Try cleaning the ground inside the welder. and make sure you have a good power supply ie. power cord. check the transformer for continuity and clean all the contacts ( are you sure the power inverter diodes are only passing current one way and are not "open" )

Open the cover (only after a day of not being plugged in).
Check the airline that comes in through the back of the case.
The air line has either fallen off or has a hole in it.
If you are a technician and don't mind working with thousands of volts of electricity that is inside the case, then and only then can you plug it in. Safety First. Rember the voltages inside this unit are lethal. It will not give you a second chance.
If you feel you are qualified, then plug it in and start it up, use it as normal, while at first watching from a 2 meter distance, you may immediately see and/or hear where the noise is comming from.
DO NOT under any circumstances put your hand or hands inside the box while it is live.
Try running a WOODEN stick (at least a foot long) along the length of the airline inside the case and around the valve as it enters the case. The sound should change in pitch when you find it.
If you think you have found it, DO NOT touch anything inside, until you have both DSCONNECTED THE UNIT from the power source and WAIT ONE DAY before putting hands inside the unit. Any storred or residual energy will have discharged by this time, making it safe to work on. Safety first. The voltages inside are lethal. This aplies to all Plasma Cutters. Good luck.
