Broken laser tube on new laser - need advice!
Hi friends,
So I ordered my first Chinese laser, the laser itself is nice, it's a Mars-130 with a EFR ZN-1650 tube. However I drew the short straw on the tube. The tube is completely fried, lasted for less than 30 minutes of cutting. You can see the expanding black spot in the photo below and the top part of the tube just strobes when you are cutting, it does not fire the length of the tube (stopped firing correctly when same time as the black spot spread).
The manufacturer says they have an SPT 130w tube in stock but that seems like an awful trade to me. Switching from the EFR 130w I ordered. They claim it will take 45 days to get another EFR tube, which I called them on and they still insist it will take that long. What are you guys thoughts on this, am I getting screwed if I take the SPT tube? Is a reci tube more of a comparable trade if they will not budge on the EFR? What would you suggest?
