DAE see more pulse welding on stainless jobs now?

Honestly, I had a leak in a stainless steel pipe joint from poor welds. Tbh, I started using pulse welding after seeing it online. I set the peak current to 150 amps and background to 80, with a pulse rate of 2 Hz. Ngl, it fixed the issue and the welds look way cleaner.

Have you tried tweaking those pulse settings for thinner stainless? I found dropping the background current even lower, like to 50 amps, really helps control heat on thin wall tubing. It's a solid method once you dial it in for the specific job.

In my experience, 50 amps risks poor fusion on thin stainless.

Actually ran into this exact problem last week on some 0.065 wall. Dropping the background that low can leave the weld sitting on top without enough bite, especially if your travel speed is off. You really need to watch the puddle shape and maybe bump the peak time up a touch to compensate. It's a balancing act for sure.
