5.01 General Maintenance
O-rings on the Torch require lubrication on a regular
basis, depending on how frequently the torch shield
cup is disconnected and re-connected. 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 o-ring lubricant is not used on a regular basis.
This can lead to potential performance problems.
Remove and apply a very light film of o-ring lubricant
(Catalog # 8-4025) to the o-rings on a weekly basis.
NOTE
DO NOT use other lubricants or grease on the torch
o-rings. They may not be designed to operate within
high temperatures or may contain “unknown ele-
ments” 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.
