Height Sensitivity
Height sensitivity is a global setting available regard-
less of the weld mode selected. The operator can
program the system to react to changes following the
profile of the joint.
Higher sensitivity will result in faster adjustment which
could cause hesitation in torch height and abrupt
changes in the weld as shown in
FIGURES A and B
.
Maintaining a low height sensitivity allows for higher
quality and more consistent welds. This includes ad-
justing for out-of-round pipes, maintaining heat input
and helping with puddle control on the joint profile.
It is recommended that the operator start the weld at a
lower sensitivity setting for the best performance. This
will also assist in avoiding an over reaction to changes
in the structure of the materials being welded.
