How to prep Welding cable for a low resistance splice, part 4 | ||

This is what the finished splice should look like. | ||

To test the splice resistance a current of 75.7 amps1 was sent through two similar lengths of cable, one with a splice and one without. The voltage drop across the two was measured using a Fluke 8842A multimeter, accurate to 5 digits on the millivolt scale. | ||

(6.8mv/75.7)-(6.4mv/75.7) ~ 5 x10-6 ohms (from the average of many measurements). | |||||||||||||

1. The seemingly odd number 75.7 was used because the amp meter was recalibrated after testing and found to be reading 50 amps at an actual value of 75.7 | ||
