WELDING POWER SOURCE INTERFACE CONNECTION
The Pipe KAT
®
is supplied with a welding power source interface cable that allows the
unit to remotely control the welding contactor circuit, welding voltage, and communicates the
wire feed speed and actual torch voltage (electrode sense) to the welding power source .
Note: 0-10VDC signals are used to remotely control the welding voltage and
communicate the wire feed speed; ensure that the welding power source is
compatible
before connecting.
The welding power source interface cable assembly is comprised of a 12 circuit
connector that mates to left side of the main control box, see page 17, and color coded labelled
wires that the user terminates with their choice of preferred welding power source. Welding
power sources typically have a circular socket type panel connector or terminal strip that will
allow for remote operation, consult the power source manual for detailed hookup instructions.
Below is an example of a typical connection to a welding power source using the supplied
interface cable assembly.
“WF SPD - ” (black wire): terminate this wire to the welding power source remote wire feed
speed common connection.
“WF SPD + ” (brown wire): terminate this wire to the welding power source remote wire feed
speed 0-10VDC analog signal input connection.
Optional signal used to communicate the wire feed speed to the power source. Not required for
all processes / power sources.
“VOLT - ” (red wire): terminate this wire to the welding power source remote volt control
common connection.
“VOLT + ” (orange wire): terminate this wire to the welding power source remote volt control 0-
10VDC analog signal input connection.
This allows the welding voltage to be adjusted by the GULLCO remote pendant, see page 11
“CONTACTOR ” (blue wire): terminate this wire to welding power source contactor control
circuit.
“CONTACTOR ” (white wire): terminate this wire to welding power source contactor control
circuit.
Used to energize / de-energize the welding power source contactor, and in turn the welding
current, during weld cycles.
