Pressure Relief/Work Interruption; Optimizing The Powder Cloud For Coating; Reproducible Setting Of The Nozzle Position - WAGNER PEA-C4-HiCoat Translation Of The Original Operating Manual

VERSION 05/2019

7.4.3 PRESSURE RELIEF/WORK INTERRUPTION

Carry out the work steps as described in the "Pressure relief" chapter:
– if pressure relief is required,
– if the coating work is interrupted or stopped,
– before the device is cleaned on the outside, checked, or serviced,
– before the spray nozzle is installed or cleaned.
7.5

OPTIMIZING THE POWDER CLOUD FOR COATING

Procedure:
1. Switch on the high-voltage generation and the powder feed.
Note:
To minimize wear on the wearing parts, the total air volume should be below 5 Nm³/h.
The atomizing air should be adjusted for the:
– flat jet nozzle to 0.1 Nm³/h
– round jet nozzle to > 0.2 Nm³/h
2. Adjust the powder quantity and the powder speed on a test piece.
7.6

REPRODUCIBLE SETTING OF THE NOZZLE POSITION

– For a horizontal powder cloud, the flat jet nozzle is set so
that the protective wedge is in the 0° position.
– When attaching a round jet nozzle, we recommend turning
it to the 90° position to achieve a better spray pattern
(the protective wedge is now in the vertical position).
It is possible to change this position as needed for special
applications.
On the nozzle body and electrode holders, there are X markings.
The position can be changed as required in 15° increments and
later reproduced.
The union nut has to be removed for exact positioning.
An adjustment tool is provided for the flat jet nozzle.
It permits turning the flat jet nozzle without damaging the
electrodes and without removing the union nut.
The union nut only has to be slackened.
