars had they bundled a liner with this unit that was aluminum MIG wire friendly!

This is my third mig welder and my second 115 volt mig. My first mig was a 115v campbell hausfeld that was generally poor in every way even for a beginner like I was.
The next time I needed a mig I got a lincoln 180C and it is an awesome machine but I have needed a good 115volt welder for work where 220 is not available for some time and so I got this 140C. A few things I have noted between 140C and 180C = the 180C has a much smoother stable arc for welding thin steel. the hardware used on the electrical connections are better on the 180C as is the ground clamp. The 140C does everything it is supposed to and does it well, I would go as far as to say that if it is not best in class it is second place at least. I would also tell any prospective buyer to go straight to the 220 Volt lincoln 180C because it is an outstanding welder and will weld everything a smaller welder can yet has the power to weld thicker steel.

This is the best price I've found anywhere for this welder. Great machine. The standout that makes it superior to the ones at Home Depot or Lowes is that the dials don't step up notch by notch. You can adjust it hair by hair. Honestly, since I'm new to welding that hasn't been a big benefit to me. I'm sure more experienced welders appreciate the ability to fine tune, though, and perhaps one day I will, too.

If you're looking to get into welding small to good size projects, this is for you. I am welding about 250 feet of iron railing using solid 1/2 rod for the balusters. This machine hasn't stopped for a cool down cycle even once, and the welds are solid as...well....iron.

I didn't take any classes, only watched videos online and asked people questions. Simple chart inside the lid tells you what settings to use. Easier than I thought it would be.

You do need a 20 amp circuit to run this machine. I haven't tried it on a 15 amp, but from everything I've read it will pop 15 amp circuits pretty easily.

ADVICE: If you're doing mig, go ahead and get a bigger 60 cubic foot bottle of Argon/CO2 mix. The little 20 cubic foot bottles run out fast, and cost almost as much to refill. At my local place, 20cf refill is $20. 60cf refill is $26. The bigger bottle costs more, but it will pay for itself in lower refill charges. And I get my wire at Harbor Freight way cheaper than brand name wire, and it hasn't hung up on me.
