There are some common problems in MIG welding that sometimes it may not start. Then, it also can be that you have switched on the machine and then suddenly fuse it.
In this regard, you have to know about Lincoln Mig welder troubleshooting. You know all types of welding processes have their own complications and problems. However, MIG is not different from it. These common problems can hamper and slow down the whole process. But you should do something and not slow down the process, right?
Hence, in this situation, you can apply your skill to get the solution of the MIG welding process. In this article, you will know the facts of MIG and how to solve these from top to bottom!
So, let’s go ahead.

What are the most common problems with MIG welds?
Some common problems with MIG weld are
MIG produces excessive spatter. This is a very common problem in MIG welding.
The polarity switch doesn’t work:
When the welder is under load, the Lincoln MIG welder tries to warn you by stopping working. Insufficient gas coverage is the main culprit of this problem.
Sudden electric shocks happen in MIG welding. This problem happens when the welding machine’s frame is not properly grounded.
Bad ground clamp
Bad ground clamps can lead to the malfunction of the welding machine. When the high resistance happens due to mistransports of the flow of the current.
Improper weld bead problem
This problem happens when inadequate heat is input by the welders.
Lack of fusion
In the transfer process of ar,c cold lapping is actually the main problem of creating the lack of fusion problem.
How do you troubleshoot a MIG welder?
Well, if there is a problem, then, of course, there is a solution too!
As a welder, you have to know the solution to the common problem. You can solve the very common problem as well as the advanced problem by yourself.
When porosity comes from the imperfect surface condition, you can use the remedy for the uncleaned, imperfect, and contaminated surface to clean it. First, you have to ensure the weld joint and then, the unlaminated workpiece.
The air bubble of the weld joint can hamper the welding process and the laminated workpiece leads to poor-quality welding.
However, if you face the problem of improper weld bead problem, then you should be careful about the correct amperage according to the thickness of the material. By hearing the arc sounds, you can easily understand the correct amperage of the current.
However, most of the problems you can solve by yourself if you know the techniques to solve them. Anyways, another question frequently asked is how to fix a Lincoln MIG welder that ‘stutters’. In this section, you will get the answer to this question too.
How to Fix a Lincoln MIG Welder That ‘stutters’
Welding is a complex process and if any problem like stuttering occurs, then the problem can create so much hassle. There are some common causes for that MIG welding to start misbehaving and creating stutter problems. Such as-
- Poor conductivity or excessive resistance
- Dirty welding components
- Low level of gas flow
- Worn contact liners and tips, etc.
However, you can control the problem of stutters and take precautions so that this problem never happens. Equipment management is an important thing to avoid this problem.
Anyways to solve the problem of stutters, you should have concerned about some of the facts:
You should always start working on this problem after the welder is unplugged. As it can be dangerous to work with electronic devices, you should unplug them before working on them.
Open up the handle
Sometimes the problem of assembly of the trigger in the handle of the MIG welder can cause the problem of sputters. In this problem, you have to remove the handle to clean it. You need to remove the collars which are at the top and the bottom of the handle.
Inspect the inside of the gun
The problem with the gun trigger can happen due to the problem with the small pushing copper ring against the circuit of the gun. Normally a plastic lot is placed in between the copper ring and the circuit to reduce the alignment of these two.
If this plastic slot is not seated properly, then the problem is raised. So you can solve this problem by pushing the plastic slot correctly into place. You can add glue or something which can strongly hold this little thing properly.
Reseat and trigger
After successful reseating, you can practice the trigger of the gun. If everything is aligned properly along with the compression of the spring, then almost your gun is ready to serve properly. This is a little bit tricky to hold the trigger of the gun.
Now the gun is ready and you can test it by practicing some work through it. You can take some scrap pieces and metal to test it.
Perhaps, you can also prevent the problem of stutters by doing maintenance of the current flow and checking the voltage. Then the equipment always needs to be cleared and cleaned. Turn off the plug and gas machine after finishing your work. Little maintenance can keep your machine a long time problem free.
How do you reset a MIG welder?
To avoid the very complex problem of MIG welders, you can also reset the whole functional system of MIG tools. Especially when the operating system creates a problem you have to reset it.
When you are not able to know the reason why the machine performs incorrectly and uncharacteristically, a reset can clear and set up this issue.
By going through the time menu, you have to go to the button of “power off”. Then turn off the power button to shut down the machine. After that, you have to turn it on by pressing the power on the button which is located on the front of the machine.
You need to rotate the power voltage knob counter clockwise until the “res” is displayed on the left meter. And in the right meter, it is displayed as “off”. Then, you have to turn the right knob clockwise until the “on” is displayed.
Now, the machine is successfully reset and the gun trigger is also ready to work by default setting.
