CONTACT TIP ALIGNMENT
During gooseneck replacement or after a torch colli-
sion it may be required to check the contact tip align-
ment. If using a robot, it is recommended that a tool
center pointer is placed in the robotic cell to define the
location of the lead wire. A second locating station
should be installed that provides two locating pins that
will check the alignment of the lead and trail wire.
If the torch requires maintenance that will effect the
alignment of the lead or trail wire placement, the torch
should be removed from the robot or hard automation
work cell and the L10430-1 torch alignment tool
should be used to realign wire placement.
