Got my new pt185 and want to weld my first manifold. What are the proper setting to get this welded? 304ss sch.40

 

umm, anyone?

 

I would go with a 3/32" 2% thor tung., 1/16th" 308 filler, about 125-140 amps, and maybe 15-18 cfh argon. Remeber to bevel the edges for better penetration. You may even want to purge the inside of the tubing since it is SS. Here is a handy little Calculator from Lincolns site that will help you with your settings:

Sched 40 is a little thicker then 1/8"
