CABLE CONNECTIONS

CONTROL CABLE CONNECTIONS

•All system control cables are the same.

•All control cables can be connected end to end to extend their length.

•All system equipment must be connected to a con- trol cable.

Welding systems using the Power Feed 11 offer previ- ously unprecedented flexibility in the connection of system components. This system uses the same type of control cable between each of the system compo- nents. Connections can be “daisy chained” from one system component to another. Since communication over the control cables is done by a robust communi- cations network, the order of connection of the com- ponents makes no difference. The cables can be con- nected anywhere that there is a mating connector.

CONTROL CABLE SPECIFICATIONS

The cable is a 5 copper conductor cable in a SO-type rubber jacket. There is one 20 gauge twisted pair for network communications. This pair has an impedance of approximately 120 ohms and a propagation delay per foot of < 2.1 ns. There are two 12 gauge conduc- tors that are used to supply the 40 VDC to the net- work. The fifth wire is 18 gauge and is used as an electrode sense lead. It is typically connected to the feed plate on the feed head when that feed head is active.

NOTE: Maximum cable length between any two nodes is 250'.

TYPICAL CABINET FEEDER CONNECTION

The Control cable is connected from the Power Source to the Wire Feeder. The Power Feed 11 comes standard with an 8 ft. Control Cable.

CONTROL CABLE INSTALLATION:

1.Connect the end of the control cable with the 5-pin cable plug to the mating receptacle on the power source. With the pins and key aligned, plug it into the power source, rotate the threaded locking ring until the connector is completely fastened

2.Connect the end of control cable with the 5-socket end to the mating receptacle on the back of the wire feeder. To connect the cable to the feeder,

aligning the pins and key, plug it into the back of the wire feeder head, rotate the threaded locking ring until the connector is completely fastened

Note: Depending on the location of the of the Wire Feeder relative to the Power Source a longer Control Cable or additional Control Cable(s) may be required.See section 2.0 “Optional Features” for information on optional Control Cables.

ELECTRODE CABLE CONNECTIONS

Most welding applications run with the electrode being positive (+). For those applications, connect the elec- trode cable between the wire feeder and the positive

(+)output stud on the power source (located beneath the spring loaded output cover near the bottom of the case front).

A work lead must be run from the negative (-) power source output stud to the work piece. The work piece connection must be firm and secure, especially if pulse welding is planned. Excessive voltage drops at the work piece connection often result in unsatisfacto- ry pulse welding performance.

When negative electrode polarity is required, such as in some Innershield™ applications, install as above, except reverse the output connections at the power source (electrode cable to the negative (-) stud, and work cable to the positive (+) stud).

ELECTRODE CABLE INSTALLATION:

The Power Feed 11 comes with an installed electrode cable. Connect the power source end of the cable to the power source output terminal of the desired polari- ty.

The K1636-1 Power Feed 11 (Europe) electrode cable is equipped with a Twist-Mate™connector while the K1635-1 Power Feed 11 (World) is equipped with a lug connector. Also for both models open the Wire Drive compartment door and check that the electrode cable lug is against the Feedplate and that the con- nection is tight. Any electrode cable replacement or extension should be sized according to the specifica- tions given in the work cable connections section .
