All You Need to Know About Welding Gun Consumable Components
Welding is surely a complicated skill to master. Not only does it require excellent manual dexterity, but it also requires the welder to be well-trained on different types of equipment, gasses and welding parts that are appropriate for certain types of metal and environments. Welding consumables constitute a crucial part of the welding process. They play an important role in ensuring a strong, clean and high-quality weld joint. There are different types of welding consumables suitable for different welding processes. But before we get to reviewing them, let’s learn what a welding consumable is first.
What Are Welding Consumables?
MIG welding consumables are parts of a MIG welding gun used for sustaining the welding arc and filling the weld joint. Welding consumables require ongoing replacement as they wear with time. Replacing welding consumables is the key to consistent weld seam quality.
Here's What's Included In the Welding Consumable System
The following parts constitute a welding consumable system:
- Nozzle/gas cup
- Contact tip
- Gas Diffuser/retaining head
- Liner
- Power pin (comes with certain MIG guns)
Nozzle/gas cup
The role of a nozzle is to direct the welding gas flow to the weld pool. Nozzles come in different materials, shapes and styles, and choosing the right one can have an impact on the quality of the weld and the overall cost of welding.
Nozzles can be made of brass (good for lower amperage application; resists spatter well), copper (good for higher-amperage applications on 300 Amps and above), and plated copper (is best used with water-cooled MIG guns). Nozzles are also available in different shapes: straight (provide good welding gas flow thanks to its larger inside diameter), tapered (smaller inside diameter), and bottleneck (smaller outside diameter).
Nozzle cups can either slide on or thread onto the gas diffuser. Slip-on nozzles are easier to remove and replace, while thread-on nozzles are more stable as they attach more tightly to the gas diffuser. A two-piece nozzle is another type of connection which comprises a nozzle body and a cone. The advantage of this type of nozzle is that only the cone can be replaced if worn.
Contact tips
The role of a contact tip is to transfer the electric current to the wire as it passes through to create the arc. Contact tips have to be made of durable materials to be able to withstand a high thermal load.
Contact tips are responsible for transferring the welding power to the wire as it passes through to create the arc. This means that its connection with the gas diffuser is critical to ensure good electrical conductivity. A tapered connection is preferred for this reason since it helps to hold the tip securely and accurately in position. The material, size and style of the contact tip also have a role to play in how it performs in any given welding application.
Copper contact tips are the most common and are used in most welding applications. Zirconium contact tips are made for more demanding applications and can last twice as long as copper ones.
Contact tip sizes also play a significant role in welding. Larger outside diameters of contact tips indicate that they can withstand more heat. The inside diameter of the tip is sized to match different welding wire sizes. It is important that the wire matches exactly the inside diameter of the contact tip as contact tips that are too large for the wire will result in an unstable arc, and contact tips that come in contact with the wire will cause too much friction leading to wire feeding issues.
Gas diffuser
The role of a gas diffuser (or retaining head) is to conduct electricity to the contact tip and distribute the shielding gas. They also hold the contact top and nozzle securely on the gun’s neck.
Liners
The role of a liner is to guide the welding wire from the wire feeder through the gun cable to the contact tip. Liners are one of the most important elements of the MIG gun. It is important to choose the right size, type, material and quality of liner to ensure optimized welding performance.
Power pins
Power pins connect wire, weld power and welding gas flow between the welding machine, wire feeder and welding gun. The power pin plays a critical role in determining a welding gun’s compatibility with the welding machine. They are usually made of durable materials so they don’t require frequent replacement. Welders might replace power pins solely to be able to use a single welding gun with different machines.
Many times inexperienced welders choose to work with welding guns that come with factory-installed consumables, or they simply fail to replace important components on time. All this results in poor weld quality and sometimes extra maintenance costs. Spending some time to select, install and maintain welding gun consumables will ensure good weld quality, better productivity and reduced welding machine and welding gun maintenance costs. It is also important to buy welding consumables from a trusted welding supply store, such as Lock 8. Lock 8 offers quality welding equipment and accessories for sale and rent. Clients can purchase equipment online or visit one of our locations in Port Colborne or Stoney Creek, ON. We have a wide range of quality welding equipment for sale and rent.
