Lincoln Electric KP510 TIG Accessory Parts Kit for PTW-20 Torch Instruction Manual

1. Product Overview

The Lincoln Electric KP510 TIG Accessory Parts Kit is designed to provide essential consumables for maintaining and operating PTW-20 TIG torches. This kit includes a variety of components necessary for TIG welding, ensuring you have the right parts on hand for efficient operation.

The kit contains collets, collet bodies, a back cap, alumina nozzles, and tungsten electrodes in various sizes. All components are organized within a durable, reclosable box for convenient storage and transport.

2. Kit Components

The KP510 kit includes the following parts, designed for compatibility with PTW-20 TIG torches:

• Collets: Components that hold the tungsten electrode securely in place.
• Collet Bodies: These hold the collet and direct the shielding gas flow.
• Back Cap: Seals the back of the torch head and provides a path for the tungsten electrode.
• Alumina Nozzles: Ceramic cups that direct the shielding gas to the weld puddle. Available in various sizes (e.g., #5, #6, #7) to control gas coverage.
• Tungsten Electrodes: Non-consumable electrodes that conduct the welding current. Provided in different diameters.

3. Setup and Installation

This section provides general guidance for installing the accessory parts into a PTW-20 TIG torch. Always refer to your specific TIG torch manual for detailed instructions.

1. Select Components: Choose the appropriate size of collet, collet body, alumina nozzle, and tungsten electrode based on your welding application and current requirements.
2. Install Collet Body: Thread the selected collet body into the torch head. Ensure it is finger-tight.
3. Insert Collet and Tungsten: Insert the chosen collet into the collet body. Then, slide the tungsten electrode through the collet and collet body from the back of the torch.
4. Attach Back Cap: Thread the back cap onto the torch body, tightening it to secure the tungsten electrode. Adjust the tungsten stick-out as needed.
5. Attach Alumina Nozzle: Push or thread the selected alumina nozzle onto the front of the torch head, ensuring a snug fit.
6. Gas Connection: Verify that the shielding gas connection to the torch is secure and free from leaks.

Note: Proper installation of these components is crucial for effective shielding gas coverage and stable arc performance. Incorrect assembly can lead to poor weld quality.

4. Operating Considerations

Once the accessory parts are correctly installed, consider the following for optimal TIG welding performance:

• Tungsten Preparation: Ensure your tungsten electrode is properly ground to the correct taper for your application.
• Shielding Gas Flow: Set the shielding gas flow rate according to the nozzle size and welding current. Insufficient flow can lead to porosity.
• Nozzle Selection: Use the appropriate nozzle size for the joint configuration and desired gas coverage. Larger nozzles provide wider gas coverage.
• Current Settings: Adjust welding current based on material thickness and tungsten diameter.

5. Maintenance

Regular maintenance of your TIG torch accessories ensures consistent welding performance and extends the life of your equipment.

• Inspect Alumina Nozzles: Regularly check nozzles for cracks, chips, or excessive spatter buildup. Replace damaged nozzles to maintain proper gas shielding.
• Clean Collets and Collet Bodies: Remove any spatter or debris from collets and collet bodies. Ensure they are clean to allow for proper tungsten seating and gas flow.
• Tungsten Replacement: Replace tungsten electrodes when they become contaminated, blunted, or too short for effective grinding.
• Storage: Store unused components in the provided reclosable box to protect them from dust and damage.
