6. Reinstall the Electrode by pushing it straight into
the torch head until it clicks.
WARNINGS
Refer to the consumables selection charts for the
proper combination of torch parts, including
shield cups and shield caps.
The use of any consumable parts other than
those specified by the Manufacturer may cause
irreparable damage to the torch head.
7. Reinstall the desired starter cartridge and tip into the
torch head.
8. Hand tighten the shield cup until it is seated on the torch
head. If resistance is felt when installing the cup, check
the threads before proceeding.
NOTE
When operating the torch in a normal condi-
tion, a small amount of gas vents through the
gap between the shield cup and the torch
handle. Do not attempt to overtighten the shield
cup as irreparable damage to internal compo-
nents may result.
B. O-Ring Lubrication
This section applies only to torches withATC connec-
tors.
An o-ring on the Torch ATC Male Connector requires
lubrication on a regular basis, depending on how fre-
quently 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 potential 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 tem-
peratures or may contain “unknown elements”
that may react with the atmosphere. This reac-
tion can leave contaminants inside the torch.
Either of these conditions can lead to inconsis-
tent performance or poor parts life.
