Introduction

Changing the kV Setting
The gun’s full voltage setting is 85 kV. Three lower volt-
age settings are possible by actuating the KV1 and KV2
switches. Supply 50 psi (0.35 MPa, 3.5 bar) air pressure
to the KV1 and KV2 ports. Turn the air on or off as
shown in Table 1 to set the desired voltage.
The solenoid valves used to activate the KV1 and KV2
switches must bleed the air out of the lines for the
switches to draw back to the higher voltage setting.
