Mig Welder Not Feeding Wire? Here’s How to Fix It
MIG welding is a popular welding technique that is used by professionals and hobbyists alike. However, when a MIG welder is not feeding wire, it can be a frustrating and time-consuming problem to fix. Fortunately, there are a few steps you can take to troubleshoot a MIG welder not feeding wire and get it up and running in no time.
Mig Welder Not Feeding Wire: Common Causes
When a MIG welder is not feeding wire, there can be a few different causes. The most common causes of a MIG welder not feeding wire include:
- A clogged or blocked gun liner
- A faulty drive roll
- A worn out contact tip
- A bad wire feed motor
- A bad wire feed control board
It is important to take the time to identify the cause of the problem before attempting to fix it.
How to Troubleshoot a Mig Welder Not Feeding Wire
The first step in troubleshooting a MIG welder not feeding wire is to inspect the gun liner for any blockages or clogs. The gun liner is the plastic tubing that runs from the MIG gun to the wire spool. If there is any debris in the gun liner, it can block the wire from passing through, which will prevent it from being fed. To remove any blockages, use a stiff brush or compressed air to clean out the gun liner.
The next step is to inspect the drive roll. The drive roll is the component that grabs the wire and feeds it through the gun. If the drive roll is worn out or damaged, it will not be able to feed the wire. To inspect the drive roll, remove it from the machine and inspect it for any signs of wear or damage. If it is worn or damaged, it will need to be replaced.
The third step is to inspect the contact tip. The contact tip is the component that the wire passes through before it reaches the workpiece. If the contact tip is worn out or damaged, it will not be able to feed the wire. To inspect the contact tip, remove it from the machine and inspect it for signs of wear or damage. If it is worn or damaged, it will need to be replaced.
The fourth step is to inspect the wire feed motor. The wire feed motor is the component that drives the wire through the gun. If the wire feed motor is not working properly, it will not be able to feed the wire. To inspect the wire feed motor, remove it from the machine and inspect it for signs of wear or damage. If it is worn or damaged, it will need to be replaced.
The fifth step is to inspect the wire feed control board. The wire feed control board is the component that controls the speed and tension of the wire feed. If the wire feed control board is not working properly, it will not be able to feed the wire. To inspect the wire feed control board, remove it from the machine and inspect it for signs of wear or damage. If it is worn or damaged, it will need to be replaced.
Mig Welder Not Feeding Wire: Conclusion
If a MIG welder is not feeding wire, it can be a frustrating and time consuming problem to fix. Fortunately, by following the steps outlined above, you can easily troubleshoot the issue and get your MIG welder up and running in no time. If you have any questions or need additional help, be sure to consult a qualified welding technician.
