Currently, simple clamping methods or needle-nose pliers are commonly used, which can easily damage the clamps. Another method is to use an integral chuck clamping solution, but this solution has high manufacturing costs and a long production cycle for welding fixtures, making it unsuitable for rapid prototyping of small quantities of square conductor stators and detrimental to the welding work of square conductor stators.

[0003] Therefore, a TIG welding clamp for square conductor stator flat wire is needed to solve the problems mentioned above. Utility Model Content
