| description | The utility model provides a safety protection device for preventing an electric welding machine shell from being not grounded, which comprises a grounding resistance tester arranged in an electric welding machine, a current applying end of the grounding resistance tester is connected to a power line ground wire of the electric welding machine through a lead, and a test switch is arranged on the lead. The measuring end of the grounding resistance tester is connected to the joint of the electric welding machine shell and the ground wire. The device is convenient to judge the grounding condition of the electric welding machine, and production accidents caused by grounding faults of the shell are avoided.
本实用新型提供一种防止电焊机外壳不接地的安全防护装置，包括设置在电焊机内部的接地电阻测试仪，所述接地电阻测试仪的施加电流端通过导线接入电焊机电源线地线，导线上设有试验开关，接地电阻测试仪的测量端接入电焊机外壳地线的连接处。该装置方便判断电焊机接地情况，避免了因外壳接地故障导致的生产事故。 |
