Description
Technical Field
[0001] The utility model belongs to the technical field of welding, and in particular relates to a magnetic grounding device for a negative electrode line of an electric welding machine. Background Art
[0002] During the welding operation, a grounding clamp is usually used to connect the negative wire of the electric welder to the weldment. However, in some maintenance operations, such as repair welding of pipeline leaks and internal welding of equipment, it is often encountered that there is no position to connect the grounding clamp to the weldment. At this time, a bolt is generally welded to the weldment or equipment, and the negative wire of the electric welder is locked to the bolt with a nut, or the negative pole of the electric welder is connected to a hook, and the negative wire of the electric welder is directly placed on the surface of the weldment. In the above two situations, the operation cycle is long, the labor intensity of the operator is high, and the work efficiency is low. Secondly, the connection between the negative wire of the electric welder and the weldment is prone to virtual connection, causing sparks at the connection. If the position of the negative pole connection of the electric welder is not selected correctly, it is very likely to cause a long welding current loop, causing safety accidents and a high risk factor.
