OVERVIEW

High-Performance Water-Cooled TIG Torch Body

The CK Worldwide 18FX is a premium replacement TIG torch body designed for the professional welder who demands both power and versatility. Part of the industry-standard 18 Series, this torch body is engineered to handle high-amperage applications up to 350 Amps while utilizing a water-cooling system to maintain optimal operating temperatures. This ensures a 100% duty cycle, allowing for continuous welding on heavy-gauge materials without the risk of the torch overheating or becoming uncomfortable to hold.

The standout feature of the 18FX is its flexible head (Flex Head) technology. Unlike rigid torch bodies, the neck of the 18FX can be bent and adjusted to various angles. This capability is critical for pipe welders, aerospace fabricators, and maintenance professionals who frequently encounter joints in restricted or awkward positions. The flexibility does not compromise durability; CK Worldwide utilizes a specialized silicone rubber insulation and a hardened brass head assembly to ensure the torch withstands repeated adjustments and the rigors of the industrial environment.

CK Worldwide is renowned for producing TIG torches that are smaller, lighter, and more durable than competitors. The 18FX exemplifies this with a compact design that accepts standard Series 3 (10N series) consumables, making it easy to find replacement cups, collets, and collet bodies. Whether you are upgrading an existing setup or replacing a damaged torch head, the CK 18FX integrates seamlessly with standard water-cooled power cable systems.
