CK Worldwide® CK-150 FX 150 Amp Air-Cooled Flex Head TIG Torch (Choose Options From Above)

Lightweight, compact TIG torch control with a flexible 70° head for better access.
The CK Worldwide® CK-150 FX is a compact 150 Amp air-cooled TIG torch designed for general-purpose welding applications. Its flexible 70° head can be adjusted to improve access to tight or awkward weld joints, while the lightweight, well-balanced body helps improve comfort and torch control.

The CK-150 FX uses standard 3 Series front-end parts commonly shared by 17, 18, and 26 Series TIG torches. Complete torch packages include a two-piece SuperFlex™ power cable with separate machine-side gas and power connections.

Why Welders Choose the CK-150 FX

• Flexible 70° Head: Adjust the torch head to improve access and positioning around difficult weld joints.
• 150 Amp Air-Cooled Performance: Provides professional TIG welding capability without requiring a water cooler.
• 100% Duty Cycle: Rated at 150 Amps ACHF or DCSP at 100% duty cycle.
• Compact & Lightweight: Well-balanced design weighs only 5 oz. (141g).
• 3 Series Consumables: Uses standard front-end parts commonly used with 17, 18, and 26 Series torches.
• Two-Piece SuperFlex™ Cable: Complete packages provide separate gas and power connections at the welding machine.

Choose the Right Configuration

Important: Select the configuration that matches the components you need. The CK-150 FX body-only configuration does not include a handle or power cable. The complete CK-1512NSF FX and CK-1525NSF FX packages include the CK-150H handle and two-piece SuperFlex™ cable.

Flexible Head for Better Joint Access

The flexible 70° head allows the operator to adjust the torch angle to better match the workpiece and welding position. This makes the CK-150 FX especially useful when a standard rigid torch is difficult to position.

• Reach around tubing, fixtures, and other obstructions
• Improve access to confined weld joints
• Adjust the torch angle for different welding positions
• Improve visibility of the tungsten and weld puddle
• Reduce awkward hand and wrist positioning

Two-Piece SuperFlex™ Cable

The complete NSF torch packages use a two-piece cable configuration. This style keeps the gas and welding power connections separate at the welding machine.

Check your welding machine connections before ordering to make sure the two-piece cable configuration matches your equipment.
