Why does the soft connection of UN1S iron wire butt welding machine use red copper sheet-Xinxing Welding

The characteristics of the copper soft connection of UN1S iron wire butt welding machine are: 1. It has good electrical conductivity and thermal conductivity. The electrical conductivity and thermal conductivity are second only to silver, ranking second. Use it to make it easier for current to conduct to the stage base electrode. 2. Easy to process by hot pressing and cold pressing, the soft connection is made of multiple layers of 0.1 thick copper skin
