Questions about this item

How can I confirm the nozzle is seated correctly after installation?

The self-insulated tip should sit flush with the contact tip when fully tightened, and the copper body must show no visible gaps at the insulator joint.

What comes in the package and which consumables must be purchased separately?

The pack contains two Series 21 copper nozzles, part number 12101112; contact tips, diffusers and liners are sold separately.
