Operation
OptiGun 2-A(X) (GA02) Automatic powder gun
Selecting powder output volume
1. The powder output volume is selected in reference to the de-
sired layer thickness. The selection is done by the
+
or
-
keys
on the control unit. For the beginning, the standard adjustment
of 60% is recommended. The total air volume is thereby kept
constant automatically
2. Check the powder fluidization
3. Point the gun into the booth and press the gun switch
Selecting electrode rinsing
1. Select the correct electrode rinsing
(setting range: 0-2,8 Nm³/h, default value: 0,2 Nm³/h)
(setting range: 0-1,65 scfm, default value: 0,12 scfm)
2. Adjust the powder cloud with a test object
If flat jet nozzles are used:
3. Unscrew the sleeve nut approx. 45°, so that the flat jet nozzle
(or its extension) can be moved slightly
4. Turn the flat jet nozzle to desired axis direction
5. Tighten the sleeve nut firmly again
If round jet nozzles with air rinsed deflectors are used:
6. Replace the deflector (Ø 16, 24 and 32 mm are supplied with
the gun)
Rinsing the powder hose
If lengthy downtimes take place, the powder hose is to be cleaned from
powder. Observe the following steps:
1. Remove the powder hose from the hose connection on the in-
jector (see the operating instructions of the used injector)
2. Blow through the powder hose with compressed air. Powder
hose can be cleaned by tearing off a foam cube from the pack-
ing material, and blowing it through the hose with compressed
air. Therefore, use our air gun, which is specially designed for
this operation (order no. 346 055)
3. The foam cubes can be ordered in sheets of 100 pieces (order
no. 241 717)
4. Fit the powder hose again to the hose connection on the injec-
tor
