I was at the big box and saw that there was something kind of unusual on the warranty resale line. It was a generac generator rated for 17,500w load, 22kw surge. That's like 72 amps of 240v power. I knew that is not something that I see every day and had to ask how much they wanted for it since they offer fairly steep discounts on the turn-ins. All I knew is I was likely going to buy it. After sales tax it's a $3,000 generator when new. I paid $1,110 it out the door. It's got a nema 14-50 receptacle or a "full kva" welding receptacle, L14-30, some 120v receptacles. I found some welding machines use engines almost exactly like this (700cc V-twin) and they use around 1 to 1.3 gallon per hour running welders and air compressors and plasma cutters. Which is what I want it for. My current generator, a 7kw troybilt can't power my plasma cutter at full power and can only run my stick welder at about half power. Lincoln and miller recommend at least a 15kw generator to run a 225 to 235 amp class welding machine like i have at full power.
