Tweco 12401866 Copper Spot Nozzle

The Tweco 12401866 is a copper spot nozzle supplied in a pack of two. It features a 0.625 in bore diameter and a threaded connection designed for compatible Tweco MIG guns. Rated for medium duty at up to 350 A, it suits MIG welding (GMAW) within a 0 A to 450 A current range.

Fits Tweco Velocity2 and Classic Nozzle Series

This nozzle fits Tweco Velocity2, Classic Nozzle, Spray Master and Supra XT series guns using VTM or VTMA contact tips. It will not suit guns that require a different bore size, connection type or contact tip series. Buyers needing a recessed or flush tip relationship should verify compatibility before purchasing.

0.625 in Bore Diameter Determines Fit

The 0.625 in bore diameter is the critical specification that decides whether this nozzle matches the gun and application. If the welding gun calls for a different bore size or a non-threaded connection, this part will not install correctly. Always confirm the required bore and thread type against the equipment manual.

Questions about this item

How often will the 0.625 in copper nozzle need replacing during medium-duty MIG welding?

Replacement depends on spatter buildup and tip wear during MIG welding use; the nozzle is rated for medium duty with a maximum amperage of 350 A.

What is the first limit reached when running the nozzle continuously at high amperage?

The nozzle carries a 350 A maximum amperage rating for medium-duty MIG welding; sustained operation above that level exceeds its rated capacity.

How much heat does the copper nozzle produce during all-day MIG welding?

The copper nozzle is rated for medium-duty MIG welding up to 350 A maximum amperage and self-insulated; heat output varies with the welding current used.
