Why It’s Important

Even though it’s a single consumable, the nozzle is critical to your welding torch’s performance. A worn or incorrect nozzle can compromise gas coverage, lead to inconsistent arcs, increased spatter and shorter consumable life. By using the correct Fronius D17 × 79 conical nozzle you maintain shielding integrity, prolong tip and liner life, and support consistent weld quality across jobs.
