The Tweco 24CT-62S (SKU: 1240-1581) is a premium replacement nozzle designed for heavy-duty industrial welding applications. Part of the renowned 24CT series, this nozzle features a 5/8-inch (15.9 mm) bore orifice, which is the standard size for general purpose fabrication, offering a balance between gas conservation and adequate shielding coverage. The unit is manufactured from a robust copper alloy, selected for its superior thermal conductivity and resistance to mechanical wear and spatter adhesion.
A defining characteristic of this model is its coarse thread design. Unlike fine-threaded nozzles that can easily cross-thread or seize due to thermal expansion and spatter buildup, the 24CT coarse threads ensure reliable engagement with the gas diffuser (specifically the 54A series) and facilitate easier removal for maintenance. This nozzle is engineered with a "flush" tip relationship, meaning the contact tip sits flush with the end of the nozzle, suitable for a wide range of short-circuit and spray transfer modes.
This component is an OEM replacement for Tweco Professional Series No. 3 and No. 4 MIG guns, as well as the Spray Master 350 and 450 series. It is also fully compatible with Lincoln Electric Magnum 300 and 400 amperage guns, making it a versatile stock item for shops utilizing mixed equipment fleets. The precision machining ensures concentricity, which is critical for maintaining a laminar gas flow and preventing porosity in the weld metal.
