CK20-12SF FX - CK20 Flex Head Water-Cooled TIG Torch with 12.5ft Super Flex Cables

Technical Overview: CK20-12SF-FX Water-Cooled Torch

The CK20-12SF-FX is a 250-amp, water-cooled TIG torch assembly from CK Worldwide, belonging to the standard 20 Series family. It is engineered for high-duty cycle applications requiring a compact form factor. The torch body features a Flex Head mechanism, allowing the operator to articulate the torch neck to various angles to accommodate complex joint geometries without compromising gas coverage or electrical conductivity.

Cooling and Duty Cycle

Utilizing a water-cooling system, this torch achieves a 100% duty cycle at 250 Amps (DC) or 250 Amps (AC). The efficient heat dissipation allows the torch head to remain small—comparable to an air-cooled 9 series—while handling more than double the amperage. This makes it the industry standard for precision AC TIG welding on aluminum and heavy-duty DC welding on stainless and carbon steels.

Super Flex Cable Assembly

The "12SF" designation indicates a 12.5-foot cable length equipped with CK's Super Flex technology. The power, water, and gas lines are integrated into a flexible silicone hose assembly with a durable nylon overbraid. This construction eliminates the stiffness associated with traditional rubber or vinyl cables, providing superior maneuverability and resistance to kinking.

Consumable Compatibility

The CK20-12SF-FX utilizes standard 2-Series (also known as 9/20 series) front-end consumables. This ensures broad compatibility with widely available collets, collet bodies, gas lenses, and alumina cups. It is compatible with standard water cooler hookups (typically 5/8"-18 LH for water/gas and standard power block connections).
