A digital wire feed system was developed, the result showed wire feed is stable.

研制了数字化送丝系统，送丝稳定。

This paper narrates the usage and maintenance of semi-automatic CO2 welding torch with feed push-wire,including the distance between nozzle and workpiece,wire feed cables of torch,using same size tip with wire,correct usage of soft wire feed tube,bending angle of gooseneck ,installation and uninstallation of gooseneck and inner soft wire feed tube.

对推丝式半自动CO2气体保护焊焊枪的使用与维护进行了详细的叙述，包括：喷嘴至工件间的距离大小，焊枪的送丝电缆，使用与焊丝尺寸一致的导电嘴，送丝软管的正确使用，鹅颈的旋转角度、装卸方法以及内送丝软管的装卸方法等。

The performance of the wire feed system can be crucial to the stability and reproducibility of MIG welding.

由于该系统必须能够平稳送丝，应留意送丝轮和套管。

The pulse wire feed speed is steady, and the highest frequency can reach to 90 Hz.

系统送丝稳定，最高脉动送丝频率可达90Hz。

Unique wire feed motor,steady wire feeding.

独特的送丝电机，送丝更加平稳。

Attenuation when the first land-arc wire feed speed, followed by an immediate cessation of land-arc wire feed.

收弧时先衰减送丝速度，其后收弧立即停止送丝。

Wire structure from the main wire feeder circuit, driver circuit, wire feed motor control circuit, the linear processing circuit and the brake circuit.

送丝结构由送丝主电路、驱动电路、送丝电机控制电路、线性处理电路和制动电路组成。

In this system the motion controlling centers upon regulating the speed of wire feeding and movement of lead screw in each direction.Four motors separately drive the wire-feeding tape roll and the lead screw move respectively following their directions of X, Y, Z axis. If all the motors are controlled by 89C51 directly,it will rise great difficulty for software and hardware implementation. So the suggested solution is to combine the microcomputer with stepper motor driver and control of their motion.

在本系统中运动控制的关键即送丝与各丝杠移动的调节，由四个电机分别驱动X，Y，Z轴方向的丝杠行走以及送丝操作，运动控制部分如果用89C51直接驱动各电机则在软件和硬件实现上都比较困难的，所以选用单片机与步进电机驱动器结合起来控制它们的运动。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
