Hello, I work for an industrial manufacturer who has several different Hypertherms in service. I am the resident electrician but somehow have been tasked with servicing the plasma cutters as well. I have run across a problem I've never encountered and was wondering if anyone knew where I could find a schematics or electrical diagram or help me solve the issue. Okay. So the unit is throwing an ERROR CODE 0-22 which is NO GAS input, but I have checked the gas line and the dryer and I have sufficient airflow. What I don't know how to check is the Pressure switch or Transducer. If I just knew how to test to see if they were working, I might be able to find the problem. Thanks a bunch.
Miles.
