It is for me. I have found myself renting one a lot over the past year. I have several big projects coming up that will require moving lots of material. So I decided to buy one.
The welder is mostly to be used as a backup generator for the house. But I figured why spend all that money for something that will just sit in the yard.
Also one of the big projects will require a bunch of welding
More to come on those as I get to them.
