Welding Question

[LOAF]

Sorry if I put it in the wrong spot.. But here goes

Picked up a new Lincoln Welder (100 HD)but was missing a couple of things..

Its a flux core mig, but can be adapted to go gas..

What I have a question on is the Work Wire (Grounding Wire) was missing..

I know I can pick up the clamps for cheap but not sure what guage wire came it the welder.. I figure I can make my own wire by buying the wire seperate and the clamp..

Any suggestions on what guage to use or shoud I just pick up the replacement wire via Lincoln.. Will heavy guage Automotive Power Wire work.. I think its like 4 guage or something.

I am very excited as no I can weld in my supports to take the vert body off, and do the pans throught out the winter..


Thanks
