🧰 Function

All these nozzles serve the same essential purpose:

  • Focus shielding gas around the weld pool to exclude oxygen and contaminants.

  • Improve arc stability and reduce spatter/porosity.

  • Protect the torch tip and diffuser from weld spatter.

  • Small differences in size, bore, and length impact gas coverage and access in difficult weld positions.
