A multi-process welder is a versatile welding machine that is capable of performing different welding processes like mig, stick, tig and flux core welding. On the other hand, A single-process welder is a welding machine designed to perform only one specific welding process. For example, only mig or flux core or tig welding.
Now are you stuck between choosing between a multi process welder vs single process welder?
Let’s find that out through a little bit of comparison between the two welder types. You will know which one suits your needs the most.
So, here we go–
All About A Multi Process Welder
A multi-process welder is a single welding machine that can perform multiple types of welding processes. It can be 2 in 1, 3 in 1 or even 5 in 1 welding machine. It may contain Tig, Lift Tig, Mig, Stick, plasma cutter and flux core welding facilities within a single machine. All you have to do is switch between modes to get your desired welding type by pressing a button on the welder.
When you should use Multi Function welder
In the following cases, a multi-process machine is much more preferable to a single-process welder.
- Welding Different Metals: Whenever you have different types of metals to work with, you should use a multi function welder. The reason is different metal types react differently with certain welding techniques. For example, Tig welding brings better results on projects like welding aluminum, while for welding stainless steel MIG welding get good results. So, when working with different metal types, it’s better to have a multi working welder. This opens up the option to get the best results.
- Different Thickness: When you are working with different metal thicknesses. For example, TIG welding works much better than MIG welding for thinner sheets of metal. Conversely, MIG works better for thicker materials. So, having a multi-tasking welder with MIG and TIG welding facility gives you the option to work with different thicknesses.
- For Better Results: Each welding process has its unique welding results. When your project needs different welding joints, a multi-process welder makes more sense than a single-process welder.
- For Flexibility: If you have to weld both indoor and outdoor, then a multi process machine is a better choice. Because you can’t undertake all kinds of welding projects outdoors using a single welding technique. For example, for outside work stick welding is better option. And for indoor both mig and tig are the best. So if you choose multi process machines, you can switch the welding process while working outdoor or indoor. It gives you a flexibility that not single process can provide..
All About A Single Process Welder
Single process welder is a dedicated welder machine performing only one type of welding process. This means you can do only TIG welding if you have a single process Tig welder and mig welding when you purchased a mig welder. The option here for you is limited in terms of welding processes.
When You should use Single Process Welder
Now, it’s time to take you through when it’s not preferable to go for a single-process welder.
- Best Quality: A single-process welder gives you better quality, performance, and power for your welding. For different projects, different welder features are required. For example, the projects where seamless welding is required, tig welding would do the best job. And projects that are undertaken outside at dirty atmosphere, stick welder would cast a great result.
- For Similar Projects: In case of working on one material, one thickness, and as ingle welding joint at a time, a single process welder is a better choice. The overall result is way better than a multi process welder.
- For Bigger Projects: For industrial works or bigger projects you should use single process welder as single process welder provides more strength and ductility in welding which you need in big projects.
- For Plenty Of Power: Projects where more power is required, single process would be better choice for them. For example, if you are planning to perform welding on bridge construction, building construction or underwater projects, one specific type of welding process must be selected and a single process welder machine is required to use in this case.
Multi Process Welder vs Single Process Welder (Differences)
Here are some factors that create the difference between these two types of welders-
Welding purpose, Features & Functionality
- The welding purpose of a multi-process welder is to use different materials and thicknesses in a single project. It contains digital display and guide the welder to choose correct amperage and welding voltage.
- While the single process gives you quality welding with great power and accuracy. Also, single-process welders are much more professional, while multi-process welders are better for DIYs. Single process machines also have digital display but the range is little lower than multi process.
Welding Strength & Capacity
- In terms of welding strength and capacity, single-process welders have the upper hand over multi-process welders. As they are focused on one particular type, all the energy is utilized to its full potential resulting in a better weld and finishing more worth than multi-process.
Frequency & Control
- Multi Function welders are a better option for beginners due to their good frequency and great control. However, experienced welders can easily use the machine as they are familiar with every tricks and tips of different welding techniques.
- While the single process is better for professionals as they require some expertise and experience.
Quality of Welds
- The choice between a single-process welder and a multi-tasking welder in terms of ensuring the best quality result depends on several factors, and there is no one-size-fits-all answer. The suitability of each type of welder depends on the specific welding application, the skill level of the operator, and the requirements of the project. Overall, both welders are suitable for producing best quality welds.
Weight and Usability
- Multi-process welders are better in this factor. The usability is obvious; you can get different welding types in a single machine. As for the weight, they are usually lightweight and convenient to use compared to single-process welders.
Skill Level
- Operating a multi process welder generally requires a higher skill level compared to a single-process welder. This is because the welder needs to be proficient in multiple welding processes, each with its own set of parameters and techniques. The ability to switch between processes seamlessly requires a good understanding of the characteristics of each welding method.
- Operating a single-process welder is generally more straightforward as it is dedicated to a specific welding process. The required skill level is often lower, making it suitable for beginners or those specializing in a particular type of welding. Welders using single-process machines can focus on mastering the nuances of the specific welding process they are working with.
Future Expansion
- Multi-process welders are designed to handle different welding processes, which can be advantageous as new welding technologies emerge. Some advanced multi-process welders come with software interfaces that can be updated to accommodate new welding technologies or improvements.
- Single-process welders are often designed with a specific welding process in mind, leading to optimal performance for that process. However, if a significant shift occurs in welding technology, replacing a single-process welder with a new machine designed for the emerging technology may be necessary.
Current & Electricity Efficiency
- On a single process welder, you get a single current output. It’s either DC or AC.
- For a multi-process welder, you get both AC and DC functionality. So, single process is more electricity efficient than multi.
Shielded Gas
- This factor doesn’t have an impact on the multi-process welder or single-process welder. It would help if you still had different types of gases for different types of welding processes. You can’t do all TIG welding with the same shielding gas you use for MIG welding, even with the multi-process features.
Safety
- Multi-process welders tend to be much safer than Single process welders because of their ease of usage. You don’t need to go through a lot to set them up or do the work.
Cost
- From the perspective of price range multi process machines worth it. It offers different types of welding features within a single machine and comparatively at a reasonable price. Some multi-process comes up with plasma arc welding also saving money for seasonal welders though there are controversies about their functionality.
- Single process welder on the other hand is more expensive welder in the sense of having room for going in different welding processes. You will need to buy more than one welder for different need and also single process welders because of their quality and functionality costs more that multi-process sometimes.
Conclusion
Now, as you can see, the difference here is obvious between the two welders. That’s not the problem at all. The problem arises when you try to consider which one to buy. In my opinion, if you are getting a welder for DIY (do it yourself) projects, then multi-process welders are great options for you. But if you want to go professional, then single-process welders are better choices.
