Miller Bobcat 230 3-Phase Gas Welder Generator, Kohler, 230A, 8,500W, 907842
The Miller Bobcat 230 3-Phase is a gas welder generator rated 230 A at a 100% duty cycle for stick, MIG and flux-cored welding. Three-phase and single-phase auxiliary outputs are each 8,500 W continuous and 10,000 W peak, and Miller points to 480-volt three-phase pivot irrigation systems among its farm, ranch and maintenance uses.
This engine-driven welder is rated 230 A at 29.2 V for CC/DC stick (SMAW) and 230 A at 25.5 V for CV/DC MIG (GMAW) and flux-cored welding (FCAW), both at a 100% duty cycle, across a 20-230 A range on steel and stainless steel. Full auxiliary power is available at any weld setting, GFCI protection is included, and arcs start easily with less spatter.
A 23.5 hp Kohler gasoline engine idles at 2300 RPM, welds at 3600 RPM and draws from an 11 gallon tank. The welder/generator weighs over 100 pounds less than previous models and is 13 percent smaller, freeing truck space and payload, and a digital interface speeds setup. A lift eye is standard, with running gear or a cart and a trailer optional.
