Weldcraft brings you the ultimate welding work-horse designed for handling the toughest production and maintenance welding jobs. These natural air-cooled welding transformers have Class H insulation and stepless current regulation. They possess excellent arc characteristics, ensuring smooth and stable arc, better metal transfer, low spatter levels, excellent arc-striking (due to high OCV) and prevent electrodes from freezing due to their starting current surge. These features keep us a step above the rest.
