IG‐55(50%Argonand50%NitrogenMixture)
TheIG‐55inertgasmixtureconsistsnominallyof50%argonand50%nitrogen.Themixturespecificationisargon
50±5%nitrogen50±5%.
DetailedbelowarestepsnecessarytofillthePROINERTcontainerwithIG‐55bypressure:
Connecttothevalveoutletandpull25"to27"ofthevacuumtoremoveresidualatmosphereandmoisture.
Fillthecontainerviathevalveinletwithargontothepressureindicatedinthetablebelowforthesystem
pressurerequired.
Topoffthecontainerwithnitrogentothefinalfillpressureperthetablebelow.Ifnecessary,refertothe
pressurevs.temperaturechartforIG‐55inAppendixA.2.

NOTE: Performapreliminaryleakcheckatthecylinderneckwithasoapsolution(SwageLokSnooporits
equivalent)onceithasbeenfilledwithargon.Ifaleakisdetected,discontinuefillingthecylinder.
Verifythecontainerbyensuringthefinalfillpressureisasdetailedaboveat59°F(15°C).Ifrequired,referto
thepressurevs.temperaturechartforIG‐55inAppendixA.2.
Closethevalvebyunscrewingthecentralscrewonthefillingadaptorandremovingthetophalfofthe
adaptor.Thedowelontheinternalpieceofthefillingadaptorshouldmovedownwardduringthisoperation.
ProceedwithremovalofthebottomhalfofthefillingadaptorbyunscrewingthetwoM6capscrews.Remove
thisadaptorfromthevalveandcheckthatthespringwasherhasdroppedlowerthanitsoriginaldepth.
Ventthefillinghoseandcheckthatthereisnoflowfromthevalveoutlet.
Fitthevalvelockoutassembly ontothevalve(Figure4.3.1.‐1)priortoremovingthefillinghose.
Removethefillinghoseandscrewtherecoilcapontothedischargeoutlet.
Removethevalvelockoutassemblyfromthevalveaftertherecoilcaphasbeenfitted.
Proceedtoleakchecking(Section5).
Checkcontainerpressure(Section6).
Oncetestingiscomplete,screwthe
shipping/safetycapontothecylinder.
