100A Digital Lcd Double Pulse Encoder Spot Welder Machine Time Control Board

III. Usage method: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 the future, as long as the module power transformer is not replaced, there is no need to recalibrate. Of course, when you feel that the display voltage is wrong and it can be calibrated. The following are the mains voltages that are not calibrated and displayed during operation Pay attention to the safe use of the high voltage part during installation. When the usage frequency and power are high, silicon control rectifier requires external radiator to disspate heat.The power of the module driving load depends on the power of silicon control rectifier (SCR). BAT41 (40A) can carry a microwave oven transformer, BAT100 (100A) can carry two microwave oven transformers, and the recommended one for Loop transformer is 100A. Precautions for use:This module DIY needs to have certain electrician knowledge, if you are complete freshman, please refer to the electrician's knowledge before you start. Do not know the welding time and power of the welded parts, it is recommended that the welding time and power be adjusted from small to upper to avoid dae to the welding pen.Fault cause and troubleshooting,The electricity supply does not match the actual electricity voltage: re-voltage calibration. The solder joint is not secure or soldered: adjust welding time and power until satisfactory results are achieved.Can be set to save the last operation, the module double pulse trigger, turn off any set of trigger time, you can change double pulse to single pulse 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 change of power supply, and the electric voltage of about 1 second can be displayed when triggered, so that the effective heat of welding is consistent 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 visual 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 storage parameters, can be stored even the electricity power 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 electricity by optical coupling, and design a reliable circuit for zero-crossing detection and voltage detection to ensure the accurate phase shift of silicon control rectifier (SCR), which can be compatible with 40A-100A bidirectional silicon control rectifier (SCR). 9-12 V AC power input (using AC transformers, other such as DC, can cause zero-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.
