Argon-Hydrogen Manifold (073109) Required*
This gas combination (Hypertherm recommends a mixture of 35% hydrogen and 65% argon for the plasma gas)
gives good cut speed, but may result in excessive dross. Some surface nitriding and surface oxidation of alloying
elements can occur.
*
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)
Production cutting above 3/8" (10 mm) not recommended
