Caveman Crimping VS Electric Crimper! 300 amp Test Part 5

This video explores different cable crimping methods, pushing hammer crimping to new levels. Previous tests revealed that simple hammer crimping had lower resistance than professional cables. Further testing showed that cleaning the lug and wire ends with rubbing alcohol significantly reduces resistance, regardless of the crimping method. The experiment involved several techniques: hammer only, hammer crimper, vise grip crimp, and a budget crimper. The hammer only method yielded 26 millivolts, hammer crimper 30 millivolts, vise grip crimp 27.5 millivolts, and the budget crimper achieved 22.1 millivolts. The video then introduces high-end electric crimpers, including a cordless and a corded model capable of using industrial die sets. A hybrid of these, a clone that can use industrial dies, achieved an impressive 18.4 mV on the first try. Despite cleaning, this result only increased by 0.1 mV, though it remained an excellent score. Ultimately, the best results depend on a proper lug, crimper, and, crucially, industrial die sets. Even a less expensive crimper can produce good results with high-quality dies. The video concludes by emphasizing the importance of low resistance and cautioning against potentially high resistance in some professionally made cables.
