      I am restoring an old Bronco & this was the welder recommended by a guy doing a restoration on Youtube as a good all around 110v welder. Having never welded anything before, I gotta say, I've had it a few months now & the welder has worked great for me. Couldn't be happier with it & as a home hobbist, it has been one of my better purchases lifetime.

      1st 5 Minutes
      This is a great single phase welder at a 3 in 1 combo setup. I was impressed within the first 5 minutes testing penetration and weld quality. So far just ran 20 inches of beads on 1/8 inch scraps I had laying around. I'm impressed. 100% improvement over the 140HD. I would definitely recommend for hobbyists with light duty to medium welding projects.

        This is a true multipurpose welder. I am in the process of restoring a vintage super modified oval track car and this welder has worked perfectly for my welding needs. When buying a welder it is important to stay with a well known brand name, stay away from the warehouse variety and buy AMERICAN.

        The Lincoln Electric LE31MP is a great welder for the hobbyist, DIYer, professional who does basic repairs and joints up to 1/4”, possibly 5/16”, and anyone looking for a portable Flux, MiG, TiG and Stick Welder to do repairs on the road. It comes with all the accessories you need for Stick, Flux, and MiG, and is true MiG as it can run gas. A TIG kit including the wand and an optional foot pedal are sold separately. I found it extremely easy to set up and fun to use and it will be my main welder from this point forward. As far as complaints go, only a few minor ones. I had to clean up the threads on the MiG spindle as it had some extra material left over from the factory threading, and it didn’t come with the TIG kit. All in all I think it’s a great little welder and a good value. You probably can’t beat it at this price range, and MiG is so much more enjoyable than Stick in my opinion. That alone is worth some extra bucks. See my YouTube video for an unboxing and live welding footage.

        Great welder, so far so good
        similar to my weld pak 100 that has worked great but has more features in a lighter package, if it works and last like my 100--it will be a great welder, just a little on the pricy side
