Just got the new WeldCraft catalogue and it shows the 150 amp DC/115 amp AC air-cooled WP-17 torches & 17F's w/flex head. The WP-150 flex head torch 150 amp DC/105 AC air cooled. It shows their Crafter, WP, AHP (Airco), and Legacy Series Hand-Held Torches. I use four of their torches WP-24, WP-9, WP-17 and WP-26 torches with the Dynasty 200 changing for size and amperage needs.
