Greetings Guys : )
Am a new member of this forum, and to DIY/Maker in general, so please forgive my ignorance.
I have recently purchased a 80W CO2 Laser device. So far I am very impressed with the device, but I have a point of concern. When the item is cutting acrylic sheet (between 3 to 5mm) flashes of fire can be seen on the acrylic surface.
Is this normal, or should I be concerned?
Pictures of a flash attached below, flashes appear irregularly but frequently, each flash lasting less than a second.
Cutting parameters is: 15mm/s at 80% of 80W Laser power.
Material is Acrylic with protection paper not removed.
Distance of laser head is approx 1.5cm from surface (machine uses auto-homing function, so I may be a little off).
Laser head has air assist and water cooling (not sure this is relevant).
Many thanks for any advice offered : )
PS
I have baught a CO2 fire extinguisher just in case.
