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.
