我厂缺乏电阻点焊的設备,焊工孙鴻福等同志利用电弧焊設备加以改装,使它成为既能进行电阻点焊又能进行电弧焊的两用設备。图1是改装后两用設备的总图。原来电弧焊接机的鉄心4纏有初极綫圈10和次級綫圈15。初級綫圈通过导线11接到总电門2上和分电門3上,电門2和3与外綫路1連接。次級綫圈15通过导綫16引向电弧焊接的手把和接地。这一些都是原有的設备。改装后增加了一个水箱13,水箱接有进水管12和出水管14。在水箱的两
I plant the lack of resistance spot welding equipment, welders Sun Hongfu and other comrades use arc welding equipment to be modified, making it both for resistance spot welding and arc welding dual-use equipment. Figure 1 is a general view of a modified dual-use device. The original arc welding machine 鉄 heart 4 wrapped around the primary coil 10 and the secondary coil 15. The primary coil is connected to the main switch 2 and the sub-switch 3 via wires 11, and the switches 2 and 3 are connected to the external line 1. Secondary coil 15 leads through lead 16 to the arc welded handle and to ground. These are the original equipment. After modification, a water tank 13 is added, and the water tank is connected with a water inlet pipe 12 and a water outlet pipe 14. Two in the water tank
