I've been using 3/32 but that shouldn't affect the cleanliness should it? You using red tungsten?

Yup I use red for everything. Even titanium

I use red for everything except alum, I use green on aluminum. 3/32" here as well with a #7 cup (most of the time)

I agree with turbotank on the stainless. I've welded quality stainless and it welds nice, but seems like every time I weld a set of "stainless" headers, it seems to get "ugly" "slaggy" welds (like the ones you posted). I say those in quotes, because there not really ugly or slaggy, just not what a TIG should be IMO.

All of the piping on the manifold looks that way as well and it's sch 30 stainless weld els.

looks like you have the base metal to hot.

I did some spool gun work tonight on a fuel tank and then extended a boom cradle on a boom truck. I am picking up a Honda Ruckus this weekend with a botched "stretched" job. Going to redo all of the welds, add some bracing. Also fabbing a custom fuel tank for it out of an old fire extinguisher.

Use a stainless steel brush and quickly brush the welds after your done welding. That will remove the outer burnt later and bring out the shine. Make sure you use a stainless brush though, if you use a non-stainless one it will suck up the corrosive components and rust eventually.

I'll try it out next time vadim, thanks.
