I went to Cyberweld and checked out Smith regulators. Could not see any "low pressure" units. Am I missing something? Would a low pressure gauge do the same thing?
I have a "Cobra" (henrob, etc...) that I have used with "normal" regulator with the cutting attachment to bore the center hole for a flange in 1" T1 plate (worked fine) but was definitely suffering from "regulator creep". I have spoken with the local Airgas shop (welding supply shop) they have a set of Victor Dual Diaphragm regulators that will supposedly hold steady at the low pressures required. Defiantly proud of them, but I don't mind paying for quality.
These are the regulators I recently purchase from Cyberweld. They seem to work great and a good price for excellent quality. If you go this direction I would call to make sure you get your questions answered. One thing is the picture does not show the actual Oxy gauge you will receive. The description is correct but the picture shows a higher reading outlet gauge. http://store.cyberweld.com/smoxreliduh1.html http://store.cyberweld.com/smacremeduh1.html
