Description

Technical Field

[0001] The invention belongs to the technical field of carriage welding, and in particular relates to an automatic welding device for a motorhome carriage with active heat dissipation. Background Art

[0002] An RV combines the functions of both a house and a car, but its attribute is still a car. It is a movable type of vehicle that has the basic facilities necessary for a home. An RV generally refers to a vehicle with a fixed roof, and it has spacious space, is well-equipped, and fully equipped, and is loved by many people who love the outdoors.

[0003] Since RVs have spacious spaces, their carriages need to be built with a large amount of steel. In the process of carriage processing, welding is an indispensable step. Since welding operations take a long time and the current passes through the wire to produce an electrothermal resistance effect, the welding gun of the welding machine will overheat. Continuous overheating operations will cause damage to the welding gun or transfer heat to the wire connection, causing a short circuit. For this reason, it is necessary to provide an RV carriage automatic welding equipment with active heat dissipation, which adopts air cooling and water cooling adaptive methods. According to the temperature change, the heat dissipation method can be selected by itself, thereby ensuring the stable use of the welding gun and reducing the energy consumption of the welding machine. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic welding equipment for a motorhome compartment with active heat dissipation, which adopts an adaptive air cooling and water cooling method and selects the heat dissipation method according to the temperature change, thereby ensuring the stable use of the welding handle and reducing the energy consumption of the welding machine to solve the above technical problems.
