I am new to TIG so more or less trying to figure out the little things that are needed. I had some classes a long time ago [like 40 years] so that will not be much help. Love the videos on you tube though. I can watch those for hours. Way better than my wifes Dr Phil!! I am looking at Part# AK-4-Pro, from arc zone which is a kit of various torch parts. Is there any compatibility issues with with the wp20f torch? I bought a 125 tank yesterday. I have the personal protection equipment already. Going to get a variety of different tungstens up to 1/8 as well as filler rod. Nearest welder supply is about 20 miles from here and hate to make a ton of trips. Money is not the biggest issue just yet but nearing the end of money I saved from not smoking in 2012.
