[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] In welding operations, welders typically need to carry various equipment and tools, such as welding machines, gas cylinders, welding wire, fire extinguishers, and auxiliary tools. Traditional methods of transporting welding equipment are often decentralized, with gas cylinders and welding machines carried separately. This is not only inefficient but also difficult to move in confined or complex working environments, increasing labor intensity and operational risks. Furthermore, the welding process requires frequent adjustments to the position of gas cylinders and the direction of wire feed; traditional equipment lacks integrated design, leading to inconvenience in operation and impacting work efficiency. Currently, some welding trolleys exist on the market, but most are simply designed and have limited functionality, failing to meet the demands of welding operations for equipment integration, convenient mobility, and safe operation. For example, some welding trolleys lack effective lifting devices, making gas cylinder handling and securing difficult; their electric drive systems are inadequate, hindering movement and steering; tools and equipment are cluttered and inefficiently stored; and the wire feeder's direction adjustment is inflexible, easily interfering with other components. Furthermore, existing equipment also lacks safety features, such as the absence of fire extinguisher storage and cable protection designs, increasing operational hazards.

This utility model utilizes a modular layout with welding machine compartments on both sides of the chassis, a wire reel at the top, and a toolbox on the side. This centralized storage of welding equipment, power systems, controllers, and auxiliary tools reduces the need for scattered equipment placement on-site, improving the tidiness of the workspace and the efficiency of tool retrieval. The open storage compartments and rack design ensure the safe storage of gas pipelines, preventing tangling or wear. A double-fixed design, including a gas cylinder protective cover and telescopic bracket straps, ensures the stability of gas cylinder transportation. The electric drive system uses a combination of drive wheels and casters, along with a handrail travel switch, enabling flexible movement and precise steering of the welding machine vehicle, reducing the effort required for manual pushing. The integrated charging base and display simplify battery management, and real-time power monitoring prevents work interruptions.
