NOTE
Refer to Previous "Section 5 System" for com-
mon and fault indicator descriptions.
Cleaning Torch
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 arc
initiation and the overall cut quality of the torch.
WARNING
Disconnect primary power to the system be-
fore disassembling the torch or torch leads.
DO NOT touch any internal torch parts while
the AC indicator light of the Power Supply is
ON.
The inside of the torch should be cleaned with electri-
cal contact cleaner using a cotton swab or soft wet
rag. In severe cases, the torch can be removed from
the leads and cleaned more thoroughly by pouring
electrical contact cleaner into the torch and blowing
it through with compressed air.
CAUTION
Dry the torch thoroughly before reinstalling..
