Buyer’s Guide (Tips & Tricks)
Why Multi-Process Welders are a Good Investment
As the name would suggest, multi-process welders are all about providing you with flexibility on the job. The biggest advantage these machines offer is the ability to switch between different tasks efficiently. Whether you’re working with heavy-duty metal or simply need to tack two materials together for an art project, a multi-process welder can handle it all.
As such, these devices can also provide you with significant savings in the long run. Earlier, we mentioned that many professional workshops are equipped with a wide range of machines. While it may be nice having all of those options to work with, it’s not cheap. Not only does it cost more to buy individual welding equipment, but you also have to take maintenance costs into account.
Last, but not least, multi-process welders are more efficient. Why spend time preparing multiple machines when one welder can take care of it all? Most multi-process equipment lets you perform at least one type of welding technique and make cuts. This alone can cut back your work time, which ultimately helps to improve your bottom line.
What Can a Multi-Process Welder Do?
This all depends on the design of the machine. Many manufacturers offer equipment that has at least two different functions. Though, equipment with three or more techniques is becoming increasingly common. When you’re choosing the best combo welder, it’s important to consider what kinds of tasks you’ll be doing. Here are a few welding disciplines you might see in multi-process welders.
TIG welding requires a lot of skill and practice. However, once you master it, this technique can produce amazing results. It offers more control than other disciplines and doesn’t require flux or a consumable electrode. Multi-process welders with a TIG function usually have a gas valve for argon as well.
Metal Inert Gas welding is praised for its versatility. It can be used to bond virtually any metal. These welders provide a steady supply of spooled electrode, so they can be used with one hand. Like TIG welding, gas is also emitted to prevent oxidation. The great thing about MIG welding is that you can use different electrode spools and gas to work on a variety of materials.
Also known as Shielded Metal Arc Welding, or SMAW for short, stick welding is one of the most basic disciplines around. As a result, it’s very common in multi-process machines. Essentially, this welding technique uses a consumable rod that’s coated in flux. It works on a range of different materials and is relatively easy for any skill level.
The best 3 in 1 welder will have a built-in Plasma Cutter Welding feature, which is commonly referred to as PAW. This technique is designed exclusively for precision cutting. It works by producing an electron arc between a tungsten electrode and the work material. Tungsten has the highest melting point of all metals, so the technique is very effective.
Choosing a Multi-Process Welder
Due to the versatile nature of these welders, there’s quite a bit of variation on the market. Not every piece of equipment is going to provide you with the reliable performance that you need. To ensure that you’re making an investment that you are confident in, keep the following considerations in mind during your search for the best multi-process welder.
Available Welding Techniques
What good is a welder if it can’t do the things that you need it to? Think about the type of work that you do and your skill level to narrow down your options. Having some type of plasma cutter is always a good thing. However, the exact welding methods you get is entirely up to your needs. If you don’t have a ton of experience and need to perform basic welds, you’ll do just fine with a stick or MIG welder. However, TIG welding is great for precise jobs that need to have a professional finish.
Power and Amperage
When it comes to power, take a look at the machine’s amperage ratings, supply requirements, and output capabilities. Amperage refers to the amount of electricity flowing through the welder. Most products allow you to adjust the amperage settings to accommodate materials of varying thickness. Typically, more amps are needed to work on thick materials. So, having a higher amp range is always recommended.
Next, think about whether you want to get a machine that works with AC, DC, or both. Some equipment requires a specific type of current to provide reliable performance. Others have a built-in transformer that can change the current based on the type of welding you’re doing. For example, MIG and stick welding usually uses DC power. However, AC is preferred for TIG. Having a welder that does AC and DC welding only adds more versatility to the machine.
All welders have a duty cycle rating. It represents the amount of time that you can continuously weld at certain power levels before the machines need time to cool. Welding cycles last for 10 minutes. The duty cycle is provided in the form of a percentage. If a welder has a duty cycle of 40 percent, that means that you can run it for four minutes before you need to take a rest.
Before you purchase a welder, take a look at its control systems. Do they look overly complicated or are they something that you can manage? Ultimately, this all comes down to your skill level and personal preferences. It’s never a bad thing to have more ways to customize your weld. But, if you’re not sure what all those settings mean, having a machine that does most of the work for you is a better choice.
Some welders have predetermined settings. This makes it easier for novices to pick up. Also, think about your workflow. Many welders come with a foot pedal for greater control on the fly, a digital display to help you manage your machine, and safety features to give you peace of mind.
Finally, the size and weight of your welder should be taken into account. Multi-process welders tend to be on the larger size because they have to include components for each process. Luckily, manufacturers offer some portability features that you may want to keep an eye out for. Things like caster wheels and durable handles make it easier for you to take the machine with you from job to job.
Finding the best multi process welder to meet your needs is not always easy. All of the products in this guide can perform well in most situations. However, the Lincoln Electric Power MIG 210 is a cut above the rest. The biggest difference that this machine has over the alternatives is four different welding modes. While most devices can perform three different tasks, this one takes things up a notch to provide you with even more versatility. As a result, it beats out even premium models from big brands like Everlast and Lotos.
Ultimately, the Lincoln Electric welder’s superiority comes down to its design. It offers a very user-friendly control system that’s easy to use regardless of your skill level. The welder is also very portable, has a high power output of 220 amps, and has a good duty cycle rating. While it may not have AC compatible for aluminum TIG welding, the three other processes can take care of the task without any issues.
