ALUMINUM SYNERGIC GMAW-P (PULSED MIG)AND GMAW-PP (PULSE ON PULSE) WELDING

The Power Feed™ 10M Single Wire Feeder and Power Wave welding power source combine to readily produce top quality aluminum welds with excellent appearance, little spatter 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 Wave 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" appearance, similar to GTAW welds.

FIGURE B.7c

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.

FIGURE B.7d

Frequency Modulation = -10 Wide weld and ripple spacing, slow travel speed.

FIGURE B.7e

Frequency Modulation = 10 Narrow weld and ripple spacing, fast travel speed.
