A Portable Multifunctional Gas Shielded Welding Torch

Abstract

The invention discloses a portable multi-functional gas shielded welding gun which comprises a gun body, a wire feeding mechanism fixed on the gun body, a metal conveying rod connected with the wire feeding mechanism and a fusion welding head arranged at the front end of the metal conveying rod. A bolt installing base is arranged on the gun body, a detachable conductive rod is arranged through the bolt installing base, the conductive rod is parallel to the metal conveying rod, a conductive auxiliary head is arranged at the front end of the conductive rod, and a nail planting installing hole is formed in the auxiliary head. The welding gun has various functions of double-pole welding wire welding, monopole welding wire welding, plastic nail planting repairing and the like. Aluminum welding performance is better than that of a common gas shielded welding gun, a use range is wide, the welding gun can be applied to various situations, and the practicality is good. Meanwhile, various structures of the welding gun are reasonable in matching and human-friendly, users can conduct various kinds of adjusting and movement in a use process, and the welding gun is popular with the users.

Description

technical field [0001] The invention relates to the field of electric welding equipment, in particular to a portable multifunctional gas shielded welding torch. Background technique [0002] Existing electric welding machines generally include a control host and an electric welding torch. The gas-shielded welding torch that uses welding wire for welding generally sets the welding wire on the control host, and the wire feeding motor on the control host is responsible for conveying the welding wire. The disadvantage of this welding torch is that the welding wire is separated from the welding torch. When long-distance work is required or the welding location is changed, the wire feeding distance is extended, which can easily lead to uneven or weak wire feeding, especially when using soft materials such as aluminum welding wire. . At the same time, if it is necessary to adjust the wire feeding speed during welding, it must be adjusted back to the control host (or an external wi...

AI Technical Summary

Problems solved by technology

The disadvantage of this welding torch is that the welding wire is separated from the welding torch. When long-distance work is required or the welding location is changed, the wire feeding distance is extended, which can easily lead to uneven or weak wire feeding, especially when using soft materials such as aluminum welding wire.

At the same time, if you need to adjust the wire feeding speed during welding, you must return to the control host (or an external wire feeder) to adjust, and the back and forth operation is more troublesome.

[0003] In addition, the existing gas-shielded welding torch generally adopts a single-pole welding torch, and the welding torch has only one fusion welding head connected to the positive electrode of the output power of the welding machine. When welding, the base metal needs to be connected to the negative electrode of the welding power supply through the ground wire to form a circuit, so that it can be carried out normally. Welding, in the application of automobile sheet metal repair, etc., the sheet metal paint must be polished to install the ground wire, which is troublesome to operate

Moreover, the existing gas-shielded welding guns only have one welding mode, and their functions are relatively single, and they can only weld metals, but cannot weld and repair plastics, so they need to be developed and improved.
