in order to cut the thicker steel just boost the air pressure this will allow you to thourghly blow through the steel. just remember not to turn it up too much. this should do the trick. please rate

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.

Air pressure is probably falling off. This can be caused by several things. The compressor that is too small to keep up is usually no.1. the 1250 is a large unit amd requires a sizeable air source. A way to test would be to connect a compressed air bottle from a welders supply.

check the main lead to the torch,if there is a cut or any hole in the rubber coating it will show fault,the unit uses high frequencey so if the lead has a cut it wont fire up.

Check compressed air pressure is in limits otherwise unit will cut out. Try adjusting the pressure up. also make sure the supply pressure is correct as it may not be your plasma cutter at fault.
