Hello,
I have 130W 500x700mm Chinese laser and laser head is getting hot after 10-15 minutes of cutting.I align laser beam on all 3 mirrors and laser beam hitting center of nozzle.I place tape around holeon head (where laser beam hitting mirror 3) and noticed something like reflection back from mirror 3 and reflection is hitting bottom of the hole.Any sugestion how to solve this because then head is hot laser cant cut well.Laser head have Mo mirror inside.
Thanks in advance

I cut with 65% power,laser beam hit center of mirror on every position and I use air compressor and solenoid valve to blow smoke

I would change the mirrors out if you can’t find where it’s hitting metal. Be careful working around a beam that’s deflecting somewhere.
