III. Usage :Voltage calibration:The module has the network voltage compensation function, so the voltage calibration must be carried out when the first machine is installed, and in , as long as the module transformer is not replaced, there is no need to recalibrate. Of course, when you feel the display voltage is wrong and it can be calibrated. The following are the mains voltages are not calibrated and displayed during operation Pay attention to the safe of the high voltage part during installation. When the usage frequency and are high, silicon control rectifier requires external radiator to disspate heat.The of the module driving load depends on the of silicon control rectifier (). BAT41 (40A) can carry a microwave oven transformer, BAT100 (100A) can carry two microwave oven , and the recommended one for Loop transformer is 100A. Precautions for :This module DIY needs to have certain electrician knowledge, if you are complete freshman, please refer to the electrician's knowledge before you . Do not know the welding time and of the welded parts, it is recommended the welding time and be adjusted from small to upper to avoid damage to the welding pen.Fault and troubleshooting,The supply does not match the actual voltage: re-voltage calibration. The solder joint is not secure or soldered: adjust welding time and until satisfactory results are achieved.Can be set to save the last operation, the module double trigger, turn off any set of trigger time, you can change double to single trigger.The main board and the display operation panel are separated, and the outer casing can be flexibly assembled. With grid voltage compensation, the output of compensation can be automatically adjusted according to the of supply, and the electric voltage of about 1 second can be displayed when triggered, so the effective heat of welding is with the welding parameters, and the welding spot is uniform. DIY or simple battery welder development welding. Welding of a single battery or battery pack. Multi-group data 12864 display, intuitive operation, convenient, single encoder parameter adjustment can make the operation simple and fast. With 0-9999 welding counting function, with 5 groups of sample parameters, can be stored even the is off, the number of wleding could be seen just by a glance. Time input 0-99 cycle (1 cycle is 20ms, for example, the adjustment value is 50, which is the welding time 1 second.), the stop time between 2 weldings is 0-99 cycles (1 cycle is 20ms, such as interval value 50, It is the interval of 1 second.) adjustable. Welding strength 30%-99% is adjustable. The module can isolate the strong and weak by optical coupling, and design a reliable circuit for -crossing detection and voltage detection to the phase shift of silicon control rectifier (), which can be with 40A-100A bidirectional silicon control rectifier (). 9-12 V AC input (using AC , other such as DC, can -crossing detection failure, can not trigger.) colour:green Material:Metal + PC Package Contents: 1 * Main Board 1 * Display Board 1 * Cable Only the above package content, other products are not included. Note: Light and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
