Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a manual arc welding clamp and an electric welding machine capable of adjusting current. Background Art

[0002] Manual arc welding (abbreviated as manual arc welding) is a welding method that uses a manually operated welding rod and the workpiece to be welded as two electrodes, and uses the arc heat between the welding rod and the weldment to melt the metal. When the welding power supply provides a suitable arc voltage and welding current, the arc burns stably, generating high temperature, and the welding rod and the weldment are locally heated to a molten state.

[0003] When manual arc welding is in operation, the operator needs to adjust the current in the following situations. ① Control the arc strength and stability during welding: Current regulation can effectively control the arc strength and stability, ensuring the quality and effect of welding; ② Adapt to different welding requirements: Welding metals of different materials and thicknesses requires different currents, and current regulation can be adjusted according to different requirements. ③ Improve welding efficiency: The appropriate current can increase the welding speed, thereby improving welding efficiency.

[0004] In the prior art, the current regulator is installed on the welding machine. When the working point is far away from the welding machine or the working point is at high altitude, the operator needs to walk close to the welding machine to adjust the current, and then walk or climb to the working point to perform welding operations. This adjustment method is more troublesome. Utility Model Content
