Why is Constant Current Control Essential for Electrostatic Powder Coating?

Voltage is just one part of the story. Many operators focus on kilovolts, but amperage actually dictates how powder behaves in the air. When you use traditional constant voltage systems, the current fluctuates as the gun moves closer to the part. This instability causes uneven thickness and wasted powder. Constant current control changes the game. It locks the flow of ions at a precise level, regardless of the distance…….[..]
