Abstract

The invention provides an auxiliary arc striking and arc length control shielded metal arc welding gun system for manual operation. A device comprises a miniature sliding table mechanism capable of driving an electric arc to move up and down, a fixing seat used for installing the miniature sliding table mechanism, a welding clamp used for clamping a welding rod, a grip, a chuck used for connecting a cable and the welding clamp, a Hall voltage sensor used for detecting welding voltage, and a control circuit board used for controlling automatic arc striking, arc length compensation and the like for shielded metal arc welding. The miniature sliding table mechanism can drive an electric arc to slightly move up and down in the length direction of the electric arc or in the direction similar to the length direction of the electric arc when a welding rod is manually fed, so that the length of the welding electric arc is finely adjusted, the arc length change caused by non-uniform feeding speed of the welding rod in the manual shielded metal arc welding process is compensated, the electric arc length is kept unchanged, and the arc stability is improved.

Description

technical field [0001] The invention belongs to the field of welding equipment, and relates to an intelligent electrode arc welding torch system for manual operation, in particular to an intelligent electrode arc welding torch system for manual operation with arc length change compensation. Background technique [0002] As a traditional welding method, manual arc welding still occupies an important place in the welding field because of its advantages of convenient operation and low cost. [0003] As we all know, manual electrode arc welding has difficulty in starting the arc for beginners, and it is easy to break the arc and stick the rod; during the welding process, due to the manual feeding of the electrode, the arc length changes greatly, the welding quality is unstable, and it is also prone to arc breaks. Therefore, the welding quality of the manual electrode arc largely depends on the skill of the operator. [0004] Guo Ning, Du Yongpeng, Feng Jicai and others from Har...
