I’ve been looking at new psu’s for when I upgrade and was wondering is it worth going for a 50watt?
I’ve seen a few comments online about fitting a more powerful tube. Is this do-able and is there any gain in doing it? I know the case would need modification but that’s the simple bit.

Apperantly our 40 watt tubes are actually 30 watt. So upgrading might be useful especially when cutting thick materials. Beware these tubes are longer so you might need to adapt the laser case.

@Paul_de_Groot ​ Thank you, I thought as much but being new to this it’s always best to ask
