ELECTROSTATIC COATING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an electrostatic coating apparatus which prevents the action of an operator to keep an electrostatic spray gun unconsciously apart from an optimum position for coating during electrostatic coating. SOLUTION: When a load current which changes approximately in proportion to the change in a spray distance is detected, and the load current is equal to or below the threshold which is the maximum load current within an optimum range of the spray distance, the operator is informed by the lighting of an alarm lamp or an alarm sound that the spray distance is out of the optimum range.
