8.2.2 Using the Pneumatic Push Button Release Option
The four thumb screws can be replaced with four miniature pneumatic
cylinders (factory installation only). A push-button valve mounted on the
Head pressurizes all four cylinders which cause all four rollers to
simultaneously move downward and outward, allowing the Head to be
installed or removed.

Keep fingers away from the roller until pushbutton valve
released to avoid injury.
The pneumatic option requires 11 - 12 BAR (250 psi) pressure only
during actuation of the pneumatic cylinders to release or install the Head.
No pressure is required once mounted or removed.
Note
: The pressure can be supplied from an external source. A separate
pressure hose is included in the torch cable umbilical. We recommend,
however, that a special gas regulator be purchased which provides this
pressure from the same gas bottle used for torch purge gas. This
provides a preset pressure at a fitting to which the pneumatic hose is
attached. A secondary pressure regulator/flow meter provide standard
control of torch shielding gas.
American Bottle Threading - Order P/N 34816
For European or other bottle threading, contact the local Harris regulator
distributors to obtain the adaptor which is threaded into the valve body.
8.2.3 Using the Manual Thumb Screws
To install the Head, rotate all four thumb screws (at the top of each
caliper actuator) clockwise (CW) until they stop turning. This will cause
all four rollers to move downward from the under space of the weld Head,
and outward away from the side of the Head.
To mount the Head, place it on the Guide Ring or Track, ensuring that all
four V-rollers are lined up in the V-belt grooves. Holding the Head in
place with one hand, turn the four screws CCW until no further force is felt
on the screw.
Recommendation! Engage one of the rollers on either side of the
Ring/Track first to prevent accidentally allowing the Head to fall.
Attention! When mounted, all four rollers should be fully underneath the
steel strip: if not, repeat the mounting procedure above. (Proper location
of limit pins in the pivoting caliper assembly is necessary. See Section
8.2.4.)
