I've had one of these welders for almost a year now and have been using it for small stuff until now. It says it does up to 5/16" steel and I used it for my spring perches. It seemed to work pretty well, but I need a 20amp circuit in my garage since it blew the breaker a few times on long beads. Has anyone used this and have opinions? I can post a pic of what the welds look like. I'm not a professional, but I can do "ok".
