Set plasma gas inlet pressure to 120 psi (8.3 bar)
Set shield gas inlet pressure to 90 psi (6.2 bar)
If leads are greater than 50 feet, increase TEST pressure 5 psi for every extra 50 feet of torch lead length.

Shield
This gas combination (Hypertherm recommends a mixture of 35% hydrogen and 65% argon for the plasma
gas) gives maximum thickness cutting capability, excellent cut quality and excellent weldability. Electrode
life is extended when this combination is used.
WARNING
Do not use water muffler when
cutting with argon-hydrogen!
