Field of applica-
The RA TTW 4000 adjusting device is used in automated applications together

with the Robacta TTW 4000 TIG robot welding torch. Using the adjusting device,
one or more replacement torch heads can be prepared so that they all display
exactly the same tungsten electrode position. Preparing the replacement torch
heads in advance reduces the length of time it takes to replace them.
