I was reading the Owners Manual for my Spectrum 625, I know - what a concept, and found on page 15 that the minimum Grounding Conductor Size is 10 AWG. My 625 has a 12 AWG Ground Cable.

So for you Miller Techs:

1. Is the Manual incorrect in specifying a 10 AWG cable or;

2. Was the incorrect size cable installed on my 625?

Miller is known for using wimpy grounding cables and clamps on their newer machines but this is interesting in that the cable supplied with the machine does not meet their printed specifications.
