12V 35ED Portable Spot Welder Module Intelligent Control Spot Welder for Electronics and Model Repair

Function test 1 The spot welder board can be powered by lithium battery 2S 3S or 4S lead acid battery and the power supply voltage needs to be between 6 5V 16V not in this range may cause damage to the board components 2 Connect the line according to the connection diagram After powering on select the appropriate capacity magnification and parameter such as gear position observe whether the indicator light is normal 3 The pressure applied to the nickel sheet by welding must be moderate and the contact surface between the nickel sheet and the battery must be free of oil raised and oxidized Practice on the surface of iron and stainless steel until the 0 1mm nickel sheet can not be torn off indicating that you are familiar with it and can weld battery operations 4 When the battery temperature is too low it may cause the performance of the battery to drop and preheat more than a dozen solder joints After that the best performance can be restored It is best to use it in a warm room After charging you can wake up and turn on again Welding principle This product uses a high rate lithium battery as the power source and uses the contact point of the spot welder to contact the substrateResistor melts the contact points at the moment of heat generated by the thermal effect of a large current thereby bonding them together P I 2 R Whether the welding is good or not the pressure is very important during spot welding The pressure is too high and the resistance of
