Seven years ago I was looking to buy a MIG/flux core welder, I did some shopping around and decided on the Lincoln 140. It runs on standard 120V household current. I purchased it from a local Lincoln dealer that can service it if something should break down.. it was very easy to set up and I practiced welding on scrap metal for several days plus I watched some welding videos on YouTube. I started welding using the flux core wire first (no gas) first on the floor pans of my 65 GS project. I found this welder very easy to use and the welds were great. then I switched to MIG (Gas) to install the right rear quarter and other exterior work, its not as easy to MIG as to flux core but practice I did and it came out great... the only drawback is switching from MIG to flux core, you have to reconfigure the unit each time, and since I do a lot of both kinds of welding now it can be very time consuming, so I decided to leave the Lincoln a MIG welder and purchase just a flux core welder. I found a plain flux core welder in the Northern Tools Catalog its a Ironton 125 it got good reviews so I called and they said if I was not happy I could return it, so I spent $130 on sale+$20 for a 2 year warranty, no tax and free shipping right to my door !!! I've been using the welder for 4 months now welding floor/trunk pans in a 64 Riviera and other jobs around the garage and its working fine. its definitely not the Lincoln but it does the job. I know nothing about TIG welding so I will leave that up to another member... Tony G
