Just a heads up. many laser cutting systems use an electronic regulator to control the assist gas. These regulators have a vent, when they go bad, assist gas can build up and if it's O2 all it takes is one spark. Had a flash explosion from this last week, rattled the building. The regulator on this machine was next to a leaky hydraulic unit. I heard it was a pretty nice fireball.

I suggest 2 things-

1. keep an eye on your gas system.

2. relocate or vent the regulator to an area where gas cannot build up.

With enough O2, almost anything burns. If your machine does catch on fire, cut all gasses, air and power to it ASAP!

RE: machine fires

That's why on LVD machines, they have a tube going from the vent to the outside of the machine, where nothing is enclosed. There is also a safety valve at the oxygen connection to the machine for the oxygen circuit that will shut off in case of an emergency. Finally, they have a fire extinguisher with fire trace line; that thing really works, I know from experience. As preventive maintenance, the oxygen circuit should still be checked for leaks once in a while. Oxygen leaks in enclosed areas can indeed be very bad.

I figured you saw some aftermath. I've seen some pretty impressive destruction. I don't wish it on anyone but I embrace and enjoy destruction after cleaning up after it for 30+ yrs :)
