Re: Help with winch wiring and cable gauge
CJDave and the gang are correct about the welding cable! That is a secret that seems to be getting out lately.
Welding cable is finer stranded, so it will carry more amperage, and most welding cable is all virgin copper instead of the alloy mixes that seem to be creeping in and passed off as 'battery' cables.
If you take care and look the selections over, you will find that some welding cable comes with a rubber type insulation instead of the slick plastic type insulation normally found on 'battery' cables. The rubber type insulation is much more abrasion resistant, a better electrical insulator and is easier to bend in the winter, (a real plus when used a jumper cables in the winter)
Virgin copper solders much better, and I haven't seen a good welding shop that can't supply you with just about any kind of ends you may need.
Don't forget the heat shrink tubing to seal the crimp or solder joints, and make the installation look much nicer.
Happy trails. Aaron.
