Overtightening will strip threads. Do
not overtighten retaining cup during
assembly. Do not cross-thread parts
causing stripping. Use care during
torch assembly and
replacement.
!
Inspect shield cup, tip, and electrode
for wear before cutting or whenever
cutting speed has been significantly
reduced. Do not operate torch with-
out 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.
