Level Advance: For all autogenous tube and pipe welds
select Auto mode. Auto, Manual and External Level
Advance are available from the pull-down menu.
Stubout Mode - Stubout Mode is typically turned ON for
autogenous orbital welding. It must be OFF when using the
manual torch.
Pulse Mode - Select ON for all autogenous welding.
Travel Mode - Use the Pull-down
menu to select Travel Mode. Cont
is typically used for autogenous
tube welding.
Travel Start Delay - Electrode Travel Start (Rotation)
Delay. This must be long enough to achieve full penetration
before beginning rotation. Typically 1 to 2 sec.
Travel Direction - The default Travel Direction for Arc
Machines’ weld heads is clockwise (CW). Other choices on
the pull-down menu are Counterclockwise (CCW) or travel
OFF. Select OFF for use with manual torches.
Start Position - The Start Position documents the start
location of the electrode (when the tube is in the horizontal
5G position). The default position is 3 O’clock. Selection of
a different start location requires the operator to position
the weld head accordingly. Since most thin-wall tube weld-
ing applications are not significantly affected by the Start
Position, the default Start Position is normally used.
