Powder hose correction – procedure
1. Set the powder output value to 80 (%) on the (6) display
2. Put the measuring bag over the gun nozzle and fasten it. Switch on
the gun for 60 seconds
3. Switch off the gun after 60 seconds, remove the measuring bag and
weigh it
4. Annotate the powder output in g/min in the table
Calculate the powder output correction according to following formula:
C1 (%) =
smallest powder output
x 100
measured powder output
5. Annotate the calculated values (C1) for each individual gun in the
table and enter the values to the control unit (therefore, repeat the
steps 2 and 3)
