Description

Technical Field

[0001] The utility model relates to the technical field of welding machines, in particular to a small-sized welding machine. Background Art

[0002] A welding machine is a processing machine that can connect separated materials or parts into one body by using the method of local heating. Welding can be divided into soft welding and hard welding. The temperature of soft welding is lower than 450°C, and that of hard welding is higher than 450°C. Hard welding is usually used for metals such as silver, gold, steel, and copper. However, there are certain inconveniences when using existing small-sized welding machines.

[0003] In the Chinese utility model patent application No.: CN201922455919.0, a small-sized aluminum alloy profile welding machine is disclosed. The supporting feet improve the stability of the welding machine, and the height is adjustable to facilitate workers of different heights. The aluminum profile is placed on the support frame, and the air cylinder drives the sliding pressure plate to move to press and fix the aluminum profile. The welding torch welds the aluminum profile. The driving motor drives the screw rod to rotate, and the sliding seat reciprocates along the screw rod through the screw rod transmission principle. The slide rail and the matching chute facilitate improving the stability of the sliding seat. The setting of the camera is used to photograph the welding, which is convenient for controlling the welding. The setting of the display screen is used to display and play the video captured by the camera. However, this welding machine is not convenient for adjusting the position height between workpieces during use, not convenient for making the workpieces contact and weld, and it is not convenient for storing and retrieving the welding torch after welding. During welding, welding slag is likely to accumulate at the tip of the welding torch, and after use, certain heat remains on the surface of the welding torch, which is likely to scald workers. For this reason, we propose a small-sized welding machine. Summary of the Utility Model
