I obtained a Blue Point (Snap-on) plasma cutter that will not start. When the trigger is depressed, the air comes on but it will not start an arc. I feed it with a Quincy 2-stage at 80 psi and had replaced all the consumables and made sure I had a good ground attached close to the cutting point. When the trigger is depressed and held down, the unit cuts out after about 5 seconds. I tried contacting Snap-on and was told this is a discontinued model and they did not service it (that really surprised me as I thought Snap-on supported all their products) and was given another vendor to try. So far I've been to Chole, TWSA, Airgas and Lincoln with no resolution. I opened the side panels and watched the inside components as the trigger was depressed. There are several relays in the unit that have a clear plastic case and all of them except one operated when the trigger is depressed. I'm wondering if I have a bad relay but I don't have enough knowledge on if all of them are supposed to work at the same time. I sure could use some help from those with more experience with this older equipment. I suspect there must be some of these units around since Snap-on probably sold more than just one to me. The model is a 115 v, 25 amp YA2225.
