Selecting a GTAW Torch

And making it last


7. Looks for cracks or signs of deterioration on the insert, or O-ring, attached to the back cap. If needed, replace to prevent aspiration (pulling of air into the torch body), as this can lead to weld discontinuities.

8. Keep the threads connecting the backcap and torch body clean, look for any signs of wear on the threads, and replace as necessary.

9. Test that the power connector is snugly tightened to the power source to prevent overheating and damage to the torch cable. Also be certain all gas and water fittings are secure to prevent leaks.

10. When using a water-cooled torch, periodically remove the handle to check water connections for leaks that can lead to torch overheating and damage.
