我厂于1976年初买进一台GD200型直流CO_2气体保护焊半自动焊机。由于送丝机构不稳定,多次检修不能解决;焊把约重2.5～3.0公斤,操作不方便,焊工不愿使用,因此焊机一直未用。根据我厂生产的特点,即在固定工作台上焊接尺寸较小(不超过500×500×500mm)的薄板结构。所以原手柄拉丝式焊枪可作长距离移动的优点在我厂不适用。为此我们对焊把及拉丝机构进行了改革。改革后的送丝机构为推丝机构。改革
I plant in early 1976 bought a GD200 DC CO_2 gas welding semi-automatic welding machine. As the wire feeding instability, multiple maintenance can not be resolved; welding about 2.5 to 3.0 kg weight, inconvenient operation, the welder reluctant to use, so the machine has not been used. According to the characteristics of our factory production, that is welded on a fixed table size smaller (not more than 500 × 500 × 500mm) sheet structure. Therefore, the original handle-type welding torch for the advantages of long-distance mobile plant does not apply in my plant. To this end we have carried out the reform of the welding rod and wire drawing mechanism. After the reform of wire feeding agencies for the wire. reform
