Wondering how to convert gas Mig welder to gasless?
A lot of people wish to purchase a gasless Mig welder after purchasing a gas Mig welder. But you don’t need to buy another Mig welder when you know how to convert it to gasless.
A gasless Mig welder has multiple advantages: it is portable, lightweight, and faster than stick welding. Here we will guide you to learn the perfect way of transforming your gas Mig welder to gasless.

What Is The Difference Between Gas Mig and Gasless Mig Welding
A noticeable difference exists between gas and gasless Mig welding machine. A gas Mig welder has different polarity settings from a gasless Mig welder.
For example, a gas Mig welder features a positive (+), single torch feed, while the other one has a negative (-) torch feed.
Another noticeable difference is its fumes. A huge volume of smoke and fume production occurs from a gasless Mig welder, while the other one only produces a tiny portion or nothing at all.
Gasless Mig welders are more appropriate for outdoor ventilated areas, while gas Mig welders appear perfect for indoor areas. You have to spend more time cleaning and preparing the metal for gas Mig welders than gasless Mig welders.
Can You Really Convert Gas Mig Welder to Gas Less
Though it is a little bit tricky to convert a gas Mig welder into gasless, you can do it if you are electrically minded.
It generally requires you to exchange the output cables with gasless cables from the internal part of the welder where the rectifier is located.
However, it is initially crucial to determine whether it is compatible to convert or not. Some gas Mig welders have fixed construction that can’t be converted.
How Can You Convert Gas Mig Welder to Gasless Mig Welder
Converting a gas Mig welder to a gasless Mig welder requires you to follow some necessary steps. Here are they:
- Step: 1 — Cleaning the Metal
Before converting your gas Mig welder into a gasless Mig welder, you want to clean the metal part properly to make the task easier. Just use an old brush to get rid of dirty metals, sand, and debris from its surface.
- Step: 2 —Adjusting the Setting of the Gas Mig Welder
Now, you want to select the level of the ideal amp you will need for completing your particular project. Since almost all Gas Mig welder come with a control panel, adjusting these settings are easy-going.
You need to change the settings as per the material you prefer for welding. In addition, considering the metal thickness level is also important.
- Step: 3 —Switching On the Machine
After inserting the wire in both power sources and the machine, carefully turn on the machine. Going through the instruction manual will you a decent idea to learn the perfect way of wire loading.
- Step: 4 —Selecting Current Strength
The next task is determining and selecting the appropriate strength of the current. The higher the current level you choose, the more powerful it will be.
Generally, you want to select a considerable amount of current if the metal is pretty thick. Compared to aluminum, steel & chromoly welding needs a higher level of current.
- Step: 5 —Choosing the Wire Feed
You want to select the ideal speed for your wire feed at this step. Adjusting the wire feed to the correct level requires considering the type of project you will handle and the metal type.
Generally, a specific gear is essential to install for manual wire feed. But if your welding machine has an automatic feed, you don’t need to install additional gear.
- Step: 6 —Changing the Polarity
Here comes the most important part. The gas welder features two leads that have a direct connection with the posts.
Changing their polarity will be necessary if you replace the wire. Generally, you want to swap the output cable at the rectifier from the internal part of the welder.
- Step: 7 —Finishing Up
Now, your gas welding machine is converted into a gasless welder machine. You can now test it using an unnecessary metal part.
Safety Measures To Maintain In Converting Process
Since you are working with electrical items, ensuring optimal safety is crucial to avoid facing any hazardous situation.
Generally, gas Mig welders can cause product fumes and excessive flushing lights while working on them.
So, don’t forget to wear a decent pair of high-quality protective gloves and a welding helmet to keep yourself out of danger.
Besides, you should be continuous while touching different wires and make sure you have adequate knowledge on which wires are connected to which one.
Can You Convert Gasless Mig To Gas Mig
Yes, you can convert your gasless Mig welder into Gas Mig by following the opposite approach.
But you need to maintain the ideal level of voltage and heat constantly. In addition, choosing the right wire is also important to provide appropriate current strength.
Plus, you need to use filler metals to prevent porosity issues. Don’t forget to clean the welding material between passes and maintain the right penetration.
Which One Is Good For Perfect Weld?
Though both options are good, their requirements will vary from each other. Here are all the main reasons behind choosing a particular one.
- Your Job Location
When you are working outside areas like your firm house or any rural areas, choosing the gasless Mig welder is better.
But working in any internal area requires choosing the gas Mig welder for extra safety.
- Type Of Metal
Gasless Mig welders are a little bit risky to work for some metal objects. For example, if you are welding stainless metals or aluminum, it is best to use a gas Mig welder to ensure optimal safety.
- Portability
Since using a gas-shielded Mig requires you to carry the gas cylinder where you want to wield, you should be preparing yourself for that.
If it is pretty hard to move the gas cylinder from one spot to another, you should use a gasless Mig welder.
- Cost
Compared to gas Mig welder, gasless Mig welders are a little expensive since you have to use a gas cylinder in addition to a wire spool.
Conclusion
When it comes to choosing a welder, we often feel confused about whether to choose a gas or gasless version. Since professional people handle a wide range of projects, they will need both types of welders as per the work type.
Knowing how to convert gas Mig welder to gasless can help you utilize one type of welder for another. However, the procedure may appear a little bit tricky if you don’t have enough electrical knowledge.
We have already outlined the perfect way to easily modify your gas Mig welder to gasless. Make sure to follow it carefully.
