Features: This welding machine can weld up to 0.2mm nickel strip, and firmly weld 0.15mm nickel strip, has a wide applications. The welding machine is built with ammeter function that can measure up to 2kA pulse current. This function can detect whether the solder joint quality is good, thus eliminating the defective solder joint. Once the soldering pen is short-circuited, ordinary welding may damage or even blow up the tube, this product will immediately turn off the output at the moment of detecting overcurrent. Power supplys function: This welding machine also can be used to supp-ly power for your mobilephone. 30 levels of intensity can be adjusted and 25 levels of delay can be adjusted, with multiple protections functions such as overshoot, overdischarge overvoltage pro-tection, give you a better using experience.
