Miller's PRO Series leads the industry in performance and value. These diesel powered engine drives have excellent arc performance for all types of welding jobs, especially for cross-country pipeline welders and any professional welder who needs exceptional arc performance.
The TrailblazerPro 350 and PipePro 304 are diesel‑powered welding machines designed for professional and pipe‑line welders. They feature a 26 HP, 3‑cylinder Kubota engine, 12,000 W peak AC auxiliary power, and a compact, lightweight design that reduces transportation costs.
Both models provide multi‑process capability (Stick, MIG, FCAW, TIG) with a patented Arc Drive and Weld‑at‑Idle technology that improves arc stability while lowering fuel consumption and emissions. The machines also include tool‑less engine access, remote oil drain, and voltage‑regulated auxiliary power for reliable operation of job‑site tools.
