When using a butt welding machine to weld cables, pay attention to the following issues:
1. The power line connecting the welding machine to the power network should not exceed two meters, and the insulation of the line should be guaranteed;
2. The length of the wires connected by the common welding tongs of the butt welding machine is controlled between ten and twenty centimeters;
3. The welding cable cannot be used at will, and should be considered according to the size of the welding current and the required length;
4. The intermediate structure of the welding wire should not exceed three;
5. Do not use metal structures or metal objects such as pipes as lapped wires at will;
6. In the process of use, the cable will generate heat and generate heat, which requires us to better protect it to avoid damage to its insulating layer due to high temperature.
