根据生产需要,我厂自行设计了一台可以移动的轻便二氧化碳气体保护焊机。其外廓尺寸290×550×720毫米,自重150公斤。经过几年来的使用,性能稳定,效果较好。一、电源焊机主电源由抽头式三相焊接变压器、硅整流二极管、电抗器等组成。主电源电气原理如图1所示。 1.主变压器 1)主要参数输入电压～380伏输出电压 14～30伏容量 6仟伏安接法△/Y 铁芯尺寸 90×316×340毫米硅钢片厚度 0.35毫米 2)线圈的绕制初极边:用φ1.56毫米漆包线,分两
According to production needs, our factory designed a portable light carbon dioxide gas shielded welding machine. The outline size of 290 × 550 × 720 mm, weight 150 kg. After several years of use, stable performance, the effect is better. First, the main power supply welding machine tapped three-phase welding transformers, silicon rectifier diodes, reactors and other components. Main power supply electrical principle is shown as in Fig. 1. Main Transformer 1) Main Parameters Input Voltage ~ 380V Output Voltage 14 ~ 30V Capacity 6 kVA Connection Method △ / Y Core Size 90 × 316 × 340mm Thickness of Silicon Steel Sheet 0.35mm 2) Coil Winding Pole: with φ1.56 mm enameled wire, divided into two
