Melting Tungsten - New to TIG welding
Hello,
Trying my hand at TIG welding, and keep melting the Tungsten. Setup is Dynasty 200DX with Coolmate, Water Cooled Torch, tried different diameter electrodes, welding mild steel, setup according to manual along with rod diameter selection, DCEN seting. The electrode always melts before I can form a large enough pool to form the weld. Any thoughts what I can be doing wrong? Thanks, Luds |

Now, the very TIP of the electrode is supposed to melt, just a little, when you are at the upper end of the current range for that size. What electrodes are you using? Pure Tungsten (EWP)? Those are only good for serious pros who are required to use them in aerospace work. Get some Zirconiated electrodes for Aluminum, and Thoriated or Lanthanated for mild steels. That makes a HUGE difference. Are you absolutely sure you have water flowing through the torch? Are you absolutely sure the current control is working? You should be using 100% Argon, and probably flowing 5-10 Cu Ft/Hr for modest sized electrodes. Jon |

did you turn on the gas? do you have enough gas flow?

Check your gas. My supplier gave me a tank of 20% CO2/80% Argon. I had
blue fits trying to weld AL until I discovered the goof. It works fine on steels. Bugs |

What size electrode? What kind of electrode (pure tungsten, 2%
zirconiated, etc.) What current? What shielding gas? What flow rate? What size filler rod? How thick is the metal you are welding? |
