Hello Everyone,

I read elsewhere that the bigger Size Wattage CO2 Tubes are unsuitable for engraving and a 150w CO2 Tube can be reduced down to as far as 16hours if its constantly used for only engraving.

How true is this? I have a 130w and if this is true would want to add a second Laser connected to a 40W CO2 Tube to use just for engraving. I have seen this setup on YouTube but haven't found any plans or instructions on doing this.
