Welding machine cannot boot, buttons have no response, not heating heat shrinkable casing, the cell does not power supply, power supply can't through the introspection, appeared in the process of welding crash! 1, the welding machine cannot boot the problems caused by the factors to analysis from the following points: ( 1) Exterior power supply is normal, 2) Appearance of the switch is normal ( 3) Boot can see motherboard information, such as not may be motherboard damage ( 4) No reaction after boot if you can see the main information, or death, may be program mistakes or motherboard problems or damage to the screen, 2, welding machine button should free problem caused by the factors to analysis from the following points: ( 1) The key failure ( 2) Illegal operation ( 3) Machine slowly or crash 3, welding machine can't heating heat shrinkable casing caused by the fault factors to analysis from the following points: ( 1) How the temperature of the heater, heat no, such as heat enough just can heat shrinkable casing problem ( 2) Damage (such as heat no, may be heater 3) Check the heater power supply is normal 4, welding machine power supply battery can't supply the problems caused by the factors to analysis from the following points: ( 1) The battery core ( 2) The battery charger is damaged or charging circuit damage ( 3) Charging connection bad 5, self-inspection of welding machine can't pass, the problems caused by the factors to analysis from the following points: ( 1) Can't damage after self-inspection of part, according to the corresponding fault handling ( 2) Program error 6 appeared in the process of welding, welding machine crash caused by the fault factors to analysis from the following points: ( 1) Program error ( 2) Key components looks poor contact, or voltage instability. ( 3) The mainboard problem
