After cleaning, the torch is moved from the clamping position (1) over the injector (4) for injection with the
gas nozzle (2).
In this position, the gas nozzle (2) actuates the roller lever (3) so that the directional valve (7) is switched.
The compressed air is no longer supplied to the stroke cylinder but to the injector (4).
See option Fig. 12 Pneumatic plan on page EN-17
When the control signal, stroke = 1, is set again, injection starts. The air flowing through the injector (4)
creates a vacuum in the suction hose (5). The anti-spatter fluid is sucked in from the anti-spatter agent tank
(6) and added to the circulating air.
