The Pro 300 diesel welding generator from Miller Electric features improved reliability through fewer and more robust electronic components. An optional 4-cylinder, 24-hp Deutz engine provides power for using larger electrodes and gouging with carbons up to ¼-inch diameter. Designed for construction fleets, small contractors and pipe-welding applications, the Pro 300 provides 20 to 410 amps of welding power, as well as 12,000 watts of peak generator power. The unit also features a low-fuel shutdown function that shuts down the engine before fuel runs out.
