Standard MB15 M6 E-Cu tips. Binzel originals.
Sold per piece

As the name suggests the contact tip does exactly that, it makes good contact with the welding wire passing the welding current through the contact tip into the welding wire ensuring you are able to weld.  For the weld to be consistent the contact has to be consistent for that reason it is important to replace worn contact tips quickly when worn.
If you use the wrong type or size or a worn contact tip then this can induce arcing between the wire and contact tip which can result  in the wire welding to the contact tip.

Cheap contact tips don't save you money, at Noz-Alls we only sell Binzel original because they will function better and last longer which will save you money, much more than the few pence extra the Binzel original contact tip may cost.  When you need contact tips which are designed to last longer then use Binzel heavy duty contact tips.

M6 threaded with spanner flats on the tip to ensure it may be screwed up tight.
