The Power Feed 10M Single Wire Feeder is a modular

wire feeder, consisting of two components - a wire drive and a control box - are available assembled as a bench unit or as a boom system. High speed, high-

ly reliable digital cables connect the components together and to the Power Wave power source.

The Power Feed 10M Single Wire Feeder system has the ability to connect multiple wire feeders to one power source, use the same power source to weld in two different locations (not simultaneously), or load a different electrode on each feeder to eliminate change over time.

The powerful four roll wire drive system sets the indus- try standard for ease of use. Its patented design allows for tool-less change out of wire guides and drive rolls greatly reducing set up time.

The Power Feed 10M Single Wire Feeder is a highly versatile wire feeder with easy to use features that make it easy for the operator to adjust the arc for specific preferences.

The new MSP4 panel clearly displays key welding information. Use the MSP4 panel to quickly adjust weld settings, arc starting parameters, arc end para- meters and set-up variables.

The Power Feed 10M Single Wire Feeder wire feed- er is provided with an infrared red (IR) port. Transferring welding settings from one wire feeder to another is accomplished with a common palm com- puter.

When the Power Feed 10M Single Wire Feeder is coupled to a Power Wave welding power source, the result is a welding system with absolutely supe- rior arc performance.
