Micor 160 is 230v/Genny and Battery
Micor 180 is 115/230/Genny and Battery
Wasp have some good online pricing.
I'm in the market for a new one .
You woud maybe get away with a 8kva diesel maybe a little smaller but the general recommendation is 10kva plus with an avr.Roughly what size Genny would I need for a 160 amp inverter welder
