  • Weld Red
Everything was as expected, great quality, handles make portability great. Fans are a bit loud at times but they turn down when not in use. Decent assortment of AC/DC and GTAW/SMAW setting and very accurate arc control. Comes with a 30 amp to 110v adapter so can be used easily.

  • 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

  • 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.

  • 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.

  • 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
