Coaxial weld Cable
(See Table A.2)
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 cables work best for high performance waveforms and
when:
• long cables are present.
• the cables are housed in a metal tray.
A coaxial weld cable is constructed with multiple 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 Figure A.5
To install:
1. Turn the input power off at the welding power source.
2. Connect one end of the center lead to the power source electrode
connection, and the other end to the wire feeder electrode
connection.
3. Connect the outer lead bundle to the power source work
connection, and the other end to the work piece. Minimize the
length of any work lead extension for best results.
4. Insulate all connections.
