Hey Guys- Hoping someone has seen this before and knows the cause. So the air stays coming out of torch. If I disconnect the air and plug back in it shuts off for a second and then turns back on. If I unscrew the retaining cap on the torch it shuts off and stays off, as soon as I tighten the retaining cap the air comes out again. Tried all different air pressures and doesn't change behavior. Thought maybe it was solenoid in flexcut but it is shutting it off and on just at the wrong times. Also tried different tips, caps and nozzles and acts the same. Thoughts?
