Welding Nozzles
MIG welding nozzles & gas cups from HYW Products. The nozzle surrounds the contact tip and shapes the shielding gas into an even curtain over the weld pool, protecting it from the air. Choosing the right bore size and shape — and keeping it free of spatter — is key to clean, porosity-free welds.

Frequently Asked Questions
What does a MIG nozzle do?
It channels shielding gas into a steady cone around the weld, keeping oxygen out. A larger bore covers more area; a tapered/bottleneck nozzle reaches into tight joints.
Why does my nozzle clog with spatter?
Spatter buildup restricts gas flow and causes porosity. Clean it regularly and use anti-spatter to extend nozzle life.
