Welding torch replacement is complete, wearing parts have been installed:
switch on power source
Adjust the stick out according to application
Upload the reference program and slowly approach the reference position on the
adjustment gauge
Thread in wire electrode until this touches the adjustment gauge
Check the position of the wire electrode to the laser focus
Using the robot, move to the reference

point on the gauge (1):
the laser focus is in the cross hair on
the gauge

trode in relation to the laser focus:
The position of the wire electrode
must match the values documented
on the gauge using scaling.
