Nozzle
Spatter build-up inside the nozzle can restrict shielding gas and collect heat. Clean it regularly, and replace it if it is distorted, cracked, or too loaded with debris.
Nozzle Spa: Clean Spatter and Extend Consumable Life

WeldingStop Consumables Care
Nozzle Spa
Every nozzle has a hard shift. Heat, spatter, smoke, and contact-tip wear slowly change the way a torch behaves. This spa day shows when to clean, inspect, or replace the parts that keep the arc steady.
Spatter Build-up blocks gas flow
Heat Overheating shortens part life
Wear Oval tips affect wire feed
Replace Some parts are not worth saving
Consumable Life Check
Watch the spa score improve as spatter is loosened, the bore is brushed, and worn parts are inspected.

Give the nozzle a treatment.
A nozzle covered in spatter can restrict shielding gas and make the arc less predictable. Some build-up can be cleaned, but contact tips and nozzles still need replacement once the wear goes too far.
Nozzle Spa Clean, inspect, replace
Needs a Spa Day Spatter is choking the nozzle. Start with cleaning, then inspect the wear points.

Shop Notes
What wears out first?
Nozzles, contact tips, diffusers, and liners work together. When one part is dirty or worn, the whole torch can feel less stable: poor gas coverage, inconsistent wire feeding, excess spatter, or burnback.
Contact Tip
The wire passes through this small part constantly. A worn or oval hole can make feeding unstable and hurt electrical contact.
Diffuser
The diffuser helps spread shielding gas. If it is clogged or damaged, the nozzle may look fine while coverage still gets worse.
Liner
A dirty liner can add drag before the wire even reaches the tip. Watch for feeding trouble that keeps returning after tip replacement.
Clean Remove spatter before it blocks the gas path or locks onto the nozzle wall.
Inspect Look for oval contact-tip holes, burn marks, cracked insulators, and distorted nozzles.
Replace Consumables are meant to be consumed. A cheap worn part can make the weld much more expensive.
Keep torch parts ready for the next shift.
