I was just curious , what size tungsten are you guys using when welding the manifolds together. Ive been using a 3/32 2% lanthanated. I used to use the thoriated red but switched iver. Id like to get the welds narrower, dropping down to 1/16 would help with this yes?

I found going to a smaller diamerter filler rod made welds narrower. Like using mig wire vs 1/16 filler rod.

Also 1/16 tungsten helps with control as well, bit if the point is ground similarly to the 3/32, then there won't be as much difference. (From what I could tell)
 
I just want to improve aesthetics, im gunna bevel my bends even more, the 90 bends come beveled but i think theres room for improvement. I just want the welds to lay flatter and stay thinner
 
What filler size are you using? Idealy you want to run either .030 or .045. 3/32 sharpen to a narrow point works fine. Also a quick autogenous weld first helps around bolt holes. It will give you a narrower bead as you will be using less amps, so the cone will be smaller. This will leave a bit of under cut that you can easily back filled with a small gauge filler. Or you can try and single pass it with an .030" wire.
 
Just need a deeper bevel
Thats what I was thinking , i dont bevel the 90s that come beveled just the pipe that I cut. Do you bevel the 90s that come beveled? As for wire I use 3/32 or 1/16. I tend to use thinner filler wire and keep the amps around 90 when welding the pipe . For the head flange I go to 120 amps and dial it in from there once it gets hot
