Questions about this item

Will the Bernard 510-332 diffuser thread onto my existing Tweco No. 5 MIG gun?

Yes, it uses a threaded connection type designed for Tweco No. 5 guns and is compatible with models 510-332, 515-116, 515-332, L515-332, M515-116 and M515-332.

How can I confirm the brass diffuser is seated correctly after installation?

Thread it fully into the gun head until snug; the Centerfire design aligns the AccuLock S contact tip concentrically for consistent gas coverage and wire feed.

Does the box include AccuLock S contact tips or must I buy them separately?

The diffuser is sold as a single brass component; AccuLock S contact tips for up to 0.125 in. wire are not included and must be purchased separately.
