One scene of the story takes place in a small metal processing factory. The boss here is a craftsman who is passionate about metal art. Faced with the increasingly diverse and personalized needs of customers, he realized that traditional welding equipment is not only bulky but also complex to operate, often requiring completion in fixed workshops, which greatly limits the flexibility and efficiency of creation.

So he introduced the handy welding machine, which quickly became a catalyst for the factory's transformation. Its portability allows this boss to perform welding operations anytime, anywhere, whether in small spaces or complex outdoor environments, making it easy to handle. Its compact size and lightweight weight enable it to be operated with one hand, greatly improving work efficiency. More importantly, the intelligent control system of the handy welding machine allows for the selection of multiple welding modes through simple settings, making it easy for even beginners to quickly get started and greatly reducing the difficulty of operation.
