Flux core and MIG welder are a bit different in characteristics. The MIG wire is solid, and the flux core wire is like a hollow tube. Therefore, can you use MIG wire in a flux core welder? What will happen then?
You can use the MIG wire in a flux core welder. But the gas needs to be available in the system. For that, you need to moderate your flux core welder to create a way to shield gas. Check out the MIG wire pull-out speed and adjust the pressure. And don’t forget to change the polarity before starting welding.
If you can make the moderations with proper guidelines, you can use MIG wires in a flux core welder.
MIG Welding Wire Vs. Flux Core Welding Wire
Metal Inert Gas (MIG) welding wire and Flux Core welding wire are popular choices in the welding field, each with advantages and applications. A MIG welder mainly uses a solid wire to weld on any metallic surface. On the other hand, a flux core welder uses a hollow tube wire to weld.
You would need a tank of shielding gas as feed in the torch that helps move the wire during welding. The flux core welder also needs shielding gas, but it will flow inside the hollow space of the wire. That also produces a productive gas during welding.
MIG Wires in the Flux Core Welder
Despite their structural dissimilarities, you can use MIG wires in the flux core welder. But first, you should know the flux core welding wire types: self-shielded and gas-shielded.
The gas-shielded flux welders need external shielding gas to help the wire move and increase the welding rate. However, the self-shielded flux core welders don’t need shielding gases to assist in the wires’ pathway. They mainly use gasless flux core welding wires.
Therefore, if you want to use MIG wires in such flux cores, you need conversion kits to help create separate gas lines at the gun’s or torch’s end.
And also, be aware of the polarity. Otherwise, there will be more splatters than necessary, and the attachment won’t have enough strength to hold onto the surface.
When Can You Use MIG Wire in A Flux Welder?
It’s not usual to use MIG wires in a flux welder. Even though you are in the middle of welding, you can’t remove the flux wire and attach a MIG wire to the weld.
You can take such measures when you have no alternate options, like running out of flux wires, an unused flux welder, a surface that needs to be welded with MIG wires, etc. But before that, learn MIG welding wire types to avoid unsuccessful outcomes.
Even when you ought to buy a welding machine rather than using your old flux core welder, you can modify your old one with some conversion kits and make it suitable.
How To Use MIG Wire in A Flux Welder?
Suppose you have decided to use MIG wires in your flux core welder. But how should you proceed? Well, here’s what to do:
Step 1: Remove Unnecessary Parts
Due to structural differences, you don’t need all the parts of a flux welder while converting it into a MIG welder.
If possible, get an electronic solenoid valve to adjust gas flow while welding.
Step 2: Assemble the Circuit
How do you actuate the valve simultaneously when the welder feeds the wire? Well, you need to develop the circuit.
Therefore, use a cooling fan connected to the relay and solenoid valve. The control loop helps move the wire forward and pass the gas flow accordingly.
Step 3: Attach the Way of Shielding Gas
Now, it’s time to make a pathway for shielding gas.
For that, rob the gas shield valve at 90 degrees and attach the gas nozzle with an elbow (45 degrees). The hose should start from the solenoid to the end of the whip onto the elbow.
Step 4: Test the Welding
All the settings are done, and now you have to test the welding. The result may satisfy you, but melted metal’s holding capacity is nearly zero.
But why? Just because of the polarity. You won’t see any penetration over the metal surface after the welding.
Step 5: Check Out the Polarity
So, when switching from flux welding to MIG welding with shielded wire, you must swap the polarity. Make the electrode positive and the ground harmful as you are using DC.
Step 6: Adjust the Power and Final Test
After that, test the welding again and adjust the power according to your demand. You can use welding on the actual surface when the calibration is complete.
Is It Worth Using MIG Wire in A Flux Welder?
You might think all these efforts, time, and money on the MIG wires on a flux welder are worth it. We would say it depends on your conversion kits.
It may not be worth it if you need to buy all the conversion kits. That’s because you can get a MIG welder for the same price as this flux core welder (even though we are keeping the extra costs aside).
On top of that, the dual shield flux core wire can handle better penetration in the thick walls.
