电焊工都知道,电焊钳使用时间越长,钳口磨损就越严重,电焊钳上弹簧伸长,弹力减小,钳口之间的间隙加大,直到钳口夹持不住电焊条,电焊钳即报废。在这种情况下,报废的电焊钳就没什么用了。但是,在电焊时还有一根搭铁线,焊工往往为搭铁不牢而烦恼,焊工要么直接用裸露铜线搭铁;要么用一块薄铁板联接在铜线上,再用薄铁板与焊件接触。 生产实际证明以上两种搭铁方法效果都不理想,前一种搭铁方法铜线磨损太快,工作效率低;后一种搭铁方法焊接时电阻增大,搭铁线容易过热,且导电性能差。此时,如果我们用报废的电焊钳接在搭铁线上,就可以解决焊工在操作时搭铁不 Welders know that the longer the use of welding clamp, the more severe wear jaws, the spring on the welding clamp elongation, elasticity decreases, the gap between the jaws increases until the jaws can not hold the welding electrodes, welding The clamp is scrapped. In this case, scrapped welding clamps are useless. However, in the welding there is also a ground wire, welders are often inconvenient to take over the ground trouble, welders either directly with bare copper ground; or with a thin iron plate connected to the copper, and then thin iron plate and Weldment contact. The actual production proved that the above two ground methods are ineffective, the former method of ground copper wear too fast, low efficiency; the latter method of welding resistance increases, ground wire is easy to overheat, and conductive Poor performance. At this point, if we use the scrapped welding clamps on the ground wire, you can solve the welder in the operation of the ground does not
