Many people find it a bit challenging to clean a Mig liner as they don’t know the complete working mechanism of this element. However, cleaning a MIG welder liner is a more straightforward job.
How To Clean Mig Liner
You only need to follow a few steps.
- Disassemble your welding torch Liner by losing the liner nut. Consider removing the gas diffuser, nozzle, and the weld tip. Now remove the mig wire from the liner.
- Examine the welding gun and try removing the liner from it.
- You may encounter debris or dust in the lead; use air pressure to remove them.
- Make sure that the liner has a constant flow without any bending. If it is bent, consider replacing it with a new one.
- Return to installing the liner into the welding gun and your job is done.
Why Mig Liners Get Dirty and How?
Lack of maintenance is the most common reason a MIG liner gets dirty. If you don’t care to correctly clean your machine from time to time, dirt may deposit into your gun liner.
If you do not keep your liners clean often, chances are you see more dirt on them. It can lead you to some serious and costly failures.
Primarily, the liners are designed to balance rigidity and flexibility. So, if you abuse the line and cable, it might cause problems with that wire liner. Extreme bending leads to poor wire feeding and reduces the lifespan of wire spools.
Some small metal fragments and dust particles may keep piling up when a spool of wire is bent. Ultimately, these will cause your wire liner to get dirty.
In Contrast, when you install the liners incorrectly during replacement, it will also cause a liner to get dirty quickly.
Moreover, everything gets dirty if it remains unclean for a longer period of time. So regular checking and cleaning is a crucial job for any parts of a mig welder including mig gun liner.
How To Prevent Dirt In The Liner?
You must clean gun liners thoroughly to get the most out of your welding. But how do you prevent that dirt in the liner?
1. Have Little Pads
There is a way that you can use some nice little pads that work like a clip right on the welding wire. These pads keep all dirt and debris away from the liner and don’t let them gather up there.
2. Ensure That You Are Not kinking Your Roll of Wire
Second and most important, never bend or disturb your welding wire. Because doing so will cause your welding machine to slow down. Bending will cause all sorts of tiny debris to build up into the liner blocking its way for the efficient welding process.
In that case, the harm will be higher, and you’ll have to replace the liner with a new one. So, keeping it straight will cause fewer problems to deal with.
3. Keep It Clean On Regular Basis
Taking reasonable and proper care of your welding liner weekly will not hurt the liner itself.
Make sure you clean the liner very often so that wire feed operates effortlessly. In that way, you can expect more extended life from your liner.
4. Ensure the Proper Installation After Cleaning Or Replacement
As studied earlier, the improper installation and repairing of the liner can cause debris to build up.
In that case, you should always be more careful while replacing or installing the liner after cleaning it up. Don’t rush, be calm and do things smoothly.
That’s how you can prevent that liner from getting dirty by following all these steps or taking these precautions.
Why does Mig Welding Need Mig Liner?
The importance of a Mig Liner in this type of welding is enormous. This liner helps the welding wire to easily transfer from one point to another in a gun cable. Here one point is the wire feeder or drive roll and the other is the contact tip of mig gun.
- A liner is a water-resistance sleeve for me. The extensive liner protects the sprayer from the heat of the wire while welding.
- It protects your hands from heat. And it saves sharp edges on the sprayer that would have been cut during installation and removal.
- In addition, the MIG liner helps stabilize arc weld puddles and protects electrode wire from contamination resulting in reduced spatter and slag issues. Its purpose is to make your work safer, easier, and more efficient.
- If the liner gets disturbed, it will hamper your welding process eventually, and you will end up having a stopped apparatus.
When Should I Replace Liners?
The replacement of an old liner with a new liner becomes important when you don’t get an efficient mig weld. When you see that the liner has been clogged due to an amount of dust and debris, and there is no way to clean it, you should replace it with a new one.
However, it also depends on how you use a liner and maintain it. If you use it regularly, you may need to clean a liner once a week. And this practice will save you extra bucks you would spend otherwise on a new liner.
Besides, don’t let the liner bend while you are working. Because bending will block the flow of electricity, and eventually hamper the wire and the gun.
Last Words
Where Mig Welding is a highly popular and widely used welding process, the importance of a liner in the mig machine is enormous. Without the presence of a fine liner, you cannot complete a project successfully.
But things will only stay in your favor if you get a clean liner for the work. If you won’t, you will have to spend more bucks every time the welding process gets stopped. Hence, the decision is yours.
