Connecting the Assist Gas
Connect the appropriate assist gas to the machine. The laser system requires nitrogen (N
2
) or compressed air
to cut stainless steel, aluminum, copper and brass, and requires oxygen (O
2
) to cut mild steel.
IMPORTANT
If compressed air is used as the assist gas, make sure it is WATER FREE AND OIL FREE. Otherwise, the
protective lens in the laser head will get dirty and wet, and will be broken by the laser while cutting.
