Cleaning Torch
Evenifprecautionsaretakentouseonlycleanair
withatorch,eventuallytheinsideofthetorchbe-
comes coated with residue. This buildup can affect
thepilotarcinitiationandtheoverallcutqualityof
the torch.
WARNING
Disconnect primary power to the
system before 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.
O-Ring Lubrication
An o-ring on the Torch Head and ATC Male Connec-
tor requires lubrication on a scheduled basis. This
willallowtheo-ringstoremainpliableandprovide
aproperseal.Theo-ringswilldryout,becoming
hard and cracked if the lubricant is not used on a
regular basis. This can lead to potential performance
problems.
Itis recommendedto applya verylight lmof o-
ring lubricant (Catalog # 8-4025) to the o-rings on
a weekly basis.
