I had to dig through the online PDF manual to find the pulser options.
"Pulse Frequency: Choose from the following four intervals:
.5 PPS, 1 PPS, 2.5 PPS, or 60 PPS".
The most useful pulse frequencies in that list will be 1 and 2.5 PPS.
With these frequencies you can add metal on every pulse or every other
pulse.
60 PPS is used for autogenous welds, where no filler rod is added.
The high frequency of the pulse will super-liquify the weld pool and
make a smooth weld bead.
