Why Choose Multi-Process Welder?

In order to be able to weld various types of metals together and also perform plasma cutting, people have created the best types of Multi-Process welder. There are 3 famous welding combination types nowadays: TIG, MIG, and stick. This type of rig combines these diverse and complex processes allowing users to weld different metals together more easily than any other dedicated welding machine.

Besides plasma cutting, TIG welding enables you to process as much material as possible. A special feature is that most multi-process welding machines only allow DC current, which means they cannot weld MIG aluminum; the multi-process welding machine will be able to improve that.

To help buyers get the best Multi-Process Welder, we would like to recommend the 3 best ones these days:

Buyer’s Guide

What To Consider When Choosing A Multi-Process Welder?

Weight and Portability

If you are seeking the best choice of multi-process welders, it’s safe to assume you’ll be working on a variety of welding jobs. This frequently implies that portability is a factor that you are likely to consider. 

Some multi-process welders are lightweight and easy to carry. You should choose such models if you move around your workshop frequently.  

Main Function

Which welding operations are included is not determined by a single standard. A few welders solely have MIG and stick processes, while others have multiple processes such as TIG, MIG, and flux core as well as a plasma cutter. 

TIG is, without a doubt, the best method for sheet metal. Many sheet metal workers prefer TIG welders operating at less than 5 amps. 

Other processes like MIG and flux core can also work well on sheet metal. However, the condition is that you can easily control the arc and the min output is less than 20 amps. 

Stick arc and MIG processes provide the best penetration when you weld thick steel plate. On the other hand, fabricators can benefit greatly from plasma cutters. 

Main Welding Processes

The welding technology nature allows whatever welding power source to be used to run almost any process. It’s easy to see how high-end machines with many processes and settings differ from cheaper models with 2 processes and basic settings. 

You must decide the processes of welding are of the most importance. To keep prices down, each manufacturer will prioritize a primary welding operation. Make sure that a machine’s primary purpose corresponds to your priorities. 

If you have to do a lot of heavy-duty welding, cut swiftly, and be on the move, then a MIG welder or an arc welder featured a plasma cutter is required. 

If you don’t cut frequently, it can be more cost-effective to obtain a multi-process machine having MIG, TIG, and stick instead of a plasma cutter

Material You Are Working With

The most optimal multi-purpose welder to purchase is influenced by the sort of material that you’ll be welding. It comprises both the metal type and various gauge parts that must be welded. 

With the correct consumables and settings, most premium machines can produce acceptable welds in projects involving steel and stainless steel. Welding aluminum requires more specialization and careful selection compared to generic machine capabilities. 

If you need to weld aluminum using TIG, you’ll have to buy a machine that can work with both AC and DC modes. Aluminum welding benefits from a featuring TIG pulse. 

Duty Cycle

Duty cycles are stated by certain manufacturers whose statement may not be true. 

The duty cycles may not be uniform across the board since you’re working with multiple welding styles. Furthermore, multi-process welders have more output ranges to consider. 

Overload Protection

This is a must-have feature for any welder. Regarding multi-process welders, overload protection is more critical because switching between multiple welding types can strain the machine much more quickly.   

Power Supply

A dual-voltage power supply can make all the difference. Consider how much more freedom you’ll have if you’re not reliant on a single type of energy source. 

For higher output, 220-volt power is needed. This means that you will be able to weld thicker materials quickly. 

Accessories and Options

When comparing prices, keep in mind that if you don’t have a welder with a proper TIG or MIG, these features should be factored in. Certain machines have features such as lift-type arc, high-frequency no-touch arc starts. These features can save you money by slowing down the rate of consumables depletion. 

You might find that it’s not necessary to have a dual voltage input & you can get by with just 120 volts. 


Welders that can do many processes are rarely inexpensive. There are several budget-friendly models which often come with a lot of trade-offs to achieve a lower price. 

Nevertheless, a costly multi-process welder is more worth it in the end. Purchasing a multi-process welder, instead of 3 different kinds of welders, makes better sense if you only need to use additional welding methods in your tasks.  

Bottom lines

When you are considering buying a multi-process welder, remember to follow our detailed buyer’s guide. We believe that our tips will allow you to find the best combo welder that meets your needs.
