Optical fiber welding machine analysis of these problems from which a few respects?

Optical fiber welding machine analysis of these problems from which a few respects? 1. Welding machine cannot boot the failure cause analysis of the reasons from the following: ( 1) Instrument power supply whether normal ( 2) Instrument 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 errors or motherboard failure or damage to the screen. 2. Welding machine button should without the fault of the cause caused from the following analysis: ( 1) Related key failure ( 2) Illegal operation ( 3) Machine slowly or crash 3. Welding machine can't heating heat shrinkable casing of the cause caused by the fault can be from the following analysis: ( 1) If the temperature of the heater, heat is not enough, such as heat enough just can heat shrinkable casing problem ( 2) Damage (such as heat is not enough, may be heater 3) Check whether the heater power supply is normal. 4. Welding machine power supply battery can't supply the failure cause analysis of the reasons from the following: ( 1) The battery core ( 2) The battery charger is damaged or charging circuit damage ( 3) 5 the charging connection. Welding machine through the introspection of the cause caused by the fault can be from the following analysis: ( 1) Can't damage through self-inspection part, according to the corresponding fault handling ( 2) Application error 6. Crash appeared in the process of welding machine for welding of the cause caused by the fault can be from the following analysis: ( 1) Application error ( 2) Key components instrument poor contact, or voltage instability. ( 3) The mainboard failure
