Assist Gas Recommendations
The machine has provision for three kinds of assist gases. The assist gas inputs are at the rear of the machine. The inputs are labeled OXYGEN, CLEAN CUT, and AIR.
Oxygen is normally used to cut steel and stainless steel.
Nitrogen is used to Clean Cut™ stainless steel and aluminum with an oxide free edge. Shop air can be used to cut aluminum at reduced cost (see page 26).
An evaporator will be needed when using liquid
For usage and pressure requirements, contact Amada America’s Laser Group.

Oxygen Purity
When cutting carbon steel with oxygen, higher purity means higher speed.
“Increasing the oxygen purity from 99.7% to 99.9% resulted in a cutting speed increase in ex- cess of 10%.” according to the BOC article referenced below.
