Miller DIALARC HF Welder 200/230/460Volts 1Phase 60Hz 103/90/45Amperes

The Miller Dialarc HF is a heavy-duty, transformer-based AC/DC welding power source designed for professional TIG (GTAW) and Stick (SMAW) welding. Featuring high-frequency arc starting, the Dialarc HF delivers smooth, consistent arc performance and non-contact starts — ideal for precision TIG work on aluminum, stainless steel, and other metals.
Built for industrial reliability, this machine combines rugged construction with simple, durable controls. The “HF” model provides high-frequency stabilization for superior arc starts and reduced tungsten contamination. With both AC and DC output, operators can tackle a wide range of welding applications, from light fabrication to heavy repair and maintenance work.
