If you have a known infection, pulse 50 times or so in the same spot. Example. I had a pimple that would just about heal and then come back again over and over on my arm. I pulsed 50 times and it is now gone for good. I earlier would just pulse 2 times or so.
I think the recommended amount of pulses is 20. When pulsing the Lymph or other areas where I can't tell if the area is infected or not, I pulse about 5 time.
