Description

Technical Field

[0001] The utility model relates to the field of welding processing, in particular to a welding gun pressure sensing device. Background Art

[0002] A welding gun is the part that performs the welding operation during the welding process. It is a tool used for gas welding. It is shaped like a gun and has a nozzle at the front end that sprays high-temperature flames as a heat source. It is flexible, convenient, fast, and simple to use.

[0003] The existing welding gun is only hung with one spring. During welding, the pressure of the welding head contacting the welding pad depends entirely on experience and cannot be quantified, which reduces practicality. Utility Model Content
