WIRE FEED SHUT DOWN CIRCUIT |
| |
The wire feed shut down circuit is used to stop the wire feed in the event of a fault. The most common use of the circuit is with water cooled guns. A flow sensor is connected to the circuit to protect the welding gun if the water flow is interrupted.
The Power Feed 10M Single Wire Feeder has two leads, 570A and 570B, located inside the wire drive that are electrically common. If flow switch is used, separate these leads and connect to normally closed flow switch terminals when water is flowing. Connect the flow sensor to these two leads.

The Power Feed 10M Single Wire Feeder wire drive may be configured for either low speed or high speed, depending upon the application. The wire feeders are factory assembled for low speed operation and include a gear for high speed operation.
