PIPEFAB™ WELDING SYSTEM INSTALLATION
CONNECTION BETWEEN POWER SOURCE AND ETHERNET NETWORKS
The PipeFab™ is equipped with a ODVA compliant RJ-45 Ethernet connector, which is located on the
front panel. It is cri�cal that all Ethernet cables external to either a conduit or an enclosure are solid
conductor, shielded cat 5e cable, with a drain. The drain should be grounded at the source of
transmission. For best results, route Ethernet cables away from weld cables, wire drive control cables,
or any other current carrying device that can create a fluctua�ng magne�c field. For addi�onal
guidelines refer to ISO/IEC 11801. Failure to follow these recommenda�ons can result in an Ethernet
connec�on failure during welding.
USB PORTS
When equipped with the Op�onal Connec�vity module K4720-1; the PipeFab™ will be able to connect
remotely (wireless) via a USB WIFI adapter (customer must supply) or wired through an Ethernet cable.
WELD CABLES, COAXIAL
FIGURE A.35
Coaxial welding cables are specially designed welding cables for STT™ and pulse welding. Coaxial weld
cables feature low inductance, allowing fast changes in the weld current. Regular cables have a higher
inductance which may distort the STT™ waveshape. 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 mul�ple small leads wrapped around one large lead. The large
inner lead connects to the electrode stud on the power source and the electrode connec�on on the wire
feeder. The small leads combine together to form the work lead, one end a�ached to the power source
and the other end to the work piece.
