Hi all,
I have a 50W Chinese Laser Cutter
(This model - 50W CO2 Laser Engraving U Flash Disk Desktop Device Engraver Cutter Special BUY | eBay)
I've been using it for about 6 month. Today a fuse blew off. And every time I change it, it instantly blows off again, so I blew off 6 of 7 fuses in a row.
And I have no idea what can be a problem.
I am using the right kind of fuses. When I bought this machine, the fuse went off the very first day, so I bought a bunch of fuses to replace and it worked for 6 month without a problem.
I've tried to contact technical support before regarding other question, and it is hopeless, to say the least. So I don't think I will get any decent answer from them.
I was using my machine today for around 10 minutes, so it would not be overheated.
I've checked water pump and air pump separately - they are working fine.
Electrical stuff is one of my weakest points. So I really need an advice.
What might be the problem? What can I check? What shall I do (don't want just blow off fuse after fuse without understanding what going on)?
Best regards,
Denis
