Signage-400H Channel letter Hand held fiber laser soldering machine is a handy laser welding machine , which passes high-energy laser light beam through soft fiber cable to one small laser head , the laser can works on some parts hardly to reach. Hand-held laser head is very flexible to use and makes multi-parts welding available.
The laser source is NG:YAG laser, use golden laser cavity, Xenon lamps and red diamond rod.
Regular combination and fixing of metal letters are done via glue, rivets or soldering, but all of them have big disadvanges. Metal letters combined by glue always get loose with time goes by, especially at outdoors. Fixing by rivets sounds good, but not good-looking. Soldering is never a green way of fixing metal letters because of the poisoning gas produced when processing. From any aspect, laser welding is the best solution and the greenest.
We have two way for welding, one is through the normal model, NG:YAG laser head work on the table, the other one is a hand held fiber laser welding head, you can just hold the fiber laser head in your hand, and weld anywhere you like, it is much more convinient to weld large workpieces . See below photo of the hand held fiber laser welding head.
1. Fast welding process; Exclusive or customized fixing jig device; Fast focusing and positioning without a CCD or microscope.
2. A perfect replacement of traditional soldering and TIG, especially when welding work piece smaller than 5cm or bigger than 100cm.
3. With the help of ultrafine positioning rod, you don't need to adjust light spot at smallest corner.
4. Red dot fast positioning with CCD monitor for detail observation
5. Work table adjustable for different size or weight of metal letters.
