Installation Steps:
- Prepare the Plasma Torch: Ensure your plasma torch is disconnected from any power source. Remove any existing accessories from the torch head if necessary.
- Attach the Guide Wheel: Position the COOLHOOD Roller Guide Wheel around the head of your plasma torch. The inner diameter of the guide wheel is adjustable to fit torch heads within the 18-23mm range.
- Adjust Tightness: Use the screws on the guide wheel to adjust its tightness around the torch head. Ensure it is securely fastened but not overtightened, allowing for smooth movement.
- Set Height: Adjust the height of the guide wheel rollers using the adjustment mechanism. The height can be set between 22-45mm, depending on the desired cutting distance and material thickness.
- Verify Stability: Gently test the guide wheel to ensure it is stable and the rollers move freely.

5. Operating Instructions
Once the Roller Guide Wheel is securely installed and adjusted to the desired height, it aids in maintaining a consistent standoff distance during plasma cutting.
- Power On: Connect your plasma cutter to the power source and turn it on according to its manufacturer's instructions.
- Position the Torch: Place the plasma torch with the attached guide wheel onto the workpiece. The rollers should rest firmly on the material surface, establishing the set standoff distance.
- Initiate Cut: Activate the plasma torch and begin your cut, guiding the torch smoothly along the desired path. The guide wheel will help maintain a consistent height, resulting in a cleaner and more precise cut.
- Monitor Performance: Observe the cutting process. If the cut quality is inconsistent, re-evaluate the guide wheel height and torch speed.
