The TRAVEL DIRECTION SWITCH determines the direction of rotation of the
weld Head when welding is initiated. It should be noted that there is no
conventional "forward" direction for the Pipeliner. This switch allows bi-
directional welding - for example the use of double down or double up welding
techniques where travel direction is changed twice per pass.

TORCH AND CABLE
The water-cooled torch is rated at 300 amperes at 100% duty cycle. The torch
body is designed to accept standard Binzel torch components. All torch services
as well as the control cable for the welding Head functions are contained within
the umbilical.
7.5 GUIDE
RING/FLX-TRACK
The Guide Ring serves to mount the weld Head on the pipe being welded and
forms an integral part of the propulsion system. Rotation of the weld Head
around the pipe is accomplished by a friction drive system, consisting of the
powered V-rollers driving against the two V-belts which are attached to the guide
ring surface (U.S. Patent No.)
Guide Rings consist of two identical half sections which quickly bolt together.
Guide Rings are available for all standard pipe sizes 6" (168mm) and larger.
It is possible to use a Guide Ring on pipe smaller than the size for which it is
designed. For example, using stand-off adaptors, a 12" (324mm) Guide Ring
can be practically used on pipe as small as 8" (219mm).
Flx-Track allows the Head to be mounted on either flat or curved surfaces using
various mounting systems.
ATTENTION!
Flx-track is designed to be used within the following limits:
•
When using magnets for mounting, ensure that magnets are clean of
metal debris before using and have maximum contact with the surface.
Be aware that magnets will permanently lose holding force if heated. A
safety cable is required to prevent unexpected release of the Flx-Track.
•
When using vacuum cups for mounting, periodically clean the cups to
ensure a tight seal against the surfaces.
