There is another, perhaps minority, opinion floating around that the 'exterior pathway' argument is valid for high frequency alternating current and/or 'signal' applications while direct current is much less sensitive to surface area. Perhaps someone with specific training/experience will chime in here. OTOH I don't recall ever seeing anyone argue that welding cable was ill-suited for this use, and I'm pretty sure the ruggedness of the insulation and flexibility are not disputed. My suspicion is that most any 4 gauge cable will be sufficiently better than the OE 6 gauge stuff to justify the effort, assuming competently attached and appropriately sized lugs, etc.
