I have this with my Forney 140 magnet core and I love it. I've only used it twice and it did the job for me. I am not an experienced welder. I took a basic welding class last fall, which was basically just a pole, so I wanted to get my own little pole machine. I've used it with a 7018 and a 318 rod and it looks like I know what I'm doing so can't ask for more. I was very surprised at how well 318 stainless steel worked as I had never worked with stainless steel before.
