2 For further infor-mation, refer to the following publications:AWS "Operator Manual for Oxy-Fuel GasCutting" American Welding Society, 550 Rd., Miami, FL 33126 ANSI "Safety in Welding and Cutting" AmericanNational Standards Institute, 1430 Broadway, NewYork, NY 10018 compressed Gas Association (CGA), 1235 Jefferson-Davis Highway, Arlington, VA 22202 Safety Bulletin SB-8 -"Use of Oxy-Fuel Gas Weldingand Cutting Apparatus" Pamphlet E-1 -"Standard Connections for RegulatorOutlets" CGA Standard V-1 -" compressed Cylinder Valve Inletand Outlet Connections"DescriptionNote:Each type of regulator is designed and assem-bled for specific gases and for definite inlet and deliv-ery pressure RegulatorsMulti-stage regulators are two regulators in seriesusing a common body.

3 The first stage (high pressure)reduces the inlet pressure approximately 90% and ispreset at the factory. The second stage (low pres-sure) is adjustable to the desired delivery RegulatorA cylinder regulator reduces the cylinder pressure tothe delivery pressure and maintains a constant pres-sure to assure an accurate flow RegulatorA pipeline regulator operates from a source of lowerpressure, usually 200 PSI or less; and normally hasonly one gauge, which indicates the outlet regulators must not be used on or with highpressure gas RegulatorsGaugeless regulators are used where rough use andgauge damage are a problem. The cylinder (inlet) pres-sure is shown by the piston-type indicator.

4 The deliverypressure is set by the adjusting knob and shown by thecalibrations marked on the rotation of the adjusting knob (or key)increases the delivery pressure. Counter-clockwiserotation decreases the delivery regulator inlet connections are designed for thegas to be used in accordance with CGA Standard threaded outlet connections are 9/16"-18 maleCGA Standard 022 ( ) and 023 ( ) (formerlyClass B)2. Fuel gas threads are left CGA Standard V-1 " compressed Gas Cylinder ValveInlet and Outlet Connections"2 CGA Pamphlet E-1 "Standard Connections forRegulator Outlets"Safety Instructions1. Handle cylinder with care. Chain or otherwise secure cylinders to a permanent fixture.

5 Take carewhen moving. To transport cylinders (except whenin cylinder carts), remove regulators and replacewith valve cap. Never use any cylinder in other thanan upright Use "good housekeeping" in work areas. Keepsparks and flame away from your work area before welding or Do not oil or grease equipment. The equipmentdoes not require lubrication. Oil or grease is easilyignited and burns violently with "Crack" cylinder valve before installing valve slightly and then close. This will clearvalve of dust or dirt which may be carried to theregulator and cause damage or accident. Do notdischarge flow of gas at any person or Be sure all connections are tight.

6 Don't force con-nections. Never test for leaks with a flame. Use asoapy water solution to check for Use recommended pressure settings. Improperpressures are wasteful. Extreme pressure build-upin regulators is a warning they need Do not work with damaged or leaking soapy water when checking for leaks. Do notuse frayed or damaged Handle equipment with care. Its continued goodservice and your safety depend upon Harris Products Group Gainesville, GA Keep work area well ventilated. Flammable materi-als burn violently in an oxygen atmosphere. Flamesand glowing materials (tobacco smoking) must When working with acetylene, never use at pres-sures over 15 PSIG (Pounds Per Square InchGauge).

7 11. DO NOT FORCE connectors and threads. The dif-ferences are intentional for the various : SAVE THESE INSTRUCTIONSSet-Up Instructions1. Secure gas cylinder in a vertical position; valve Remove cylinder valve Open cylinder valve momentarily to blow out anydust and dirt. Do not discharge flow of gas at anyperson, flames or flammable Attach regulator to cylinder using proper CGA Properly connect equipment to outlet connection Close off all valves downstream of the Turn the pressure adjusting knob (or key) counter-clockwise until it feels free. The regulator outlet isnow Slowly open the supply valve. When full inlet pres-sure is indicated, open line valve or non-flammablecylinder valve wide.

8 Fuel gas cylinder valves shouldnot be opened more than one turn. Hand wheelsor valve wrenches should be kept on the valve topermit quick emergency Slowly turn the regulator adjusting knob (or key)clockwise to obtain the desired delivery for gas leakage should be made at this a soapy water solution at all connections andcheck for bubbles. Tighten connections as requiredand wipe off the soap Test of RegulatorAn internal leak may be detected as follows:1. Close the regulator by turning the adjusting Close cylinder Drain downstream Harris Products Group Gainesville, GA Stage RegulatorMulti-Stage Regulator24. The low pressure gauge will indicate zero. Thecylinder (high pressure) gauge will read full pres-sure.

9 Any pressure drop will indicate before use, or replace with a properly func-tioning A gauge should read zero when all the pressure isremoved. If it does not, it may be damaged. Locateand correct the cause of the damage and replacethe Close downstream Close supply valve on the cylinder or Bleed off gases oxygen first, then close downstream Turn pressure adjusting key counterclockwise Remove regulator from Instructions1. When not in use, store the regulator in a clean andsafe Inspect and test at least every 6 months after Have only qualified repairmen service, test andclean the The gauge lenses are made of Lexan1.
