So I have a really weird issue that has been going on for quite a while. View the video below for best explanation. I can hear something that sounds shorting in the welder itself and the amps usually bounce around. It's actually sending power to the torch without any input from me. I always thought it was just the amps led display going crazy but it's actually bouncing around because that's what it's sending to the torch. A light tap to the side of the welder usually makes it go away for 5-10 mins but it always comes back. I've cycled all the switches and the machine itself but nothing makes a difference. This happens on AC and DC. Once you tap the welder everything is back to normal and works fine but this shouldn't be happening to begin with.
