TIG Tungsten Contamination Troubleshooting: Black Specks, Arc Wander, Dirty Starts, and Re-Grind Checks
TIG tungsten contamination usually comes from one of five places: the tungsten touched the puddle, the filler rod hit the electrode, shielding gas was interrupted, the tungsten was ground on a dirty…

How to Stop MIG Nozzle Spatter from Blocking Gas Coverage
MIG weld porosity is often blamed on shielding gas settings, but a blocked nozzle can cause the same problem. When spatter builds up inside the MIG gun nozzle, shielding gas flow can…

Bad Gas Coverage in MIG Welds? Replace Your Nozzle
Intro Your MIG welds are porous, and you can see the problem: the shielding gas isn’t covering the weld pool. The arc is exposed, hydrogen from the air contaminates the molten metal,…

TIG Gas Lens Cups Cracking? Replace Them Before Porosity Hits
Intro Your TIG welds are starting to show porosity or inconsistent gas coverage. You’ve checked your argon flow, regulator pressure, and torch angle. Everything checks out—except the welds still look rough. The…
