GENERAL DESCRIPTION

The POWER FEED® 25 Single Wire Feeder is a 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, highly reliable digital cables connect the components togeth- er and to the Power Wave power source.

The POWER FEED® 25M Wire Feeder system has the ability to connect to one power source, use the same power source.

The powerful two 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.

GENERAL FUNCTIONAL

DESCRIPTION

•The POWER FEED® 25M 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® 25M Wire Feeder is provided with an infrared red (IR) port. Transferring welding settings is accomplished with a common palm com- puter.

•When the POWER FEED® 25M Wire Feeder is cou- pled to a Power Wave welding power source, the result is a welding system with absolutely superior arc performance.
