Between some customers said the light is not on a lot of after welding, the combination of market feedback and our own welding dozens of sets of testing, sampling and LED lights will have a large number of tests, the lamp itself has a problem of possibility is very small. Welding technical proficiency and the cause of the soldering iron burnt and soldering iron electrostatic damage problem is widespread, not letter you can use a multimeter or before welding CR2032 button battery - a test. Welding technology is not good, or welding less at ordinary times, suggest you can also buy more lights. Set aside.
