The actual pressure scale to be used will be determined by the length of the torch
cable, the type of welding torch and welding wire as well as wire-feeding conditions.
After adjustment of the drive roll, press the tensioner roller. Should the wire slip when
exiting the contact tip, readjust.

However:
◆
Take care not to apply excessive pressure which will result in wire being
deformed and coatings being damaged.
◆
Excessive pressure will also result in faster drive-roll wear.
