I have an annular core with a stack thickness of 40mm, a high 50mm, an inner diameter of 88mm, and an outer diameter of 168mm. I want to go around a spot welder or an electric welder. How many turns and how many turns are there in the first coil? How to calculate?
Whether it is an electric welder or a spot welder, its power is relatively large, at least 3 to 5KW power!The power is mainly related to the sectional area of the core of the transformer and the number of turns of the winding!But your core cross section is only 40*50 = 200mm2, so it is too small to be a common welder! Only do other power transformers, such as power amplifier transformer!
The core section is insufficient, so the power of the welder is not enough,
