The first thing I would look for is bad air supply. You mentioned trying a different air supply but keep in mind that if you have moisture and or oil sitting in the possibly 25 foot long torch lead even fresh air won't help. A little bit of oil is all it takes to grenade your electrode, even water will a lot of damage very quickly. Signs of dirty air are black or grey carbon deposits on your electrode and in your nozzle, you will see these stains in a swirling pattern following the path of the air.
