Back purging is a must when welding Stainless steel and Titanium otherwise you are left with a brittle, oxidized weld on the inside of the pipe which will fail and hinder flow. You want the weld to look and perform the same on the inside as to the outside. Our Purge Cups are designed for ease of use. Simply tighten the set screw down to the pipe. Hold it to a vice. Back purge and weld away!
