在电力建设、化工建设、造船等野外作业和高空作业中,焊工经常遇到远离电焊机施工的情况,调节电流极为不便。北京电力建设公司的焊工师付为解决这一问题,制作了土电阻器,既简单又实用,目前已被广泛地应用在野外施工中。电阻器的制作:电阻丝采用直径5毫米的镍铬合金钢丝4米,钢丝一端接在交流电焊机把线上,另一端接在可旋转的直径57毫米的钢管上,合电焊机闸刀,待钢丝发红即旋转钢管(注意钢丝加热不可太高,呈桔红
In electric power construction, chemical construction, shipbuilding and other field operations and aerial work, welders often encounter the construction away from the welding machine, regulating the current is extremely inconvenient. Beijing Electric Power Construction Corporation, a welder to pay to solve this problem, made of earth resistors, both simple and practical, has been widely used in the field of construction. Resistance of the production: resistance wire diameter 5mm nickel-chromium alloy wire 4 meters, one end of the wire connected to the AC welding machine line, the other end connected to the rotatable diameter of 57 mm of steel pipe, welding machine knife, Be red when the wire is rotating pipe (note that the wire heating can not be too high, was orange
