视频中展示了一位工人在操作焊接设备的场景。画面中可以看到工人的手部特写，他正握着一个红色的焊接电源控制器。工人的手腕上戴着一副防护手套，显示出他在进行焊接工作时的安全意识。背景中可以看到一些金属杆和工具散落在地面上，地面是水泥材质，显得有些粗糙和脏污。另一位穿着蓝色牛仔裤和绿色鞋子的人站在旁边，似乎在观察或等待。整个场景给人一种工业车间的感觉，充满了实用性和功能性。
The video shows a close-up view of a person's hand holding a red and yellow tool, possibly a welding machine or a similar device. The person is wearing a brown sleeve, and their hand is positioned as if they are about to use the tool. In the background, there are several metal rods and another person standing nearby, partially visible from the knees down. The setting appears to be a workshop or a construction site with a concrete floor. The overall scene suggests that some kind of manual work or repair is about to take place.
In a dimly lit, dusty environment with scattered metal rods on the ground, a person holds a red device with both hands. The person raises the device, bringing it closer to their face. The device has several buttons and a small screen, which the person begins to press. As the person continues to press the buttons, the device's screen lights up, indicating it has been turned on.
