Standard Maintenance
Note: To be performed while there is no welding occurring
1. Record
ΔP/Static pressure reading from the controller while the unit is operating.
2. Turn off the system. (Blower motor only!)
3. Remove and replace Spark Arrestance filters. (Metal mesh in first track at intake).
A.
Clean the entire inlet plenum to include:
i.
Spark arrestor filter (metallic filter) tracks and cover door
ii.
Inlet Plenum Box (inside and outside)
Note:
Most particulate can usually be vacuumed out; however, if it is high in oil content, it
will tend to smear. If smearing occurs then a commercial degreaser can be used to assist in
cleaning. The cleaning does not have to return the system to new condition, but should be
void of pockets of particulate.
4. Replace metal mesh filters in the filter cabinet with clean ones.
5. Clean out bottom of filter cabinet.
6. Vacuum out the visible material.
7. Turn on the collector and record the new P/Static Pressure.
8. Check for excessive motor/blower vibration.
9. Check overall system for any loose bolts or screws, and also door latches, hinge wear.
10. Wipe off any major hand prints off collector door, control panel that may have gotten there
while doing the service.
11. Clean up any fallen debris from the system service.
12. Observe the welding process when possible and determine if sparks are getting near
the inlet.
Notes:
Any single spark has the potential to cause a fire. Observation is always the best way to
determine if potential exists or if something has changed since the last service.
If the welding parameters change, (i.e. weld wire size, shielding gas mixture, new parts or
supplier) then we should verify spark containment away from the inlets.
