  • Good welder I recommend it
Very nice welder. I’ve used it all summer on small projects and have been very happy. It has easy high freq starts, good controls and the auto setting are pretty close without fussing around a lot. I still haven’t figured out the pulse feature or found it too useful but maybe that will come with working with it more. I wish Lincoln had a better finger control for current but see a few aftermarket ones that I’m thinking about…. Maybe Christmas 🎄 ... show more

  • Very happy with this welder
I’m just learning TIG welding but so far this machine is very impressive, easy to use, and what seems like quality components.

  • Quality
An excellent welder for the price. I don’t have too many big projects, yet. But I did have a couple small jobs and Tig welding is what I prefer and it did the job just fine. Excellent machine and comes with a bunch of excellent accessories.

Great welder!

  • It will weld
The miller welder at work cost ten times as much but I'd say it's only twice as good so this gives you better bang for your buck

  • Worth the investment
Excellent Welder. Practicing for pipeline and wanted to make sure beads were consistent with welders on the field so this is perfect.
