DESCRIPTION AND OPERATION OF CONTROLS - POWER SUPPLY AND PENDANT
1.1
Power Source Description
The Remote Pendent (Figure 1.1) provides controls necessary to develop, save and call up
welding programs. Programming is selectable position or time-based.
Each program can consist of a maximum of 100 levels. Any and all welding parameters may be
changed at each of the 100 levels. Downslope will occur following completion of the final level
time period.
While welding, the operator can immediately override the programmed parameters within preset
limits.

1.2.5
Soft Keys (Four)
Used to select menu items. These items/functions change depending on operation
mode (i.e., setup, programming, operation).
1.2.6
Home Position Switch
Depressing this switch will cause the weld Head to rotate until it reaches a Home
position, at which point rotation will cease. (Home Position for the D-Head/T-Head is
one of 6 locations located 60° apart around the Guide Ring.) Active only when no
arc is present, this switch causes the Head to move forward until one of the position
notches on the guide ring is found. When using Autorewind, the weld Head will
rotate in reverse until finding the Home location.
1.2.7
Start Weld/Start Downslope
Used to start a weld, or to initiate downslope if a weld is in progress.
1.2.8
Emergency Stop Switch
Used to immediately terminate the weld cycle and all weld Head functions.
ATTENTION
:
In nonwelding operation, this switch is used as an “Escape” back
to the Start Up screen/Main Menu.
