Replace first

Common Wear Guidance

1. Verify coolant flow

A hot CK20 often points to cooling flow or cable/hose trouble before cup failure.

2. Match Series 2 front end

Confirm 2 Series standard vs gas lens setup before ordering.

3. Check adapter style

Confirm water-cooled Dinse or Safe-Loc adapter before replacing the torch.

Verify fitment

Check Before Ordering

Confirm torch family first

CK front-end parts are series-specific. Match the torch family before ordering cups, collets, or gas lens parts.

Match tungsten diameter

The collet and collet body must match the tungsten diameter. A near-match can cause poor arc starts or loose tungsten.

Standard vs gas lens

Do not mix standard collet bodies, gas lenses, and large-diameter gas lens cups unless the setup is confirmed.
