NON-SYNERGIC WELDING MODES

A Non-synergicwelding mode requires all welding process variables to be set by the operator.

SYNERGIC WELDING MODES

A Synergic welding mode offers the simplicity of sin- gle knob control. The machine will select the correct voltage and amperage based on the wire feed speed (WFS) set by the operator.

General Physical Description

The POWER FEED® 25M is a premium portable wire feeder for use with the Power Wave products. The wire feeder features a 2 roll MAXtrac™ drive coupled to a powerful motor for driving wire through difficult situa- tions. The easy-to-use, MSP4 interface provides ready access to all welding modes in the Power Wave. A six button memory panel is included with the POWER FEED® 25M and allows quick recall of favorite weld procedures. All the components are packaged in an engineered aluminum case protected by replaceable skids.

The heart of the POWER FEED® 25M is the MAXtrac™ drive. The patented features on the wire drive offer tool-less changing of the drive rolls and the wire guides for quick spool changes. Plus, the drive can be configured for extra torque when feeding large diameter flux cored electrodes.

The POWER FEED® 25M continues Lincoln’s lead role of environmental protection for electronics. P.C. boards are potted in epoxy and electrical connections are protected with dielectric grease. Noise suppres- sion components protect the POWER FEED® 25M from stray signals and keep the feeder from interfering with other digital equipment.

General Functional Description

The POWER FEED® 25M is best suited for applica- tions were quality welds are expected. Combined with a Power Wave power source, the POWER FEED® 25M is great for aluminum, nickel, alloy and other difficult to weld materials. Easy to use controls make it a great feeder for consistent results with mild steel applications too.

DUTY CYCLE

The POWER FEED® 25M is rated for 500 amps, 60% duty cycle and 400 amps, 100% duty cycle. The duty cycle is based on a 10 minute cycle.

For example, when welding at 500 amps, the POWER FEED® 25M may run 6 minutes and must idle for 4 minutes.
