Up for your consideration is a Victor Edge 2.0 ESS42-150-540 heavy duty oxygen regulator with CGA-540 connection. I have this regulator listed as used because it has some cosmetic scratching in the paint as seen in the last picture but is new and has never been used. I also have many other cutting and welding torches, tools and equipment listed if you are interested. Please feel free to ask any questions you may have and thanks for looking!
