6.4 Maintenance
6.4.1 Spray Head /Parts Maintenance:
1.
Spray Head:
The outer body of the spray head requires occasional cleaning to
eliminate any possibility of metal dust that could cause arc shorting between the
contact tubes. A small stiff brush or knife blade can be used to scrape off the
accumulated metal dust, the head is a plastic material so don’t scrape away head
material. Daily cleaning is recommended, at this frequency all accumulated
material can usually be wiped off with a rag, eliminating the possibility of head
damage.
2.
Contact Tube / Tips
:
During operations the wire will carry dust, dirt, lint,
etc. into the liner system and it will accumulate behind the contact tip in the
contact tube. This can cause enough friction to impair wire feed. Remove the
contact tube from the head, then remove the tip from the contact tube. Clean the
tip manually then use an air blow gun and clean the contact tube. In extremely
dusty conditions this should be done once a day. These items are considered
consumable parts and will require replacement due to wear.
3.
Air Nozzles
:
The air nozzles do not normally require maintenance, except to
keep alignment as shown in the prior sections of this manual. However, if the
nozzles are aligned, and the spray is erratic or uneven, remove the air nozzles and
with an air blow gun clean the holes by reverse blowing through the air jet holes.
Visually inspect the nozzles for obstructions prior to reinstallation.
