Miller Electric Big Blue 300 Pro CC/CV welder generator

Running on a diesel engine from Caterpillar, Deutz or Perkins, Miller Electric's Big Blue 300 Pro CC/CV welder generator delivers 12 kilowatts of generator power and 20- to 410-amp welding output. Miller says compared to the older Pro 300 model, the new unit features improved arc starts and stability. It also provides tailored arc control, allowing the operator to change arc characteristics for specific applications. To extend Big Blue's life, Miller uses a hermetically sealed aluminum case that is impenetrable to dust, salt and moisture.
