Attach the ceramic cup and optionally install a gas lens for better shielding.
Finally, connect the torch to argon gas and power source, ensuring secure fittings and proper gas flow.
Learn how each step enhances your weld quality.
Key Takeaways
- Gather and inspect torch body, collet body, collet, back cap, ceramic cup, and tungsten electrode for damage or contamination before assembly.
- Grind tungsten electrode longitudinally with a dedicated grinder to form a clean, sharp tip and insert fully into the collet.
- Screw collet body firmly into torch head front, insert collet correctly, and leave back cap loose for electrode adjustment.
- Tighten back cap to clamp electrode securely, then slide ceramic cup over collet body ensuring a snug fit without overtightening.
- Connect torch gas hose to argon regulator, adjust flow to 10–35 CFH, attach weld cable to power source negative terminal, and check gas flow.
Gather and Prepare TIG Torch Components and Electrode
Start by collecting all essential TIG torch components, including the torch body, collet body, collet, back cap, ceramic cup, and the tungsten electrode.
The torch body serves as the main structural assembly, housing all internal parts. The collet body screws into the torch head’s front, accepting the collet that clamps the tungsten electrode securely.
The back cap threads onto the rear, pressing the collet upward to guarantee proper sealing. The ceramic cup fits over the collet body, providing gas shielding.
Before assembly, inspect each component for damage or contamination. Make sure the tungsten electrode is clean and free from oxidation.
Proper preparation of these components guarantees peak torch performance and arc stability, laying the foundation for precise and reliable TIG welding operations.
Using a non-consumable tungsten electrode ensures the arc remains stable and the welds are clean and precise.
Grind and Insert the Tungsten Electrode Properly
Grind the tungsten electrode to the desired taper or shape using a dedicated grinder, guaranteeing the tip is sharp and free of contamination.
Sharpen the tungsten electrode with a dedicated grinder to ensure a clean, precise tip for optimal welding.
Correct grinding ensures prime arc stability and consistent weld quality.
Once ground, insert the electrode properly by sliding it through the collet body and into the split collet. Keep these key points in mind:
- Grind the electrode longitudinally, avoiding rotational grinding to maintain tip integrity.
- Guarantee the tungsten tip is clean and free of oils or debris before insertion.
- Slide the electrode fully into the collet to prevent movement during welding.
- Maintain proper stickout length for your specific welding application.
Following these steps precisely guarantees a secure, stable electrode setup, critical for high-quality TIG welds.
Using a dedicated tungsten grinder with a diamond wheel helps minimize contamination and extend electrode life.
Install the TIG Torch Collet Body and Collet Correctly
Secure the collet body by screwing it firmly into the front of the torch head before inserting the collet. Make sure it seats flush to prevent gas leaks and maintain structural integrity.
Next, slide the collet into the rear of the collet body, aligning it precisely to accept the tungsten electrode. The collet must fit snugly without excessive force, guaranteeing firm clamping during welding.
Avoid cross-threading during installation to prevent damage to the torch head or collet body. Once positioned, leave the back cap loose initially to allow electrode adjustment.
This setup makes certain the collet can clamp the electrode securely when you tighten the back cap later. Proper installation here is critical for consistent arc stability and electrode retention during TIG welding operations.
Using the correct polarity during welding ensures optimal electrode performance and arc stability, which complements proper torch assembly.
Attach the Ceramic Cup and Install Optional Gas Lens Kit
Once you’ve positioned the electrode and tightened the back cap, slide the ceramic cup over the collet body. Ensure it fits snugly without overtightening to avoid damaging components.
The ceramic cup acts as a heat shield and directs shielding gas effectively around the weld zone. If you opt for a gas lens kit, install it by replacing the standard collet body to enhance gas flow stability and coverage.
Keep these points in mind: gas lens kits improve arc protection and reduce turbulence. The gas lens screws onto the collet body after standard assembly. Use number N style gas lens cups for compatible stubby kits.
Avoid forcing the ceramic cup or gas lens to prevent thread damage. This careful installation guarantees peak shielding and torch performance.
Additionally, maintaining the correct gas flow rates between 10 to 35 CFH ensures optimal shielding and prevents contamination during welding.
Connect TIG Torch Shielding Gas and Power Supply
Before you begin welding, connect the TIG torch to the shielding gas supply and power source to guarantee proper operation. Attach the torch’s gas hose to the argon regulator securely, ensuring no leaks.
Connect the weld cable to the negative (-) terminal of your power source. Adjust the argon regulator to approximately 20 CFH for peak shielding gas flow. Open the torch valve to confirm steady gas flow before striking the arc.
Using argon’s inert atmosphere helps prevent contamination and defects during welding by shielding the molten metal from oxygen and nitrogen.
Verify all connections are tight to maintain consistent performance and safety.

| Gas Hose | Connect to argon regulator |
| Regulator Setting | Adjust to 20 CFH |
| Weld Cable | Attach to power source negative |
| Torch Valve | Open after regulator adjustment |
