Why is Mig Welder Liner Important?

Hands down, the MIG wire liner is as essential as basic parts of the MIG welder. It plays a significant role in guiding the wire from the feeder via gun cable to the contact tip. And the contact tip is the part of the mig gun that comes to direct contact with the base metal and work piece.

So if your MIG liner performs poorly, then the gun will eventually turn valueless and produce the worst results. That’s why it is considered a vital part of a mig welding machine.

What To Consider Before Buying Mig Liner (Buying Guide)

When purchasing a MIG gun liner, several factors should be considered to ensure you choose the right liner. Here’s are the factors-


Ensure that the MIG gun liner is compatible with your specific mig gun model. Different manufacturers and models may have variations in liner specifications.

Also verify that the liner is suitable for the diameter of the welding wire you intend to use. The liner should match the wire size recommended for your welding application.

a) Material

MIG gun liners are commonly made from materials like steel or plastics. Ensure the material’s durability especially if you expect to do heavy duty work with abrasive materials.

b) Liner Types

In general, there are several types of liners available around the world. That said, when it comes to the best performance, these are my favorite 3 to go for.

1. Steel Liners for MIG Gun

Steel liners tend to be more rigid, cost-effective, and flexible. Seasoned welders rely on it quite often as they suit mild steel most, including ER70S-6, ER70S-3, and so on.

Generally, a steel liner is abrasive on silicon bronze, aluminum, and such soft wires. Either go for a normal steel liner or the insulated one, depending on your needs and requirements.

2. Plastic Liners for MIG Gun

Apart from the cost-effective “steel liners,” there are also a couple of plastic liners available for your Mig gun. Although every type of plastic liner looks almost alike, they must still be ideal for different projects.

Following are some plastic liners-

  • PTFE (Teflon)
  • PA (Polyamide)
  • C-PTFE (Carbon Teflon)
  • PTFE High-Density (Teflon)

3. Jump Liners for MIG Gun (Neck Liners)

Do you want to enhance your wire liner’s lifespan?

If so, then neck liners are what you might be searching for. They are basically tiny liners with a short collet, which stands in the welding torch.

Using such a liner is convenient, time-saving, as well as cost-saving. And needless to say, it is more ecological than the typical ones.

c) Flexibility

The flexibility of the MIG gun liner is crucial for smooth wire feeding and preventing kinks or bends. A flexible liner is particularly important when working with intricate or tight welding applications.

d) Abrasion Resistance

Consider the liner’s resistance to abrasion, especially if you engage in heavy-duty welding or work with materials that can accelerate wear.

e) Temperature Resistance

Confirm that the liner is temperature resistant. The liner should withstand the heat generated during welding without deforming or compromising its structural integrity.

f) Ease of Installation and Replacement

Choose a MIG gun liner that is easily replaceable. A liner that facilitates straightforward maintenance can save time and effort during routine troubleshooting.

g) Brand Reputation and Quality

Consider the reputation of the brand. Good brands with a track record of producing high-quality welding consumables are more likely to provide reliable and durable MIG gun liners.

h) Cost

Though cost is an important factor, do not compromise the quality of liner. Good things often cost higher than usual. Investing in a high-quality MIG gun liner may initially cost more but can lead to better performance and longevity, ultimately saving you money in the long run.

So go for the best product instead of trying to save money buying a low quality product.

i) User Reviews and Recommendations:

Before buying, always check actual user reviews and seek recommendations from experienced welders.

Mig Welding Liner Problems and How to Solve?

You may notice 2 significant problems in your Mig liner from time to time. And to help you get rid of them, let me show you some of their causes and how to solve them:

1. Problem-1: Erratic Wire Feeding

Such a problem occurs if the liner turns worn out in some specific spots. Moreover, too much dust build-up and improper wire trimming during replacement may also be the common reason behind it.


  • You’ll need to change/replace the completely worn-out liner.
  • Ensure to trim the liner in an accurate way. That mustn’t be too short or too long.

2. Problem-2: Loose Cable Connection

Note that extreme heat build-up and discolored liner are the two common symptoms of electrical short. It happens because of too much loss of electricity at the arc.


  • If the cable gets too discolored due to extreme heat build-up, you’ll need to replace it with a new one.

How to Change Liner and Install New One

Changing liner isn’t rocket science. You only need to follow some few steps to do that, and these are :

  • Unscrewing the nut on the gun is what you need to do first.
  • Pull out the liner right away from your Mig gun. While doing this, there is no need to provide excess pressure out there.
  • Let’s feed the cleaned/newer liner to your MIG gun. Make sure the gun is in a straight direction.
  • Push that liner slowly and as gently as possible. Don’t Rush at all. Now, make a connection between the liner and holding nut and Voila. It’s done.

What Mig Liner To Use for Aluminum Welding

When it comes down to welding aluminum, Teflon stands out as its soft material is highly capable of reducing feed and, at the same time, scratching or scoring wire of the aluminum.

On top of that, it is suitable for high heat projects, which generally use torches (water-cooled) and brass jump liners. Compared to polyethylene, it includes relatively more melting temperature to get your work done.

Talking about the size, it is available in a couple of different choices out there. And the good thing is that a short-sized 3M Teflon MIG Liner is enough for 1 mm to 1.2 mm aluminum wire.

What Mig Liner To Use for Stainless Steel Welding

Indeed, the majority of standard stainless steel wire suits steel liners. Unlike the mainstream liners, they are comparatively more resistant. Plus, they appear to be more abrasive on some of the softer-type wires, such as silicon- bronze, aluminum, cored wire, etc.

Are MIG Gun Liners Universal?

Although welding guns come in different specs and functionalities, MIG gun liners are usually made in a general size to match every gun perfectly.

From the length to the wire’s diameter, everything will appear to be same. But mig liners are not universal.

How to Clean Liner?

Here are the 3 easiest steps for cleaning liner:

  • Step-1: Unfastening Liner Nuts: For this step, get yourself a spanner for unfastening liner nuts. Thus, you’re allowed to remove it from the Mig gun you use.
  • Step-2: Blowing Out the Liner Right Away: Get your hands on a piece of compressed air can or something like that to blow it straight away in bursts via the dirty existing liner. This way, you can cast metal powders away and keep that stuff in a “spick-and-span” condition. 
  • Step-3: Observing the Liner: Let’s notice the liner for kinks when you clean that. Find out whether the weld begins to get too much drag or not. If everything seems okay, then congrats as you’ve cleaned up the liner.

Final Words

The comprehensive guide on MIG welder liner shows you almost all the nooks and crannies you’re searching for to get the most out of it. Plus, I’ve shared my ultimate choices on welder liners.

And depending on your needs and budget, any of them can be your go-to for upcoming projects.
