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 connections can result in poor welding
performance.
