this indicates fault 33, on inside of access panel will tell you faulty switch. i believe off top of my head is pressure switch open, this a safety switch to verify that inducer fan is working, several things besides a failed part can cuase this, there is a rubber hose going from the inducer fan houseing to the safety pressure switch, remove hose from fan housing and run a small stick ,wire or torch tip cleaner, down the acces port, calcium builds up inside the port and blocks the sampling of pressure, reassemble and try it, if this works add it to yearly maintenance could need new switch or inducer fan motor, these need to be replaced by a tech, also birds can block flue pipe
Check that the tip is assembled correctly.If is not in properly, it will not arc. Second, check air pressure switch. Sometimes they become stuck from corrosion due to moisture in the air. Test the operation with a tester
Usually it could be one of two things. The first thing to check for is to look at the contact and make sure it is not melted down and ensure its in good shape. The second thing that could do this, would be not enough air pressure. This air pressure is used to blow away the molten metal you are cutting.
yes you need to find and fix the leak, it will show fault if not enough air pressure is there, double check airline connection exterior, and then airline interior after regulator valve also check for are around the regulator,
Air pressure should be no more than 90#s. If regulator cannot handle at least 125#s . Get a new regulater. Sounds like this regulator has a blown diaphram.
Where are you?
Unless you are electrical and modern electronics inclined you may want to find someone with the right training and equipment to service.
Could be a bad power relay.
Thanks,Eric
check the gun lead all the way back to unit,if there is a nic or cut in that lead (main power lead)the unit will not fire,sadly you cannot fix the lead ,it has to be replace with new one,

Press the saftey reset button, if the light goes out it's safe to continue. Sometimes the saftey circuit triggers on noise.
