Laser tube question

(Angelalyn75) #1

Hi all, I have a Chinese 80 watt system that has had the cooling tip barely cracked and since repaired. Went to engrave today and no pulse at all. After troubleshooting, we managed to move a wire and get pulse from the tube to the cooling but not past. We also noticed that their is pin sized discoloration in the middle of the tube (see pics). Being machine minded but laser newbies I figured I would see what you guys thought :slight_smile: I am loading pictures now…
