Hey Yall!

Ive really been putting my Dynasty 200dx to the test and pushing all sorts of buttons. One feature Ive really taken a liking to is the auto pulse on high speed settings.

I usually run
150 main
60% peak
40% Background
200 PPS

These setting work amazing for me on Sch10 and 40 stainless and for 1/2 flanges I just kick up the main to 200 amps with great results. The overall heat input is greatly reduced and directional control and penetration is increased. I also have been saving quite a bit of gas because I'm able to set my post flow to just 7 seconds and keep great coverage with a large lens and #12 cup.

The welders I used to work with were very against high speed pulsing, they considered it "cheating". One of them did some welds using is and loved it, he didnt even know though with headphones in, haha.

I would like to know who else uses it and what settings you like. I personally won't go back to non pulsing. Heres some articles for you guys not in the know

when i am fusing thin stainless sheet use 1000 pps. & around 500 pps on real thin al sheet when adding 5356.

 

I have only used higher speed pulsing for tacking thin material. It seems to draw the material together better i have found. I normally only pulse on thin material as it helps reduce heat input substantially, While still allowing full penetration.

I haven't welded sch10/40 in a few months but i don't know how much i would liek pulsing at those high amperage's. I would feel less in control unless you spent a long time dialing in the settings.

 

not sure that i have ever used pulse on any pipe.

 

Great information here and all over that Miller site!

 

Wow, My machine nly goes to 500 PPS and I haven't even tried to mess with it on AL. What are the differences you find on AL??


I love it for tacking as well! And at first I didn't like the high speed pulsing but after going through about 5 bottles of Argon determined to get it right I settled on those settings and they feel very similar to say a syncrowave 200 but better.

 

The information on that Miller page really didn't seem to indicate any benefits from going over 200-250pps, did they?
