Welding cables?

I just the other day talked to a guy whose has a iron working business for decades. Very well experienced
He told me he has a Miller (I think) 120 volt inverter machine that he can run 3/32 7018 wire with and it welds exceptionally well. He uses it on smaller jobs and he is able to take his smaller pickup rather than the bigger rig
Of course he's not welding 8 hours with that machine but for those smaller type jobs he says it can't be beat
Yes, I have a Miller Maxstar 150, probably made me more money, other than my mig. 3/32 7018 rod, I prefer the Lincoln AC/DC version, a little easier to start. That will also run on 230 volt, and it's incredible what you can weld with. 1/8" rod, not a problem. @ 115v 70amps 100% duty, 230v 100amps 100%. Most pipe welding is under 100 amps... And I've welded better part of day with that, still going...
