D. 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 pilot arc initiation and the overall cut quality of the torch.
WARNINGS
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 electrical 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.
E. O-Ring Lubrication
An O-ring on the Torch ATC Male Connector requires lubrication on a regular basis, depending on how frequently the torch
is disconnected and re-connected. This will allow the O-ring to remain pliable and provide a proper seal. The O-ring will dry
out, becoming hard and cracked, if the O-ring lubricant is not used on a regular basis. This can lead to performance problems.
It is recommended to apply a very light film of O-ring lubricant (Catalog # 8-4025) to the O-ring on a weekly basis.
NOTE
DO NOT use other lubricants or grease, they may not be designed to operate within high temperatures or may
contain “unknown elements” that may react with the atmosphere. This reaction can leave contaminants inside the
torch. Either of these conditions can lead to inconsistent performance or poor parts life.
