3 SERIES TIG PENDANT MANUAL
Track Setup
The Track setup screen presents the user with several
options. From this screen the operator can change
the type of track, the size of the track and the size of
the pipe.
Track Type
The first selectable option is track type. With the track
type field highlighted in red, the user is able to switch
between the different types of tracks. These tracks
consist of:
•
Outside Diameter (OD) Track
•
Inside Diameter (ID) Track
•
Flat Track
With both the Outside and Inside Track options, the
user is required to enter the track ring size and the pipe
size. The correct numbers need to be input for calibra-
tion of the travel speed.
Track Ring Size
Track sizes range from 4 to 100 inches in increments of
2 inches. Pressing and holding the right toggle will in-
crease the speed at which the values change. Use the
nominal sizes for the track rings. THESE NOMINAL
SIZES ARE STAMPED INTO THE TRACK.
Pipe Size
The third field that can be changed is the pipe size. This
can range from 4 inches to 100 inches. The value can
be adjusted in increments of 0.01 inches. Holding the
right toggle for longer than 2 seconds will amplify the
speed at which the values increase.
Heavy Wall Pipes
Heavy wall pipes may require the user to change the
pipe size in later passes.
Example: A 20 inch Schedule 120 pipe has an OD of
20 inches and an ID of 17 inches. The pipe diameter
for the root pass should be entered as 17.00 inches,
then increased as the weld progresses outward. This
will help to maintain an accurate welding travel speed
throughout the weld.
Note: To see additional OD and ID pipe and tube size
information, please refer to the "Standard Schedule
Pipe and Tube Chart" on page G-54.
