150watt / 180Watt PK Reci Tube for metal cutting ?

[ddefocy]

My question is : has anyone tried cutting 1mm-2mm carbon steel or Stainless with these tubes.
Using proper gas jet assist (Oxy) and high quality turning mirrors and focus lens + up collimator.

I have been using my 80watt Reci laser now for almost two years , most times between 28/29ma
current and its still running strong . I have a small spot on the OC but it hasn't really affected the
power nor cut quality. But I'm considering upgrading to the RECI 150watt tube and would like to experiment
with O2 metal cutting. Just putting the feelers out to see if its even worth the effort.

Thanks.
