littlestworkshop: @baccus61 My 50W laser is actually putting out around 80W so it may be the same for your 100W? What is the cut quality like when cutting 0.6mm?

Wilfred Tak: at my work we use nitrogen for (stainless) steel...for nicer cuts (Trumpf Lasers)

littlestworkshop: @twerpbasher Air assist is used to blow cut material through the cut (for cutting plastics), to reduce the chance of fire and it also keeps the lens clean. As air contains oxygen it would not reduce oxidization as far as I can see. Oxygen is used when cutting steel with a CO2 lasers however this laser could probably only cut thin foils even with oxygen.

twerpbasher: @thadude1337 Oxygen would not make any sense, the main point of providing air would be to reduce oxidation! Oxidation leaves ugly cuts, or no cut in materials which have oxides with higher melting points.

LPFthings: @irfanullakr Yes, it blows all the burnt material and smoke out of the way

thadude1337: @irfanullakr it could be any number of things, oxygen is one of them but i have no idea what that laser is using

Irfan Ulla: what is the tube supplying - air???

hack335: Tak, na różnych podzespołach. Ale już sprzedałem i kupiłem profesjonalną maszynę ;)

Anubis jack: Sam go zrobiłeś ? :) (właściwie to ją )

SpecklePattern: @erwinito1 If you ask something like that you should askj for specific material. 1 - 2 mm (fast cutting) for like steel would me a monster laser but so impossible for plastic. Lasers are very sensitive to the wavelength they are using and to the permittivity (type) of cutted the material.

erwinito1: what is the cutting thickness on the laser?1 - 2 mm?
