air assist cone

Just a little cautionary tale!

Recently,despite regular reminders, one of our students used our VL300 without switching on the extraction cart, resulting in a badly burnt lens. I ordered and fitted a new one without any problem, but after a short time the machine stopped cutting. I looked at the lens and found that this too had been ruined! The reason was that I had not spotted that the small hose connecting the air supply to the air assist cone had melted during the first incident & blocked the air supply to the cone. Result, one brand new lens destroyed and £250+ down the drain!

I guess the moral is after an overheat, check everything that might be affected, not just the obvious stuff.

Thanks for sharing!
Also remember to never leave a Laser un-attended when it's cutting.

Quite true! Could you by any chance supply a replacement tube (just the tube, the needle valve & fittings are fine)?

The laser air assist tubing is just a piece of 4mm OD nylon tubing
