脉动送丝CO_2焊机(简称PCW-250焊机),包括抽头式焊接电源,弧压送丝调速器,同轴式步距可调的脉动送丝机以及新型的送丝软管,各部分均组装在一个机壳内,焊接电流为60—250安,输出电压为18—40伏,焊丝直径为0.8—1.2毫米,配用一级助推器,送丝距离为20米。该焊机能保证脉动送丝CO_2焊接过程熔滴尺寸均匀,脉动送丝周期与熔滴过渡周期同步,周期中各项参数有较好的重复性,因此焊接过程稳定,焊缝成型良好,飞溅小于3％,此外,在网路电压波动时,对焊接电流有较好的补偿作用。一、同轴式步距可调脉动送丝机同轴式步距可调的适用于长距离送丝
Pulsating wire feed CO_2 welder (referred to as PCW-250 welder), including tapped welding power supply, arc pressure wire feeder governor, coaxial pulsating wire feeder with adjustable step spacing and new wire feeding hose Part are assembled in a case, the welding current is 60-250 amps, the output voltage is 18-40 volts, wire diameter 0.8-1.2 mm, equipped with a booster, wire feeding distance of 20 meters. The welding machine can ensure the droplet size of the pulsating wire feeding CO_2 welding process to be even, the pulsating wire feeding cycle synchronizes with the droplet transfer cycle, and the parameters in the cycle have good repeatability. Therefore, the welding process is stable and the welding wire is well shaped and splashed Less than 3%, in addition, the network voltage fluctuations, the welding current better compensation. First, the coaxial step adjustable pulsating wire feeder Coaxial step adjustable for long-distance wire feed
