Centerfire Large Brass Diffuser

The Bernard 510-332 is a Centerfire large brass diffuser designed for MIG welding guns. It features a threaded connection and is compatible with Tweco No. 5 series guns and AccuLock S contact tips. This component simplifies parts management for welding operations.

Fitment and Use Cases

This diffuser suits welders using Tweco Classic No. 5 or compatible models such as 515-116 and 515-332 who need a brass replacement. It is not for operators whose guns use a different connection thread type or a different contact tip series. Buyers needing a diffuser for non-Centerfire systems should look elsewhere.

Maximum Wire Diameter

The unit supports a maximum wire diameter of 0.125 in. This figure determines whether the diffuser matches the wire size used in your application..verify the specification against your welding wire before purchasing.

Questions about this item

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

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?
