Argon-Hydrogen Manifold (073109) Required*
This gas combination (Hypertherm recommends a mixture of 35% hydrogen and 65% argon for the plasma gas)
gives maximum thickness cutting capability, minimum dross levels, minimum amount of surface contamination,
excellent weldability and excellent cut quality on thicknesses greater than 1/2". On thicknesses less than 1/2",
excessive dross levels may be experienced. Electrode life is extended when this combination is used.
* See Section 7 for installation and operation with Argon-Hydrogen Manifold.
Notes:
Set argon-hydrogen plasma gas inlet pressure to 120 psi (8.3 bar)
Set nitrogen shield gas inlet pressure to 90 psi (6.2 bar)
Drop cutting above 1-1/2" (38 mm) not recommended.
Production cutting above 7/8" (22 mm) not recommended
Above Water Only
WARNING
Do not use water muffler
when cutting with argon-hydrogen
