Tweco Nozzle – #4 Nozzle (24CT62) and Tweco #5 Nozzle (25CT62)

Price range: R142,03 through R156,98

Specifications & Comparison

Property 24CT62 (Tweco #4) 25CT62 (Tweco #5)
Thread Type Coarse Thread (“CT”) for #4 series guns (“Tweco #4 / 14‑series style”) Coarse Thread for #5 series guns (“Tweco #5 / 25 series style”)
Bore / Internal Diameter Common version: approx 0.625 in bore (≈ 16 mm) for many 24CT62 nozzles. Also ~0.625 in bore for standard 25CT62 versions; used for wire sizes in MIG that demand more gas flow & larger contact tip protection.
Overall Length Examples: ~44.5 mm for a 24CT62S #4 nozzle in coarse thread 16 mm bore version. Example: 25CT62 nozzle sold as 2.2″ length (~55.9 mm) in some listings.
Ampere Rating / Duty Cycle #4 style, heavy-duty variants, up to around ~400‑450 A depending on wire size and cooling. #5 style versions are rated up to ~550 A in certain specs.
Compatible Contact Tip & Diffuser Series Compatible with 14‑series / #4 tips and diffusers. The nozzle screws over the diffuser/insulator fitting designed for #4 torch front ends. Matches #5 series (25 / 25CT‑series) contact tips & diffusers for #5 torches.

Applications / Use Cases

  • For welding operations requiring strong gas shielding over the weld pool, especially in heavier metal thicknesses and longer welds.

  • For jobs where the nozzle may approach the workpiece (tack welding / stitch), recessed tip designs help prevent nozzle damage.

  • Suitable in MIG / MAG, flux‑cored welding, and other processes needing robust protection of the front‑end of the torch.

Maintenance & Performance Tips

  • Keep the nozzle clean of spatter; internal buildup reduces gas flow and causes turbulence in gas coverage.

  • Match nozzle bore to wire size and required gas flow; wrong size reduces performance or can waste shielding gas.

  • Inspect threads (both coarse thread on nozzle and matching diffuser threads) for damage; poor fit leads to gas leaks or overheating.

  • Use correct nozzle‑to‑tip relationship (flush, recessed, protruding) based on application to avoid arc instability or tip burn back.

Description

Tweco Nozzle – #4 (24CT62) & #5 (25CT62) Series

Product Description

High‑performance MIG welding nozzles engineered for Tweco / WeldSkill style torch #4 and #5 guns. These nozzles are designed to shape and direct the shielding gas flow over the weld, protect the contact tip, manage heat, and influence bead appearance and spatter. The 24CT62 and 25CT62 are coarse‑threaded copper nozzles, compatible with heavier duty welding, built to resist wear and offer reliable gas coverage.

Key Features

  • Material & Construction
    Manufactured from high‑conductivity copper or copper‑alloy (for example, 122 DHP copper), ensuring good heat dissipation and durability.

  • Coarse Threaded / Fixed Style
    The “CT” in 24CT62 / 25CT62 stands for “Coarse Thread,” meaning fixed nozzle thread type that secures over the diffuser / insulator in a consistent fashion.

  • Tip Relationship (Recessed / Flush / Protruding)
    The nozzle tip is “recessed” in many examples (especially 25CT62 #5 versions) to allow longer stick‑out, protect tip, reduce chance of spatter contact etc.

  • Easy Identification
    Part number (e.g. “25CT‑62”, “24CT‑62S”) rolled or stamped on outside surface for quick identification.

  • Heat & Duty Capacity
    Suitable for medium‑to heavy duty welding applications. For example, #5 (25CT62) listed for up to ~550 A in some specifications
