Plasma / Air Shield
This gas combination gives superior cut speed, minimum dross, minimum amount of surface nitriting and
excellent weldability.
Set plasma gas inlet pressure to 120 psi (8.3 bar)
Set shield gas inlet pressure to 90 psi (6.2 bar)
+ SilverPlus provides increased life to high duty cycle users in most applications. The hafnium wears to approximately two times
the depth of a standard electrode (220021). Arc voltage may need to be increased by 5-10 volts throughout the electrode life
to maintain proper cut height parameters.
If leads are greater than 50 feet, increase TEST pressure 5 psi for every extra 50 feet of torch lead length.
Production cutting above 1 inch (25 mm) not recommended.
