Relationship between current and voltage of powder spray gun

Related to each other. In powder gun, the voltage is usually provided by the power supply, while the current depends on the voltage of the power supply and the resistance in the system. The resistance of powder spray gun mainly comes from the electrode gap between nozzle and spray gun. Therefore, the relationship between the current and voltage of the powder gun is interrelated, and it is necessary to adjust and control the powder gun according to the specific application and work requirements. Usually, the current and voltage settings of powder gun are determined according to the powder spraying material used, powder spraying process and coating effect to be achieved.
