利用“口”型低压变压器,铁芯面积282.7平方厘米,两边线圈各550匝,铜线直径为1.88毫米,漆包线直径为2毫米,两线圈串联起来,如图1,然后,再用φ8毫米的紫铜棍绕成两盘外径135毫米6匝并联在一起,接通在导电铜架上。再把火线和地线分开,接到左右550匝线圈上。地线要接到焊接机外壳上和自耦调压变压器上,它们的规格如表1和表2。然后,把自耦调压变压器接线处用胶皮罩起来,防止触
Using “mouth” type low-voltage transformers, iron core area of 282.7 square centimeters, 550 turns of both coils, copper wire diameter of 1.88 millimeters, enameled wire diameter of 2 millimeters, two coils connected in series, as shown in Figure 1, and then, then φ8 Millimeters of copper rods are wound into two discs with outer diameters of 135 mm and 6 inches in parallel and connected to a conductive copper frame. Then separate the FireWire and the ground wire and receive the 550 turns of the left and right coils. The ground wire should be connected to the welding machine shell and the auto-connected voltage transformer. Their specifications are shown in Table 1 and Table 2. Then, cover the autotransformer transformer wiring with rubber cover to prevent contact.
