With high-capacity capacitor charging and discharging, can you do a spot welder, how to do, please point out /?
Spot welding machine current is very large, the voltage is relatively low, I think there is a Fala capacitor, you can try, the ordinary pressure 2.7~, hundreds of V range, the higher the voltage, the capacity can be said to be very large,If there is a condition, I still suggest to buy a small type alternating current welding machine, homemade spot welder, it is worth a little bit, multi-function, one machine is multi-purpose, and the price is only several hundred pieces
There is no capacitor used in all welders. Not at all
Oh, there are many factors which, if one is doing something wrong, is not up to the effect of welding, you should first go to the theory knowledge of resistance welding, spot welding and then go to the factory to understand the actual, compare and contrast, according to the theory on your idea is OK, but to consider some, a series of, but for sure is that this approach is feasible, hope you will achieve as soon as possible.
The voltage is not too high, below 30V is suitable to use capacitor discharging current, small resistance varieties, Japan has a large current discharge capacitor special, electrolytic capacitor cannot generally be used, easy to lead to interrupt, if found, with multiple capacitor array, parallel capacitor, in addition to the pressure circuit the design for charging the capacitor to adjust the capacitance energy storage size, with different thickness of the workpiece, condenser type spot welder I only met with little dental stainless steel wire, the discharge current is only 0.5 below the welding wire, the specific capacitance of the capacitor, but also forget is not expensive, can use different capacity, different voltage to test a few times, small capacity low voltage to gradually experiment, how have the general voltage from several thousands of micro method, V. From the capacitor to the spot contact line should be thick enough, dental point fine wire, is to use one centimeter in diameter of the brass rod, transformer spot welder I did also, with the brass tube diameter of 6 cm, inside water, little chicken cage with..
