Replace first

Common Wear Guidance

1. Identify the head

Series 2 and Series 3 Flex-Loc heads use different front-end parts.

2. Verify handle and cable

Confirm modular handle, cable, and cooling setup before buying a replacement head.

3. Match the consumable series

Route to Series 2 or Series 3 breakdown only after the head is confirmed.

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.
