Worm holes and chicken tracks -- Most mfg of E-71-t1 (FCAW-.045) have told us its a result of hydrogen, with suggestions anywhere from oven's, voltage settings, change arc distance, verify removal all cutting slag, verify paint has been removed on new pipe. All good essential varibles. Our best solution is changing from 75-25 to 100% CO2 gas. Most of our weldments are multi-pass flat to near flat-- E-70 T1 ULTRA unless the need fast freeze required for small pipe rollouts we return to the E-71.
Have yet to find a E-71 mfg that doesn't have this issue with this wire.
If you know one I'm interested.

So this thread is why I hang out here on this forum--AMAZING!

I have to go over and reread some of the information but these posts are addressing questions I have had the Pulse/Spray/MIG monstrosity that I am trying to figure out. I have been on weldreality but havnt gotten through it yet. I am planning on studying this thread, then reading Craig's site, then posting my much more educated questions/problems with the machine. Thanks to all of you for all the time put into answering these questions so thoroughly.

Also, Stephen, I forwarded the posts about the Higg's Boson one page explanations to a math/physics teacher I know. I enjoyed reading them. Welding is my job and math is a hobby so I appreciate being able to read about both at the same time!

Best
