Caddy Tig 2200i DC features: Designed for quality TIG welding with a variety of metals. Extremely easy to use – all welding parameters displayed in an easy-to-understand format. ESAB 2-Program function (TA34) – allows pre-programming and program changes during welding. Pulsed TIG feature (TA34) – for greater control of heat input and weld pool. Micro Pulse (TA34) – minimizes area affected by heat, particularly when working with thin metals. ArcPlus II (TA34) improves welding characteristics and simplifies work – produces better weld quality with less clean up. Hot start and Arc force settings (with TA34) – create true MMA welding characteristics. Equipped with large OKC 50 cable connectors – for greater durability. Compact design with impact resistant polymer and aluminum casing – makes unit lightweight and easy to carry. Small size does not compromise vital cooling of internal components. Large heat sinks and innovative design make these Caddy machines run cooler – promotes longer machine life even when used in harsh environments. Designed to keep sensitive interior parts clean and dust free. Built in accordance with IP23 for outdoor use, even in wet-weather conditions – makes machine ideal for on-site work. Equipped with a PFC (Power Factor Correction) circuit – allows the machine to perform a full range of functions on a 16 A fuse, protects against fluctuating input voltage, and makes it safer to use with a generator.
