6-4. Checking/Replacing Retaining Cup, Tip, And Electrode
! Overtightening will strip threads. Do not overtighten electrode, tip,
and retaining cup during assembly. Do not cross-thread parts causing
stripping. Use care during torch assembly and parts replacement.
! Inspect shield cup, tip, and electrode for wear before cutting or whenever cutting speed has been signifi-
cantly reduced. Do not operate torch without a tip or electrode in place. Be sure to use genuine replacement
parts.
. A good practice is to replace both the tip and electrode at the same time.
