Mig welding nozzles by SUPERIOR CONSUMABLES are the only WISE CHOICE for your tough welding applications. That’s because they offer the same high performance as original equipment consumables.
SUPERIOR CONSUMABLES deliver the performance and reliability you need to minimize your production costs while maximizing welding efficiencies!
Our mig nozzles are precision machined to stringent standards for excellent fit and long life.
Our welding nozzles are available in many popular brands of self insulated, standard and heavy duty in a wide variety of sizes for most every Robot and manual welding application.
Selecting the Right Shape of MIG Welding Nozzle
There are several shapes of MIG welding nozzles available, including straight, bottleneck and short or long taper nozzles. Straight nozzles typically have larger inside diameters but don’t offer as good of joint access. If greater joint access is critical, bottleneck nozzles, which are particularly good for automated welding applications, are a better option.
Short and long taper nozzles are also common choices for gaining good joint access. Note, that long taper nozzles may collect spatter more easily due to a smaller inside diameter. Short taper nozzle can help prevent such a problem.
When selecting a nozzle, finding one that provides the best joint access for the application is most important. It is also imperative to avoid contaminants from affecting the gas flow to the weld puddle. The best choice is to use as large of a nozzle as possible that still allows access to the weld joint. Doing so helps ensure the greatest shielding gas flow. Larger nozzles are also less prone to collecting spatter compared to those with smaller inside diameters.
Selecting the Best Material
Heavy-duty nozzles have thicker walls, as well as thicker insulators, and are designed for use in applications ranging from 400 to 600 amps. Due to their heavier construction, these nozzles resist heat better than standard varieties. Standard nozzles tend to have a thinner wall and are better for 100- to 300-amp applications. Slip-on nozzles are quite prevalent in the industry, compared to thread-on nozzles that need to be twisted to install, and they offer the advantage of being able to change over more quickly.
Nozzles are typically available in brass or copper. Brass nozzles tend to resist spatter well and are good for lower-amperage applications (100 to 300 amps), whereas copper nozzles are better for high-amperage applications (above 300 amps) or for those with longer arc-on time.
For high-amperage water-cooled applications, there are also nozzles available that circulate coolant around the nozzles.
Proper Storage, Handling and Maintenance
It is important to handle, store and maintain nozzles properly to gain consistent welding performance and prevent premature failure.
Look for nozzles that are engineered with a smooth surface finish and edges, as these resist spatter build-up. Heavier nozzles are also more desirable than thinner ones since they tend to resist heat better. Consider purchasing nozzles that feature a brass insert as it helps the nozzle maintain its inner diameter, and prevents the nozzle from rocking and wearing prematurely. The addition of a high-temperature fiberglass insulator can also help extend nozzle life. Heavy-duty crimping on the nozzle holds the layers together and is an indication that the nozzle has been built for longevity.
Storing nozzles in a bin, rather than the original packaging, can lead to scratches or dents that allow spatter to adhere and will ultimately shorten the life of the nozzle. Use gloves when handling nozzles or replacing nozzles to prevent dirt, oil or other contaminants from adhering to them and inadvertently entering the weld puddle.
As with any front-end consumable, nozzles play an important role in maintaining good weld quality and can impact productivity and costs. Careful selection and maintenance can minimize downtime and keep your welding operation running more smoothly in the long run.

Many self proclaimed ORIGINAL manufacturers contract out a large percentage of their consumable manufacturing needs and just charge a higher price for their logo and packaging. Some even go as far to make statements that the warranty is not valid if their Original brand consumables are not used. The WISE purchaser knows that these statements are false and misleading and are contravening to the MAGNUSON MOSS act in the USA and against the COMPETITION ACT in Canada.
