If you chose the Manual Double Pulse function, the
Manual Double Pulse menu, as shown in Fig. 30 will
open.
Fig. 30
In Manual Double Pulse, you can adjust the frequency
from 0.4Hz to 4Hz. DP DutyCycle refers to the (peak)
pulse-on time. The peak settings are the weld settings
displayed when you press the B ( Home ) button. DP
Mot. Perc. refer s to the background wire speed. In
the case of Fig. 30 , where the DP Mot. Perc. is set to
70%, if the peak wire speed is set at 300 IPM, the
background IPM is set to 210 IPM, along with whatever
amperage and voltage that works out to be. Since the Pro
Pulse 300 is a full synergic welding machine, the voltage
is also adjusted to match the background wire speed.
Pro Tip: Generally speaking, lower Double Pulse
frequencies, duty-cycle percentages (i.e., shorter pulse-
on times), and Motor Percentages (i.e., lower
background amperages and voltage due to lower wire
speed) make for a more pronounced and defined bead
appearance and ripples. Lower settings also
dramatically reduce heat input, warpage, and
distortion to base metal!
Very extreme double pulse settings may necessitate an
increase in voltage; in some cases, depending on the
settings and the alloy used, you may need to increase
the voltage by as much as +4.0 Volts. You will know
when you achieve sufficient arc voltage when the
crackling in the background disappears.

The green arrow in Fig. 31 points to the Manual Double
Pulse symbol.
Pro Tip: During hot start, slope down, or final current,
there is no double pulse. If double pulse is desired
during hot start or slope down, please use a remote
control (e.g., sliders on MIG welding guns and
potentiometers on spool or push-pull guns) to achieve
the desired effect manually.

The first line gives the operator the option to turn the
smart water-cooler on and off. The water-cooler is NOT
activated and deactivated with the switch on the front of
the cooler—the switch on the front of the cooler should
always be in the ON position. The welding machine
controls the cooler. The smart water-cooler is an on-
demand system; the fan and the pump of the cooler only
run when necessary. Likewise, the cooler controls the
welding output of the Pro Pulse 300. If the smart water-
cooler detects a problem, the cooler will shut off the
welding output and the wire feed motor. The smart-
cooler function protects your expensive water-cooled
push-pull gun and cooler pumps. The smart water-cooler
plugs into the back of the Pro Pulse 300 ( Fig. 3 , Pos. P ),
and into a separate 220/240 volt, single-phase circuit.
The smart water-cooler is NOT powered by the welding
machine. The snowflake symbol in Fig. 33 indicates that
the smart water-cooler is ON (since you may not hear it
our know otherwise).
