Cable size and recomendations please for Champion 4500

[Cormac]

I bought a portable engine driven Champion 4500 earlier this year and have still not fired it up. I am getting ready to and plan to use it for pipe fence, metal buildings, and misc. duties at a farm. I'd like to get the set up right the first time. How much ground cable and what cable size? The same questions for welding cable? I am thinking 25 feet grounding and 75 feet for welding? Is 50' or 100' more practical. I'll probably move it around in the back of the truck. For those familiar with this gas welder, and bear in mind, I have never welded before and will be learning "on the job", any electrode recomendations that will be forgiving for a novice? This is an AC welder and I was suggested to use a 1/8th 6011 and/or 1/8 7018AC? A lot of questions I know, but I definitely appreciate you responses. Thanks

You will probably never need any cable heavier than a 1 or 1/0 . As for lengths, I would suggest 50 foot lenght to start. If you need longer you can always get the quick connects. Please note that you shouldn't have your ground anymore than 10% less in length than your lead due to how close you can get your welder or your ground to the work.
