4.10 Gas Selection
A. Plasma Gases
1. Air Plasma
• Mostoftenusedonferrousorcarbonbasematerialsforgoodqualityatfastercuttingspeeds.
• Airplasmaisnormallyusedwithairshield.
• Onlyclean,dryairisrecommendedforuseasplasmagas.Anyoilormoistureintheairsupplywillsubstantiallyreduce
torch parts life.
• Providessatisfactoryresultsonnonferrousmaterials.
2. Argon/Hydrogen (H35) Plasma
• Recommendedforuseon3/4in(19mm)andthickerstainlesssteel.Recommendedfor1/2inch(12mm)andthicker
nonferrous materials. Ar/H2 is not normally used for thinner nonferrous materials because less expensive gases can
achieve similar cut quality.
• Poorcutqualityonferrousmaterials.
• Providesfastercuttingspeedsandhighcutqualityonthickermaterialstooffsetthehighercost.
• A65%argon/35%hydrogenmixtureshouldbeused.
3. Oxygen (O2) Plasma
• Oxygenisrecommendedforcuttingferrousmaterials.
• Providesfastercuttingspeeds.
• Providesverysmoothnishesandminimizesnitridebuilduponcutsurface(nitridebuildupcancausedifcultiesin
producing high quality welds if not removed).
4. Nitrogen (N2) Plasma
• Providesbettercutqualityonnonferrousmaterialssuchasstainlesssteelandaluminum.
• Canbeusedinplaceofairplasmawithairshield.
• Agoodcleanweldinggradenitrogenshouldbeused.
• Whenusedwithawatermistsecondaryitproducessuperiorcutspeedsandcutqualityonstainlesssteelandalumi-
num.
5. H17 Plasma (17.5% Hydrogen / 32.5% Argon / 50% Nitrogen)
•Recommendedfor1/2inch(12mm)andthickernonferrousmaterials.H17isnotnormallyusedforthinnernonferrous
materials because less expensive gases can achieve similar cut quality.
•AlternativetoH35Plasma.Yieldsslightlyhighercutspeedsandsimilarcutquality.
•WhenusingH17,thegasshouldbesuppliedtothegassupplyportmarked“H35”.
•Poorcutqualityonferrousmaterials.
B. Shield Gases
1. Compressed Air Shield
• Airshieldisnormallyusedwhenoperatingwithairoroxygenplasma.
• Improvescutqualityonsomeferrousmaterials.
• Inexpensive-reducesoperatingcosts.
2. Nitrogen (N2) Shield
• Nitrogenshieldisusedwithnitrogen(N2)orAr/H2(H35)plasma.
• Providessmoothnishesonnonferrousmaterials.
• MayreducesmokewhenusedwithAr/H2plasma.
