I think you are right about the duty cycle because I noticed the longer that bead the worse it got. I have a question about the duty cycle while I'm waiting should i power it off? Or leave it running?
Leave it on. And as far as duty cycle if you're just using it for hobby type work, two minutes of welding is a long time. Weld for 30 seconds, rest for two minutes works out to weld for two minutes and rest for eight minutes.
Practice, practice, practice.
You're machine should do the job. Steve
