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.
Set plasma gas inlet pressure to 120 psi (8.3 bar)
Set shield gas inlet pressure to 90 psi (6.2 bar)
Note: Maximum piercing thickness 3/4" (20 mm) and IHS recommended.
If leads are greater than 50 feet, increase TEST pressure 5 psi for every extra 50 feet of torch lead length.
* Production cutting above 7/8 inch (21 mm) not recommended.
WARNING
Do not use water muffler when
cutting with argon-hydrogen!
