I had a real similar welder to that one to start off with, it came out branded "Astro" and were one of the 1st marketed to hobbyist and homeowners, I remember them being advertised in magazines like popular mechanics for $129.95. mine was branded "MAC" and cost me a whole lot more. I welded what I could with it for a while, wound up burning out the transformer.
I then moved onto a Century brand machine, just as the 110v lincoln's and millers were coming out. I burnt that one out faster than I did the old Astro.
I decided that I was done with 110v MIG welders and bought my Millermatic 185 back around '97-98.
I have never had a minute's issue with it, I only wish that I would have bought this one 1st. I paid less for it brand new, than I paid for the 1st 2, used
The MAC came off the tool truck as a "repo" supposedly I paid what the original guy still owes at the time. Didn't realize then that it was the machine it was or I'd have passed.
The century was a garage sale find, a Grandpa bought it for his 2 grandkids that took a little welding in high school. Supposedly the kids used it once or twice and then it sat. It looked like the description, at the time.
Both of these burnt up either building, or rebuilding, (1 of each) trailers
Now a days I'd consider a lincoln or hobart or a miller 110v for smaller jobs.
