In this video I discuss the affects of speed power and air flow and how they if you just change air flow to your engravings how much it can change you look and reduce the contamination on your material. We cover birch plywood, cast and extruded acrylic and 2 color plastic sign material.

Wood results start at 2:55
Acrylic results start at 10:40
2 color Rowmark sign material 16:10

All engraving was done on a Nova 35100 watt co2 laser

You will always want enough air flow to keep your focus lens cool. NEVER turn off your air flow compleatly! You will ruin your focus lens!

I purchased the digital gauge from smc pneumatics model number SMC ISE30A01NL
