一般电焊钳、在连续焊接不长的时间后,就会发热烫手,不能继续使用。我厂船体车间工具修理组同志,经过调查研究,听取使用意见,结合生产实际,将电焊钳加以革新,制成了一种散热式电焊钳(如图),受到了电焊工人的欢迎。散热式电焊钳,在直柄部分加装了十三档散热片,以增加散热面积,从而提高散热效果。散热片用直径为20毫米的黄铜管制作,片间间隔为5毫米。 General welding clamp, continuous welding in the long time, it will heat hot, can not continue to use. After investigation and study, we listened to the opinion of using, combined with the actual production, to reform the welding clamp, and made a kind of cooling type welding clamp (pictured), which was welcomed by the welders. Radiator welding clamp, thirteen files in the straight handle the heat sink, to increase the cooling area, thereby enhancing the cooling effect. The heatsink is made of brass with a diameter of 20 mm and the space between the pieces is 5 mm.
