A MIG gun liner is an important consumable because it can make a significant difference in gun performance and the time and money an operation spends in unplanned downtime. Proper installation of the liner is critical to its ability to guide the wire through the welding cable and up to the contact tip.
Improper liner installation — which includes trimming the liner too short or having a liner that is too long — can result in a number of problems, such as birdnesting, wire feeding issues and increased debris in the liner. These issues can result in costly rework and operator downtime for maintenance and repairs, which impacts productivity. Also, wasted wire due to issues like birdnesting can drive up costs for a company.
The installation process is somewhat similar for all types of MIG gun liners, with some variations. Here are some general steps to consider when installing a new MIG gun liner.
There are some variances in the installation process, depending on the type of liner being used. Here are some differences to note:
Installing a front-loading liner
Follow these steps when installing a front-loading liner.
Installing a front-loading liner with the spring-loaded module
The only difference in this installation process is that there is no receiver in the back of the power pin. The receiver is built into the module pin.

Retrofitting a gun
The installation process also varies when retrofitting a gun from a conventional liner to a front-loading liner. Here are a few additional things to remember:
Proper liner installation can help optimize performance
The quality of the liner also can impact welding performance, productivity and operator downtime, so it’s important to buy quality liners from a trusted manufacturer. Choosing the correct size of liner for the wire being used is another way to help maximize performance.
While liners may seem like a small part of the welding operation, it’s important to be mindful of the impact they can have on quality, performance and costs. Liners perform a vital function in the MIG welding process, and the proper installation and maintenance of liners can help reduce costly rework, operator downtime and wasted wire.
