Problems solved by technology

The shape of the welding head of the existing drawn-arc welding torch is fixed, and each welding head can only be installed with a corresponding welding material. Generally, a cylindrical or sheet metal block with a matching shape is installed as the welding material. It is relatively simple. When it is necessary to use cylindrical or sheet-shaped molten materials for welding at the same time, two welding torches are required, and the cost is high
[0003] In addition, the existing drawn-arc welding torch generally has the function of gas shielding, but the pipeline for delivering the shielding gas is set separately from the welding circuit, which makes the structure of the whole welding torch complex, and at the same time increases the weight and volume of the welding torch, resulting in the use of inconvenient

Abstract

The invention discloses a replaceable gun head of a multifunctional electric welding gun. The replaceable gun head comprises an electroconductive member made of metal and an insulated connecting member, a mounting groove is arranged on the electroconductive member, an insulated outer cover is covered above the mounting groove to enable a closed cavity to be formed between the electroconductive member and the outer cover, an opening allowing a fusion welding object connected with the electroconductive member to extend out is arranged at the front end of the cavity, and a welding column fixing member used for fixing a columnar fusion welding object or a compressing device used for compressing a sheet fusion welding object is arranged in the cavity. The columnar fusion welding object or the sheet fusion welding object can be mounted on the replaceable gun head by replacing part of accessories, and the replaceable gun head has various functions and can meet using needs of different using occasions.

Description

technical field [0001] The invention relates to the field of electric welding equipment, in particular to a replaceable torch head of a multifunctional electric welding torch. Background technique [0002] Drawn arc welding is to apply high pressure between the welding head of the electric torch and the object to be welded to generate an arc, melt the molten material installed between the welding heads, and weld the object to be welded. The shape of the welding head of the existing drawn-arc welding torch is fixed, and each welding head can only be installed with a corresponding welding material. Generally, a cylindrical or sheet metal block with a matching shape is installed as the welding material. It is relatively simple. When it is necessary to use cylindrical or sheet-shaped molten materials for welding at the same time, two welding torches are required, and the cost is relatively high. [0003] In addition, the existing drawn-arc welding torch generally has the functi...
