5.02 Maintenance - Torch O-Rings
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 elements” that may react with the atmosphere.
This reaction can leave contaminants inside the torch. Either of these conditions can lead to inconsis-
tent performance or poor parts life.
