Victor TurboTorch 0386-0814 245-03P Regulator Nitrogen Certified features nitrogen purging: When brazing copper, it is imperative to purge with nitrogen in order to minimize or eliminate oxidation that results from heating the copper pipe. Without purging, oxidation will occur and the oxidized flakes that result can and will break off and flow through the system, damaging bearings and fouling system filters. All that is needed is a low pressure, low volume flow of nitrogen. The use of dry nitrogen gas also minimizes the need to evacuate moisture from the system. The process for this regulator is Oxy-Acetylene Components and is for use on high capacity and HVAC applications. The range for the gauges is 600 to 4,000 PSIG and the delivery range is from 0-500 PSIG.
