Super happy with the purchase. Spent the weekend cutting 1/8" and 1/16" steel for a project I was working on. It's definitely better than using a meat grinder! Cuts cleaner than a utility knife and is cheaper to run. I cut about 10 linear feet of metal total and the tip is still like new. I am connected to 220V and have not tested the machine on 120V. I bought some spare heads just in case. Now that I trust flaring, I am thinking about buying a flaring welder (gift).
