Choosing the Best Multi Purpose Welder – Buying Guide
Buying a 3 in 1 welder is a big purchase since they don’t come cheap. That’s why it’s important to ensure that you are buying the best product that would serve all your welding needs and will offer you the best value for the money. In this buying guide, we’ll go over the main things to consider that will hopefully help you make the right purchasing decision.
When it comes to multi process welders, there is no standard set of welding processes that are included. Some of them can be 2 in 1 with only MIG and TIG capability, while others can be 3 in 1 welders.
The most popular combination is MIG, TIG, and stick welding, which is suitable for most welding needs. Some welders also add plasma cutting capability, which is handy to have for welding exotic metals.
Thin of which welding processes you mostly use. For example, if you’re a beginner welder, you’ll probably be mostly using the MIG process as it is an easier process to learn. It’s also the process you would most often use for bigger projects that require high-strength welds, but which don’t require a high level of cleanliness.
If you need precision and the cleanest look, you would use the TIG process. These higher quality welds are often used by ornamental welding professionals and sheet metal welders.
Stick welding is also a simpler process, which makes it a common choice among beginners and hobbyists. This process is also often chosen because of its versatility as it can be used on different metals. However, it’s not the most efficient welding process and the finished result usually doesn’t look very clean.
As for plasma cutting, it can be used for fabricators. Having this process included in your multi process welder can help you save time. All you’ll need to do is flip a switch, connect a torch and you’ll be ready to cut metal.
All these processes are useful to have in one welding machine. However, your work might be more focused on certain types of welds, so you wouldn’t be using the other processes that often. So consider your needs and choose a suitable multi-process welder, whether it would be one that would be able to handle two or three processes.
Metals Your Work With
Another factor to consider is the materials that you work with, as well as the gauge of the metal that you intend to weld. For example, if you regularly weld steel or stainless, almost any multiprocess welder will do the job.
However, if you also need to weld aluminum, the choice becomes a bit more complicated. For aluminum welding, you would usually use the TIG process but with alternating current. So if you want to TIG aluminum, look for an AC/DC multiprocess welder. But if you mainly weld aluminum, buying a dedicated TIG welder might be a better option since most multi purpose welders are rather expensive and they mostly weld only in DC.
Plasma Cutting Option
Consider also if the plasma cutting capability is necessary for you or not. Some welding jobs might include fabrication that will involve cutting through various metals. However, if your work doesn’t include it, you might prefer to skip on this additional feature that usually adds to the cost of the machine.
The amperage range is another important specification of a multi process welding machine. When choosing one of these units, make sure that it comes with enough output power to handle the projects that you work on.
Depending on the gauge of the material that you will be welding, you would choose a certain amperage. The amperage will also depend on the welding process used. MIG and stick welding processes usually use a higher amperage to weld thicker materials. In TIG welding, on the other hand, the amperage is usually low. Lastly, the amperage depends on the type of material welded since different metals have different melting points.
If you’re buying a multi process welder for home use, a range of 150A to to230A would in most cases be enough. However, for professional use, such as auto repair, you might need higher amperage.
In all, consider the types of materials and their thickness that you will be working with and choose a welder with the appropriate amperage range.
Welders can also use different input voltages. Some plug into 120V outlets, while others into 240V. The 120V option uses standard household power outlets, which is sufficient if you are just welding around the house or workshop. And the 240V option powers off a generator, which can be useful when you work off-site or when you need more power.
You can also find multi purpose welders with dual voltage capability. This gives you the ultimate versatility in the use of the machine as you can plug it in anywhere you want.
Different multi process welders can include various sets of accessories. For example, check if the welder comes with a TIG or MIG torch. Or check if there is a heat control pedal for heat welding. When comparing multi process welders, make sure to take all these included accessories into account.
The ease of use is another factor of a good multi process welder. With a complicated welder, you’ll be spending more time adjusting settings rather than welding. And one feature that makes it easier to use a welder is the display. A good interface can make it easier and quicker to set up and adjust the machine as it will guide you through the process. Having a display also provides more precise control and helps in reducing errors and mistakes since you will be able to easily read all the inputs and outputs.
If you’re looking for portability, the weight of the multi process welder should also be taken into consideration. However, keep in mind that machines with lower weight usually have to sacrifice performance as robust engines and tougher inner parts usually add weight.
Ideally, you would want to find a balance between the weight of the machine and its performance. Though it would still depend on your work. For example, if your projects require you to move around frequently from one location to another, having a compact and lightweight machine might be more beneficial for you.
Some of the other features to look out for include overload protection, lift start, and AC/DC capability. The AC/DC capability is especially important if you work on self-oxidizing metals, such as aluminum and magnesium, for which you’ll usually use the TIG welding process. Buying a multi purpose welder with AC/DC capability will provide the most flexibility in your welding process. However, keep in mind that this capability will also usually come at a higher price.
Setting a certain budget will largely determine which welder you should buy. A good multi process welder can cost as high as $1000 or even $3000, which still saves you money as you get multifunctionality in just one unit. You can also find cheap multi process welders under $1000, but they might not have the same quality or functionality.
When considering the price, don’t forget also about the extra costs. To be able to use your new multi process welder, you’ll also need additional equipment, such as protecting helmets, gloves, boots, etc. If this is something you don’t have already, you will have to add it to your expenses. So factor this in when deciding on your budget for the multi process welder.
