Feature:1. Wide Application: This argon regulator has a G5 8 14 fitting so it can be screwed directly into Argon, Argon CO2Tanks. ideal for MIG TIG welding, chemical and electronic industries.2. Accurate Counting: This gas regulator reads from 0 to 25, indicated by a ball that moves up and down in the flow tube. And has a large 1 1/2inch diameter pressure gauge that reads from 0 to 4000 PSI . Easy to read and accurate.3. Long Life: The body of this argon gas flow meter regulator is made of reliable brass and is robust enough to withstand harsh environments and has a long life span.4. Ideal for CGA 580 Tank Accessory:This gas pressure regulator can be used with argon, argon CO2 tanks (CGA 580 inlet) so it will screw directly into argon, argon CO2 tanks.5. Single Stage Piston Design: This gas pressure regulator features an economical flow meter regulator and a single stage piston design that combines the regulator and flow meter into one compact and lightweight unit that is easy to use. The argon gas regulator is ideal for professional TIG MIG welding applications to reduce and control pressure levels. And the ergonomic flow meter can be adjusted for different applications.Specification:Item Type: Argon Pressure RegulatorMaterial: Brass ABSModel: WX 191 03Application: This gas pressure regulator can be used with argon, argon and CO2 gas tanks (CGA 580 inlet).
