Von We have same crimper. Works great. Are you saying your dies are marked in metric? Ours are AWG sized. I use the lugs from Waytek. They come with the size clearly stamped on them. You can get some with the solder in them if deemed necessary. The only downfall I know to welder cable is color. I think it comes in black...period. However, you can buy colored HD heat shrink from Waytek again and just put 3" or so on the end of the cable to i.d. the + cable. Otherwise, I'm not sure how electrically they differ. It's a great tool, congratulations. |
