Heavy-duty connections require heavy-duty solder slugs. Our large 2/0 gauge color-coded solder slugs are the only choice when it comes some of the most demanding electrical loads. As you go up in slug sizes you get better electrical performance over the crimping method. And let's face it: the larger the lug, the more difficult to get a reliable crimp. Designed for heavy to super-utility work trucks, and heavy-duty tow trucks and farm equipment. The proper choice for large marine applications that require better corrosion protection. Bigger slugs give much higher electrical performance than other methods when more current is being demanded. It's simply the better way to go over crimping. More current, higher efficiency, a much more solid connection and far better protection against corrosion. Who can argue with that? 2/0 gauge Solder pellets are easy to use, as this video showing how to utilize a solder slug to make a cable demonstrates.
*Propane or butane torch
*a bottle of flux
*heat shrink tubing (we recomend our Heavy Duty)
*a vice or clamps.
>How to use a solder slug / solder pellet:
*Strip the end of the cable so that the exposed copper reaches the battery terminal bottom
*Place the 2/0 pellet size into the battery terminal, and secure it with a vice
*Slide the heat shrink tube over the 2/0 gauge cable
*Apply several drops of flux to the exposed copper of the cable
*Pre-heat solder to until it melts
*As soon as solder melts, slowly insert the cable while continuing apply heat
*Make sure conection is secure and shrink the tubing over the connection
