I do not post much but I sure read allot. Thought I would post my first attempt at autogenous stainless tube. I would like to get proficient enough to build a set of headers for my small block 400 and possibly pipes for my old Honda. The first weld was on the left and ofcourse the second on the right. I cleaned part of the second and left the colors on the remainder for reference. 304 ss .065 wall, Diamond Ground TriMix 1/16, #5 cup, 15 Argon, transformer machine at 75 amps, pedal and I set the pulse on the second weld at 10. It seemed to flow a little better. I did use filler for the first weld but only on a short stitch. I guess I need to cut this puppy open to see where I am at. I'll connect a purge soon,. Any comments???
I see I missed a spot on the 2nd weld, will have to watch the closer.
