PCW-250型CO_2焊机是采用脉动送丝机构,它不但具有一般CO_2焊机的优点,而且还有其独特之处。但是由于该焊机对焊丝的质量要求较严,而我厂使用的焊丝油污清除得不够彻底,钢球和保持架之间经常被油泥粘住。这就会使机器运转不灵活,送丝不稳定;钢球的耐磨性能差,更换次数多,增加了维修工作量;另外,由于焊枪的软管是固定在焊机上的,但活动范围小,限制了作业面积。因而这种焊机在我厂使用很短一段时间,就因不太适
PCW-250 CO_2 welder is a pulsating wire feeder, which not only has the advantages of the general CO_2 welder, but also its unique. However, due to the strict requirements of the welding machine on the quality of the welding wire, the oil stains of the welding wire used by our factory are not completely removed, and the sludge often sticks between the steel ball and the cage. This will make the machine run inflexible, feeding wire instability; poor wear resistance of steel ball, the replacement of a number of more, increasing the maintenance workload; In addition, the torch hose is fixed on the welder, but the scope of activities Small, limited work area. Therefore, this machine used in our factory for a short period of time, because not suitable
