OVERVIEW

Upgrade Your MIG Gun with Tweco Velocity VNH75F

Keep your welds clean and your arc stable with the Tweco Velocity VNH75F MIG nozzle. This pack of two heavy-duty nozzles is built for welders who demand reliability and performance from their equipment. If you are running a Tweco Spray Master, Fusion, or any MIG gun converted to the Velocity consumable system, these nozzles are the genuine replacement parts you need to maintain peak efficiency.

The VNH75F is a workhorse nozzle. The "75" stands for a massive 3/4-inch bore opening, which is ideal for high-heat applications. Whether you are pushing heavy flux-cored wire or running solid wire in spray transfer, this wide bore ensures your shielding gas completely envelopes the weld puddle, preventing porosity and ensuring a high-quality bead. The "F" stands for Flush, meaning your contact tip sits perfectly level with the end of the nozzle. This is a favorite setup for many professional welders because it allows you to get close to the joint for tight control without accidentally arcing the tip against the metal, while still letting you see exactly where you are welding.

One of the biggest frustrations in welding is dealing with spatter buildup and seized parts. The Tweco Velocity system solves this with its innovative design. These nozzles don't rely on fine threads that get clogged with grit. Instead, they seat firmly and conduct heat backward, away from the puddle. This keeps the nozzle cooler, meaning spatter doesn't stick as hard and is easier to clean off. Less time banging your gun against the table means more time burning wire. Grab this 2-pack today and ensure you have the spares you need to finish the job.

Why Choose Velocity Nozzles?

  • Cooler Operation: Superior heat dissipation keeps the nozzle from overheating.
  • Easy Cleaning: Spatter removes easily from the cool-running copper.
  • Secure Fit: No threads to strip or seize during changeouts.

FAQ

VNH stands for Velocity Nozzle Heavy-Duty. 75 refers to the 0.750-inch (3/4") bore size. F indicates a Flush contact tip relationship.

Yes, provided your Spray Master gun is equipped with the Velocity series conductor tube or conversion kit. It fits all Tweco guns set up for Velocity consumables.

This product (SKU 1240-1876) contains a package of 2 nozzles.

A flush nozzle offers a good balance between gas coverage and visibility. It allows the welder to maintain a proper stick-out distance while still being able to see the arc and puddle clearly.

No, the Velocity system uses a specific engagement method that is different from traditional fine threads. It is designed for quick removal and better thermal conductivity.

Yes, specifically for Gas-Shielded Flux Cored welding (Dual Shield). The large 3/4" bore is excellent for the high gas flow rates often required in these applications.

VNH indicates 'Heavy Duty' with thicker walls for higher heat applications, while VNS indicates 'Standard' duty for general purpose welding.

The Velocity nozzle design typically integrates the insulation and seating required for the system. Always check your specific gun manual, but generally, the Velocity nozzle is a direct replacement part.
