4.6 GENERAL TORCH MAINTENANCE
Cleaning the Torch
WARNING
WARNING
CAUTION
Even if precautions are taken to use only clean air with a torch,
eventually the inside of the torch becomes coated with residue.
This buildup can affect the pilot arc initiation and the overall cut
quality of the torch.
Disconnect primary power to the system before disassembling
the torch, leads, or power supply.
DO NOT touch any internal torch parts while the AC indicator
light on the front panel of the power supply is lighted.
The inside of the torch should be cleaned with electrical contact
cleaner using a cotton swab or soft wet rag. In severe cases, the
torch can be removed from the leads (see Section 4.7, Servicing
Torch Head Components) and cleaned more thoroughly by
pouring electrical contact cleaner into the torch and blowing it
through with compressed air.
Dry the torch thoroughly before reinstalling.
