Replace first
Cracked or contaminated cups are the fastest visual check when gas coverage is poor.
Loose tungsten usually points to the wrong collet size or a worn collet before the whole torch is bad.
If the arc is unstable or gas coverage is poor, confirm the front-end style before buying parts.
Verify fitment
CK front-end parts are series-specific. Match the torch family before ordering cups, collets, or gas lens parts.
The collet and collet body must match the tungsten diameter. A near-match can cause poor arc starts or loose tungsten.
Do not mix standard collet bodies, gas lenses, and large-diameter gas lens cups unless the setup is confirmed.
