7.0 GAS CHAMBERS
The Model 96 features a cylindrical gas chamber to surround the
weld, providing excellent gas coverage. The weld head comes with
an opaque chamber. A clear glass chamber that can aid in weld
schedule development (as it allows the operator to see the weld puddle
being formed), is available as an optional accessory.
7.1
To remove the chamber, first release the two side latches, and
remove the nose ring. Grip the chamber and twist it while pulling it
away from the weld head.
7.2 Install the gas chamber by pressing it onto the O-ring in the
housing. Be sure it is fully seated. Applying a very thin film
of light oil or O-ring lube to the top of the chamber (on the I.D.) or to
the O-ring will make installation and removal easier.
