Reply:I find the chart from welding city to be very useful to newbs such as myself that also just got a wp9 as well with some large nozzle accessorieshttp://www.weldingcity.com/tig_parts_selection.JPG
Reply:Tig experts, what is the advantage of a "gas lens" over a standard ceramic cup? I am only running an older miller econotig, ang do well with a 3/32" or less tungsten and a 3/8 cup.  Most of my welding is under 1/8" fishing boat repairs, I have spool guns for the thicker stuff.
