The POWER FEED® 25M and Power Wave welding power source combine to readily produce top quality aluminum welds with excellent appearance, little spat- ter and good bead shape. Push-pull guns are available for consistent feeding when welding a long distance away from the wire feeder.

Pulse-on-Pulse Welding

The POWER FEED® system offers both traditional pulse and Pulse-on-Pulse™. Pulse-on-Pulse (GMAW-

PP)is an exclusive waveform for aluminum welding. Use it to make welds with a "stacked dime" appear- ance, similar to GTAW welds.

The pulsing frequency is adjustable. Changing the fre- quency modulation (or arc control) of the waveform changes the ripple spacing. Faster travel speeds may be achieved by using higher values of frequency mod- ulation.
