COAXIAL WELD CABLES
Coaxial welding cables are specially designed welding
cables for pulse welding. Coaxial weld cables feature
low inductance, allowing fast changes in the weld cur-
rent. Regular cables have a higher inductance which
m a y d i s t o r t t h e p u l s e w a v e s h a p e . I n d u c t a n c e
becomes more severe as the weld cables become
longer.
Coaxial weld cables are recommended for all pulse
welding, especially when the total weld cable length
(electrode cable + work cable) exceeds 50 feet
(7.6m).
A coaxial weld cable is constructed by 8 small leads
wrapped around one large lead. The large inner lead
connects to the electrode stud on the power source
and the electrode connection on the wire feeder. The
small leads combine together to form the work lead,
one end attached to the power source and the other
end to the work piece. (See Coaxial weld Cable below.)
WORK CONNECTION
Connect a work lead of sufficient size between the
proper output stud on the power source and the work.
Be sure the connection to the work makes tight metal
to metal electrical contact. Poor work lead connec-
tions can result in poor welding performance.
