This is an Airco (Miller) Model 2.25A/DDG-ADE-LA Industrial Welder. This welder is driven by a twin cylinder Kohler engine with electric start. This bad boy has 100% duty cycle on AC or DC welding. I had a health issue that kept me from using this welder for several years. It will start if gas is poured directly into the carb, but the carb itself is not functioning. Old gas gummed it up, I'm sure, so it will need to be removed/cleaned and or rebuilt. The battery is also old and very weak. Asking $600. The copper in the ground and work cables is worth $300+ in scrap.
