Multi-Process Welder Buyer’s Guide

Weight and Portability

It stands to reason that if you’re looking for the best multi-process welder, you’re planning to take on a wide range of welding projects. This often means that portability is a consideration.

Although few multi-process welders are truly lightweight, it’s essential to find one that’s on the lighter side if you’re going to move it around the workshop often.

Best Multi-Process Welder

Technologies and Welding Processes

Multi-process or combo welders are usually capable of handling at least two or three different welding styles. Some may even add in a fourth, but you should manage your expectations if you don’t want to spend a fortune.

Remember that most people turn to multi-process welders to save the money required for buying more than one welder.

Multi-process welders can feature a wide range of welding style combinations. However, the most common combo you’ll find is MIG, stick, and TIG. It’s very easy to incorporate MIG and stick onto a TIG platform and blend all those technologies.

Other welders may add in a plasma cutter function, albeit at a low to medium output. But, in most cases, you should still be able to use the plasma cutter on a multi-process welder to go through rust, aluminum, and thin- to medium-thickness metal.

Duty Cycle

Some manufacturers will list duty cycles, but you should always take them with a grain of salt. Because you’re dealing with more than one welding style, the duty cycle may not be consistent across the board.

On top of that, there are even more output ranges to account for in multi-process welders.

Overload Protection

Overload protection is a must-have feature in any welder. When it comes to combo welders, the overload protection is even more important as switching between different welding styles can take its toll on the machine a lot faster.

Dual Voltage

A dual voltage power supply can be a game–changer. Consider the degree of freedom you can gain by not being dependent on a specific type of outlet.

On top of that, you’ll need 220 volts to get higher output. This essentially means that you should be able to cut through thicker materials in a single pass, at least if the circuit allows you to draw enough current from it.


Multi-process welders are rarely cheap. There are some budget-friendly models on the market, but they’ll often make plenty of compromises in hitting the lower price tag.

However, more expensive multi-process welders are worth it at the end of the day. If you need to use more welding styles in your projects, then buying a combo welder makes more sense than buying three different types of welders.

At least as long as you don’t need them for industrial-type tasks. For those, you’ll probably need multiple dedicated welders for performance and longevity. But, for the average consumer, a combo welder is the way to go if you want the versatility without committing to buying multiple welders of different types.

Best Place To Buy A Multi-Process Welder Online

While you could certainly find mp welders in a local industrial store, there are also numerous places where you could order one of these machines online – eBay, industrial sites, etc. Additionally, there are always people who post their offers on tech sites, which might or might not be related to whatever you are looking for. However, these machines aren’t toys, food, or something you should take too lightly – buying one will always be a costly investment, not to mention the risk of purchasing faulty equipment.

The safest place where you can order this tool–online or in-store–is Amazon. Apart from being the most popular and reliable online service, this online market has a strict set of rules that apply to users on both ends: vendors and buyers. They also provide free shipping to their customers in some areas.

One of the best things about Amazon is that you, as a customer, are entitled to use their return/refund policy. People ship their items overseas all the time. Even if your vendor is in the near vicinity, an accident can occur at any time. Your package might be delivered to you in a damaged condition – that’s where return policies come into play.


The best multi-process welder is arguably the one that can handle all your projects. If you’re looking for a welder with dual voltage and at least three welding technologies, then you’re already on the right track.

As you can see from the top five picks presented in this article, the decision may often come down to the number of accessories or the raw power output across specific welding styles.
