POWER WAVE / POWER FEED WIRE FEEDER INTERCONNECTIONS

Connect the control cable between the power source and wire feeder. The wire feeder connection on the robotic Power Waves is located under the spring loaded output cover, near the bottom of the case front. The control cable is keyed and polarized to prevent improper connection.

For convenience sake, the electrode and control cables can be routed behind the left or right strain reliefs (under the spring loaded output cover), and along the channels formed into the base of the Power Wave, out the back of the channels, and then to the wire feeder.

Output connections on some Power Waves are made via 1/2-13 threaded output studs located beneath the spring loaded output cover at the bottom of the case front. On machines which carry the CE mark, output connections are made via Twist-Mate receptacles, that are also located beneath the spring loaded output cover at the bottom of the case front.

A work lead must be run from the negative (-) power source output connection to the work piece. The work piece connection must be firm and secure, especially if pulse welding is planned.

CAUTION

Excessive voltage drops at the work piece con- nection often result in unsatisfactory pulse weld- ing performance.

CONTROL CABLE SPECIFICATIONS

It is recommended that genuine Lincoln control cables be used at all times. Lincoln cables are specifically designed for the communication and power needs of the Power Wave / Power Feed system.

CAUTION

The use of non-standard cables, especially in lengths greater than 25 feet, can lead to communi- cation problems (system shutdowns), poor motor acceleration (poor arc starting) and low wire dri- ving force (wire feeding problems).

------------------------------------------------------------------------

Lincoln control cables are copper 22 conductor cable in a SO-type rubber jacket.

EXTERNAL I/O CONNECTOR

The Power Wave is equipped with a port for making simple input signal connections. The port is divided into three groups: Trigger group, Cold Inch Group and Shutdown Group. Because the Power Wave is a ‘slave’ on the DeviceNet network, the Trigger and Cold Inch Groups are disabled when the DeviceNet/Gateway is active.

The shutdown group is always enabled. Shutdown 2 is used for signaling low flow in the water cooler. Unused shutdowns must be jumpered. Machines from the factory come with the shutdowns already jumpered. (See Figure A.3)
