Buyers Guide: How to choose the best Multi-process Welder

A multi-process welder, while being efficient, isn’t easy to buy. The market has been expanding since it’s the initial release, and with constant innovations, choosing the right one for your needs and preferences might seem impossible. Therefore, we have compiled a buying guide that lists the basic features to help you with your final decision.

  1. Preference

Before moving on to any aspect of the buying process, you need to search for the essential process of each welding machine. MIG welding, TIG welding, and stick welding are the most common processes that work differently for a diverse range of purposes.

Some users may decide to buy an expensive MIG welder making them lose out on other welding jobs. As a beginner or professional, your best bid should be on a multi-process welder- 3 in 1 or 4 in 1. It allows you to weld a variety of materials such as steel, stainless steel, iron, cast iron, aluminum, and metal alloys within a single component. Some of the modern welders may also contain a plasma cutting option for added convenience- it’s a great alternative for stick welding. A MIG/TIG/STICK combination is the best choice if you deal with different materials frequently. A MIG/TIG/CUTTER can be used to weld a variety of metals along with basic construction procedures. If you interact with exotic metal alloys on a daily basis, a combination of TIG/PLASMA/STICK is better for you.

  1. Amperage

After noting your preferred welding combination, the amperage range is the second most important factor. You need to make sure that your unit is capable of providing the required output power for every project. DIY and domestic users usually need at least 150 amperes to tackle household jobs. People who use the machine more regularly, such as an automobile repairer, would need a welder with around 200-300 amperes to deal with car materials.

A range of about 150 amperes to 230 amperes is enough to weld materials with a thickness and strength of about 24 gauge of steel to 0.25 inches of aluminum. Briefly, you need to consider the thickness and material of the metals used most often while making a decision.

  1. Power Supply

This is a major factor to consider while welding. You need to figure out the adequate power supply for your specific unit, and it’s availability before buying a welder. Every welding process is categorized into either constant voltage or constant current supplies. In other words, they are based on AC (alternative current) and DC (direct current). MIG and stick welding utilizes direct currents, whereas the other welding types make use of alternative currents. You need a direct current to weld tough materials, whereas the AC power is better for self oxidizing metals eg, aluminum and magnesium.

If you are looking for flexibility in your welding routine, you need a unit that is capable of providing you with both AC and DC output.

  1. Voltage

The voltage is secondary to the amperage and proportionate to your budget. Let’s assume that you’ve found a great multiprocess welder with a high amperage at a low price, sounds great, right? But what if it needs 220 Volts of input power? Your standard household power outlet only provides 120 Volts, after which you may need to spend extra money and time for installing a secondary power base. But if you need a high voltage for certain jobs, a dual-voltage welder may be great. Most MIG welders allow you to adjust the voltage manually as well.

  1. Ease of use

Welding is a hard process, and some machines ruin the experience with an even more complicated design and interface. Who wants to spend time figuring out a way to adjust the settings? Therefore, it’s important to choose a welder that can be set up without any hassle. It should be easy to use and needs to have a detailed instruction manual to aid the beginners. A user-friendly interface and control would make it more convenient.

Most modern multiprocess welders come with digital screens and precise control buttons. You can fine-tune your settings by just turning a knob or pressing specific buttons to suit your job. Not only will it reduce any errors and mistakes, but a clear and accurate indicator would lead to a smooth finish.

  1. Weight

Let’s face it- as a welder, you would need to move around a lot to work on various DIY projects, industrial welding jobs, or for casual outdoor welding purposes. Hence, you need a multiprocess welder that is compact and portable. A lightweight welder is preferred, but at times, it may affect the performance. But a heavy device can’t be moved around daily.

  1. Additional features

As we mentioned earlier, the multiprocess welder market is concentrated. Each manufacturer is competing with the next by introducing unique features at an additional cost. However, not all of them are useful to you. Before being blinded by the marketing gimmicks, you need to analyze the use of that particular feature. Do you even need it? More often than not, a basic welding job won’t utilize any of those extra elements.

  1. Budget

What’s the use of this buying guide if you don’t have a budget? You could easily go and buy the most expensive product assuming that it’s perfect for you. However, contrary to popular beliefs, price is not proportionate to quality i.e., an expensive multiprocess welder doesn’t promise high quality. You need to understand your needs before planning to buy a product. Do you need to weld heavy-duty metals? Are you an amateur welder? Where is your job located? Once you pinpoint your basic requirements, you’ll realize that many average-priced welders would be sufficient for day-to-day jobs. However, if you’re looking for extra features or industrial equipment, you may need to set aside a budget of $1500.

Frequently Asked Questions (FAQs): About Multi-Process Welders

Q: Are combo welders worth buying?

A: Multiprocess welders allow welders to carry out multiple welding jobs from a single component. It makes it easier for the welder to complete jobs such as fabrication, construction, workshop activities using a single device and power source compared to using three different welders. Not only is it cheaper, but it also saves time and space since it completes the jobs at a faster pace. Moreover, they are convenient and can be adjusted according to your needs.

However, some multi-process welders may weigh a lot; hence mobility would be a constant issue.

Q: What is the easiest welding to learn?

A: MIG welding is the easiest welding to learn. Most MIG welders allow you to set your wire speed, voltage control settings, and shielding gas amount according to the jobs need. Moreover, it also gives a cleaner weld without any slag and lets you weld a wide variety of metals and their alloys.

Q: Is stick welding better than MIG?

A: MIG welders can weld extremely thin metals (24 gauge) and tend to produce beautiful, smooth, slag-free, and splatter-free welds. Moreover, the welding process isn’t interrupted by the need for stopping and replacing the electrode stick since gas tends to last for a longer time. Stick welders, on the other hand, are less sensitive to paints, wind, and corrosion. The ground clamp can be attached from much further away, whereas the rods can be changed easily for special welding purposes. Moreover, the direct current allows you to alter the polarity of the electrodes to decrease burn through while welding thin metals.

Q: What is the strongest weld?

A: Stick welding is known to produce the strongest welds since it can weld relatively thicker materials without reducing their strength. Moreover, it is the only option for welding cast iron along with other dirty materials. However, if you’re looking for high-quality welds, TIG welders are the way to go.

Q: Is welding stronger than bolting?

A: Welding doesn’t deteriorate the strength of the metals due to full penetration; however, the end product is greatly affected by the welding quality and the materials used. Fillet welding is weaker than MIG welding; hence the strength varies. On the other hand, bolted connections decrease the strength of the materials because of a reduction in surface area and small lever arms by drilling holes and overlapping plates. A simple bolted connection should be used for amateur jobs since you’d be confident about its strength regardless of the capacity of the connection.


You are aware of the best multi-process welders in the market. You need to make sure that your choice matches your budget and needs to avoid paying excess cash for useless features. Before buying one, it would be helpful to read our extensive buying guide. Each welder is made for a different purpose, and a high price doesn’t symbolize good quality.
