Description

Technical Field

[0001] This utility model relates to the field of welding equipment, and more specifically to a dual-pulse gas shielded welding machine for improving the welding efficiency of aluminum materials. Background Technology

[0002] The dual-pulse welding machine is a high-tech, high-precision metal joining device. The working principle of the dual-pulse welding machine is to control the current and welding time by using two different pulse frequencies, thereby achieving a high-strength connection effect during the welding process. The dual-pulse welding machine has the advantages of high precision, high efficiency, high welding quality, and wide applicability, and is widely used in the joining of various metals.

[0003] When welding aluminum, engineers often use their fingers to brace against the wire feed tube, using their fingers as an extra support point to increase hand stability and reduce tremors. However, maintaining this posture for extended periods can easily lead to finger fatigue and soreness, and also carries the risk of burns and bruises.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problems of inconvenient operation and safety hazards caused by using fingers as a support point in existing technologies, this utility model provides a dual-pulse gas shielded welding machine to improve the welding efficiency of aluminum materials. The dual-pulse gas shielded welding machine includes: a welding structure, comprising a handle, a wire feed tube connected to the handle, and a welding nozzle installed at one end of the wire feed tube; an auxiliary support structure, comprising a support part that matches the wire feed tube, and a gripping part that forms a hinged connection with the support part; a protective cloth cover is fitted around the circumferential outer side of the gripping part.

[0006] This invention relates to a dual-pulse gas shielded welding machine for improving aluminum welding efficiency. It includes a welding structure and an auxiliary support structure. The welding structure comprises a handle, a wire feed tube, and a welding nozzle. Welding wire extends from the handle, wire feed tube, and welding nozzle for welding aluminum. The auxiliary support structure includes a support part and a grip part. The support part supports the wire feed tube, while the grip part allows the operator to hold the machine, replacing fingers and enhancing the stability of the welding structure while reducing vibration. A protective cloth cover is provided on the outer circumference of the grip part to prevent spatter from falling onto it and thus preventing burns to the fingers. Through these features, this invention provides a dual-pulse gas shielded welding machine for improving aluminum welding efficiency, allowing the operator to support the wire feed tube instead of using fingers, enhancing the stability of the welding structure, and the protective cloth cover prevents burns to the fingers from spatter.

[0007] Furthermore, a hinge portion is provided at one end of the grip portion near the support portion. The hinge portion includes an abutment plate connected to the grip portion, a mounting base mounted on the abutment plate, and a hinge shaft mounted on the mounting base. A connecting ear is formed on the support portion to form a hinged connection with the hinge shaft.

[0008] Furthermore, a gasket is provided between the connecting ear and the mounting base.

[0009] Furthermore, a limiting plate is detachably provided at one end of the grip near the abutment plate, and the protective cloth cover is positioned between the limiting plate and the abutment plate.

[0010] Furthermore, a leather layer is attached to the circumferential outer side of the support portion.

[0011] Furthermore, the outer layer of the protective fabric cover is formed with a leather layer.

[0012] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0013] The auxiliary support structure includes a support part and a grip part. The support part can support the wire feeding tube, and the grip part can be easily held by the operator, thereby replacing the fingers, enhancing the stability of the welding structure and reducing vibration. A protective cloth cover is provided on the outer circumference of the grip part to prevent spatter from falling onto the grip part and thus preventing spatter from burning the fingers.
