I'm using a recently purchased Maxstar 200 DX. When I am trying to use SMAW process with the output on "I", there is a reading of 0.0 V on the output. I was using the machine the night before and it was working just fine, but could not strike an arc the next morning and noticed I had no output voltage. Any suggestions? I am fairly electrically inclined and would need to resolve the issue on my own because I work on a ship. The machine is practically brand new! HELP!
