Reasons your control gun is not showing any reading of Kv could be any one of the following:
- Loss of power to gun
- Faulty circuit board
- Internal gun failure
A few causes for powder surging from the gun includes:
- Insufficient supplemental air to ensure the powder is in suspension as it moves through the hose.
- Improper seal between the powder injector and the lift tube in the gun feed hopper.
- Blockage from buildup or impact fusion. Check powder hose, gun tube, and pump insert.
