Kv Readings and Powder Surges

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.
