TIG Tip: How to Set your Torch for Welding in Recessed Holes
What you will see in this episode:
There are hundreds of different setups you can have for different applications in TIG welding. We had a question from a viewer on how you would go about setting up your torch if you had to weld in a narrow hole that is more than an inch deep. There are a couple of different options, but perhaps the easiest and most inexpensive option is using a "reduced neck cup" kit.
When switching to a reduced neck cup you need to remember that it is not as simple as switching the cup and starting to weld. You will need to reduce your argon gas flow to about 7 -- 8 CFH. You also want to be sure that you only have a tungsten stick out of about 1/8". If you go any further than 1/8" you are going to experience turbulence in your weld.
In addition to switching the cup on your torch, you are going to want to make sure you have a flex head. In this demonstration, Wyatt is using a 17f torch. The reason you want to make sure your torch is flexible is because when you are trying to maneuver your torch while it is inside a hole; it is important to have your torch in a comfortable position where you can see what is happening.
For additional information on this setup or if you would like to purchase the kit, contact Wyatt at TIG where you can purchase a kit, visit http://www.weld.com/index.php/mr-tig/92-tig-tip-how-to-set-your-torch-for-welding-in-recessed-holes
