Like other consumables, MIG welding contact tips are available in a range of materials and sizes. The difference between an efficient job and one beset by problems can be seen by choosing the right tip for your application.

Are all contact tips the same?
Contact tips come in a range of sizes. Selecting the correct contact tip for the job is important because you want to create optimal conditions in which the wire feeds into the connector. For example, if you’re working with a connector that has a diameter of 1/4″ or less, you’ll want a wire that’s at least 3/8″ in diameter.
If you need to work with connectors that have a larger diameter, such as 1-1/2″ and 3-7/16″, you can use a thicker wire, but be aware that it will be more difficult to get a good contact with it.
Are all MIG nozzles the same?
The types of MIG welding nozzles on the market are available in a range of sizes and shapes. Depending on what the application is, the welding process that is being used and joint access, you should choose one. It’s possible to get nozzles in slip-on or thread-on varieties, as well as heavy-duty or semi- heavy duty versions. This is the most common type of nozzle used for welding.
It is threaded on both ends, allowing you to attach the nozzle to the joint. Thread-ons can be used on a variety of materials, including metal, plastic, rubber, fiberglass, glass, wood and more. They are also available with or without a spacer, which is a small piece of metal or plastic that helps hold the threads in place.
The threads can also be welded to other surfaces, such as the face of a pipe or the underside of an object, to make it easier to work with the material. For example, a threaded nozzle is more durable than a non-threaded nozzle, but it is also more difficult to clean and maintain.

Are MIG liners universal?
Available in lengths of up to 25 feet, Universal Conventional Liners are compatible with all Legacy Bernard™ Q-Gun™, S-Gun™ and T-Gun™ MIG Guns and all BTB MIG Guns which have been modified to accept them.
How do I choose a MIG nozzle?
Whatever welding nozzle shape you decide on, use the largest bore size possible for your application without compromising accessibility to the weld joint. This will help you maximize your gas coverage and reduce the chance of spatter build up.
For example, if you are using a 3/8″ diameter nozzle, you will need to use a 1/2″ bore to get the same amount of gas into the joint as you would with a 5/16″ nozzle. If you want to be able to weld with the smallest diameter possible, then you’ll need a 2/3″ or larger bore.
How do I choose a welding tip?
Selecting the right material and bore size In most cases, using a contact tip that matches the size of the wire leads to the best results. An undersized contact tip may not be able to penetrate all the way through the material when wire is fed from a drum or solid wire.
In this case, it may be necessary to use a larger diameter wire to achieve the same amount of penetration. For example, if you are feeding a 500-pound drum of wire through a 1/2-inch-diameter bore, you will need a wire diameter of at least 3/8 inch. If you feed a 2-foot-long drum through an inch-and-a-half-thick material, the diameter will be 1-1/4 inches.
What do the numbers on the welding tips mean?
The tip size number indicates the orifice size and the relative gas rate the tip is capable of producing. The torch tip size is indicated by the number. Torch tip diameter is the diameter of the flame tip, measured in millimeters (mm). This number is used to determine the amount of flame that can be produced by a given size of torch.
For example, a 1.5 mm diameter torch can produce a flame of approximately 0.25 mm in diameter, while a 2.0 mm torch will produce the same flame size. The flame diameter can also be used as an indication of how much heat the torch is able to produce. A torch with a larger diameter flame will burn hotter and produce more heat than a torch of a smaller diameter.
