Swivel Head Adjustment Screw: Fixing Loose TIG Torches

Quick Answer

Tighten a loose TIG torch swivel head by adjusting the screw inside the head assembly, and replace the o-ring if the head still wobbles or leaks gas.

Steps to Fix a Loose TIG Torch Swivel Head

1. Step 1: Remove the Swivel Head: Unscrew the swivel head from the torch body. Lay it on a clean work surface with the adjustment screw facing up. Work in a well-lit area to avoid losing small parts.
2. Step 2: Tighten the Adjustment Screw: Use a small flathead screwdriver to turn the adjustment screw clockwise in quarter-turn increments. Stop when the head moves smoothly with slight resistance. Do not over-tighten – the screw should not be cranked down hard.
3. Step 3: Inspect the O-Ring: Check the o-ring inside the swivel head for cracks, flattening, or wear. A damaged o-ring causes gas leaks regardless of screw tension. If the o-ring looks worn, replace it with the new one from the adjustment screw kit.
4. Step 4: Reassemble and Test: Screw the swivel head back onto the torch. Turn on the gas and check for leaks with a soap solution. Rotate the head to confirm smooth, snug movement. A small gas leak at the swivel joint usually means the o-ring needs replacement.
