I just took delivery of my chinese 1390 laser with a metal cutting head. The back of the laser has a port for the air assist and i see where there connects to the head. That port is near the tip but there are two other ports, higher up on the head. Nothing is connected to these.

In looking at pictures online, i've seen all ports being used in series where one connects to the next. But I've also see where oxygen is just connected to the rear port.

Should I be using the other two ports? What's the best way to hook up the air assist and oxygen?

Thanks so much guys.
