WARNING
Refer to the consumables se-
lection charts for the proper
combination of torch parts,
including shield cups and
shield caps.
The use of any consumable
parts other than those speci-
fied by the Manufacturer may
cause irreparable darnage to
the torch head.
7. Reinstall the desired starter cartridge and tip into the
torch head.
8. I-land 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 condition, 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 darn-
age to intemal components
may result.
8. 0-Ring Lubrication
This section applies only to torches withATC con-
nectors.
An o-ring on the Torch ATC Male Connector requires
lubrication on a regular basis, depending on how fre-
quently the torch is disconnectcd and re-connected.
This will allow the o-ring to remain pliable and pro-
vide a proper seal. The o-ring will dry out, bccoming
hard and cracked, if the o-ring lubricant is not used
on a regular basis. This can lead to potential perfor-
mance 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.
