在焊接过程中,由于某些原因,焊接工作往往要停頓。因此造成电焊机空轉,白白地消耗电力。我厂周善元等十多位同志集体改进的一种自动开关,可以自动控制直流电焊机的运轉。焊接的时候,只要焊条和电焊机接触,电焊机就可以开始轉动;停焊后3分鐘,电焊机就自动停止运轉。这样就不会由于小的停頓,而使电焊机經常启动,并且可以基本上消除电焊机的空轉。如果我厂所有直流电焊机都装上这种設
In the welding process, due to some reasons, the welding work often have to pause. As a result, the welding machine runs idle and consumes power in vain. Zhou Shan-yuan, such as our plant more than a dozen collective improvement of an automatic switch, you can automatically control the DC welder operation. When welding, as long as the electrode and the welding machine contact, the welding machine can start to rotate; stop welding 3 minutes, the welding machine automatically stops running. This will not be due to a small pause, and make the welder often activated, and can basically eliminate the welding machine idling. If I plant all DC welding machines are equipped with this type of equipment
