Frequently Asked Questions

What materials can both the Monport 40W CO2 and K40 CO2 cut or engrave?

Is the Monport 40W CO2 (40W) much faster than the K40 CO2 (35W)?

Higher wattage typically means faster cutting and the ability to cut thicker material in fewer passes. The Monport 40W CO2 (40W) cuts thicker material in single passes and engraves at higher speeds than the K40 CO2 (35W). For raster engraving the difference is smaller because surface engraving is limited by mechanical scan speed.
