Be those that were constructed by ground Ri, spark is less likely to occur with a ignition capability when the resistivity of the grip touches the grip people since it is 10 4 Ωm or more, moreover, the resistivity is 10 6 Ωm or less.
There is an effect that the lamp and the worker are not charged.

塗着するようになっている。[0010] high voltage cable 5 is connected to the negative pole of the grip 2 a high voltage generator, an air hose 7 connected to the connection paint hose 6 and co down presser to the paint tank
Are connected, and a lead wire (not shown) is connected and grounded. A high-voltage cable 5 coated with an insulating material is inserted into the grip 2 as shown in FIG. A high voltage is applied to the electrode provided on the gun tip 4 via a high resistance in the extension 3, and further, a paint passage 8 and an air passage 9 connected to the paint hose 6 and the air hose 7 are formed. Then, each reaches the gun tip 4 through the extension 3, and the paint particles atomized by the air are charged by the electrode and applied to the object to be coated.
【００１１】ここで、グリップ２の素材は電気抵抗が小
