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, this information is normally used only for heavy-
wall applications.
PROGRAMMABLE VARIABLES:
Level/Segment Parameters -
Level parameters are parameters
that may be changed during the weld
sequence.
Level Position - Level Position is
the location of the electrode at
the end of a particular level. If
Level Time is changed, position
values will be adjusted accord-
ingly.
Primary Amps - Background
Amps. When Pulse Mode is ON,
amperage is pulsed between the
Primary (high) amp setting and
the Background (low) amp set-
ting.
Primary Pulse (Time) - Background Pulse (Time).
The Primary and Background pulse timers indicate the
duration of Primary and Background Amps.
