COAXIAL WELD CABLES
Coaxial welding cables are specially designed welding
cables for pulse welding or STT welding. Coaxial weld
cables feature low inductance, allowing fast changes
in the weld current. Regular cables have a higher
inductance which may distort the pulse or STT wave
shape. Inductance becomes more severe as the weld
cables become longer.
Coaxial weld cables are recommended for all pulse
and STT 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.)
WELD CABLE 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.
