My GWeike LC 1390 caught fire and burned up last week. It was a little more than 3 months old. Not sure what caused the fire but it was cutting not engraving when it happened and may have been the result of a piece of cork getting popped out of the sheet material and getting dragged around by the laser head while getting "cut" at high power (100W laser operating at 80%). Was fortunate that nothing else was damaged significantly but there was a fair bit of smoke and soot to clean up.
Feeling the need to move forward quickly I found an unused chinese laser by Laser World Laser Engraving cutting machine,Laser marking machine-Beijing yiehesoft YH-G9060 Laser Engraving and Cutting Machine
that is a bit smaller but has pass throughs and was available, closeby, on short notice via craigslist. I would have had to wait at least 4 weeks for a replacement from GWeike and while they were going to discount the replacement they were not giving it to me (My service from them was mediocre all in all but I am not blaming the machine for the fire at this point). So, it would cost a bit more and take some time. I may still pursue this if i am not happy with the smaller size of the machine I just got OR if I can't get it to work.
I need help with some of the different issues this new machine has and with swapping some things out from the old machine.
I realize the fire may be more interesting to comment on and I definitely welcome any good advice but right now its also critical that I get moving again with this new machine and am particularly looking for help with this so here goes
Old machine ran on 110 and new one runs on 220
I am upgrading the new machine from a 60 Watt tube to a 100W tube salvaged from the old machine. I will also and, as I understand it, necessarily swap the power source (attached a pic) out as the one in the new machine is not adequate to power a 100W tube. Of course the physical configuration of the tube itself in the new machine will require some adjustment.
I am using the water chiller from the old machine (also runs on 110) because it is a better chiller.
I would love to have the machine run off 110 but am fine with making it run off 220. It has chinese plugs on it so they will have to be swapped out. I am wondering how to go about swapping power sources. Is this possible since the old power source came from a 110 machine? How much does it matter that this machine is Chinese 220 and runs at a different frequency than US 220? If I have to I can plug the chiller into a 110 socket and run it seperately but obviously would rather the whole thing run off the same outlet. Any ideas?
also got a bunch of spare lenses with the new machine but they are not labeled. Is there a way to identify focal length by looking at lenses?
Obviously, this is a big setback and I am trying to get back going again asap. Any feedback would be most appreciated.
