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.

Typical Bench Feeder Connection:

Control cable is connected from the Power Wave Source output Amphenol receptacle to the input Amphenol receptacle on the back of the Wire Drive.

It is recommended that only genuine Lincoln control cables be used at all times. Lincoln cables are specifi- cally designed for the communication and power needs of the Power Wave Source / Power Feed sys- tem. The use of non-standard cables, especially in lengths greater than 25ft(7.6m), can lead to communi- cation problems (system shutdowns), poor motor acceleration (poor arc starting) and low wire driving force (wire feeding problems).

Lincoln control cables are copper 5 conductor cable in a SO-type rubber jacket. There is one 20 gauge twist- ed pair for network communications. This pair has an impedance of approximately 120 ohms and a propaga- tion delay per foot of less than 2.1 nanoseconds. There are two 12 gauge conductors that are used to supply the 40 VDC to the network. The fifth wire is 18 gauge and is used as an electrode sense lead.
