💡 What does a 400 amp pure copper welding lead actually handle on a truck?
Pure copper stays handy for transferring massive current without overheating. The metal carries electrons efficiently while resisting acid leaks and road grime.
- Lower resistance means batteries charge faster during cold starts
- Thicker insulation blocks oil splash away from critical connections
- Soft stranded builds bend around tight firewall holes without snapping
