Using pulsing to reduce heat input?

I like the 60hertz pulse setting as you have a more fluid puddle (Miller 150STH-It is funny hearing 60hz from a dc unit). I like to dip so I haven't found too many uses for the other pulse rates except for thin stuff. I'd imagine someone could teach/explain to me how to use the lower pulse settings (.5,1.2.5hz) more effectively but I do well with 60hz. Any comments would be welcome if this isn't seen as a thread jacking :)
Look for old posts with Ernie's rules of thumb. They baseline at 1amp per thousandth of an inch.

OK, so, what are your low vs. high pulse widths (relatively) and what are your high and low currents? I can set all these things on my welding machine.
Got it... thanks a lot...

Here are some basic settings to start with
Pulses per Second 1.2 - 2.0 Background Amperage 40% Peak time 40%
Remember that when using a pulser, you will set your machine slightly higher, since you are not maintaining a constant arc.
The pulse frequency or 1.2 - 2 pps allows you to add filler on every pulse. You can go to a higher pulse frequency and simply add filler every second or third pulse.
Running in the very high frequencies on the pulse makes for a more liquid weld, especially on SS and aluminum.
The pulser should work just as well on AC as it does on DC.
Obviously you have a huge range of settings to play with.
Have fun, do many test welds and take notes on settings that worked particularly well on certain combinations of material and assembly.
For more settings for the pulser you can go to this site.
and this site
The range of settings can be a bit bewildering but you have to find out what works for you. "Pax Americana is a philosophy. Hardly an empire. Making sure other people play nice and dont kill each other (and us) off in job lots is hardly empire building, particularly when you give them self determination under "play nice" rules.
Think of it as having your older brother knock the shit out of you for torturing the cat." Gunner

yes, that was helpful.
