Function Description:
After power on, press and hold the switch for 2 seconds to turn on There are 4 modes, press and hold the switch for 3 seconds to switch to a a??beepa?? sound and finish Level 1: Low power, green light flashes once 2nd gear: medium power, green light flashes twice Level 3: High power, green light flashes three times 4th gear: automatic mode When the red light is always on, press and hold the switch to turn off the device. ? NOTE: ? If the battery is pretty good and the internal resistance is very low, and then there may be large current overload. If you are not sure about your battery, it`s better to extend the wire by around 1 meter with 2.52 or 42 wire, then it will reduce the risk of power tube burnt. ? Package Included: ? 1x Main Circuit Board 2 x Input Wire 2 x Output Wire(with Welding Pen) 1 x Welding Components Kit ?
