What are Welding Generators?
A welding generator consists of a fuel-run engine that generates electricity to run welding equipment-amongst other things. They produce high voltage, which means they can adapt to the current circuit to meet your voltage needs.
Welder generators come in a wide variety, with many features. They can accommodate different types of welding processes a stick, MIG, TIG- as required.
Why Should I Use Them?
You might be thinking, why should anyone spend money by investing in a welder generator? Let us tell you why.
Regardless of your occupation, you can benefit significantly from a welding generator because it is easy to use and reliable. If you work in construction or build for pleasure, you will find these especially helpful.
Besides, it generates electrical power, and you can hook this generator to any appliance you need to use. Yes, that’s right! They are not exclusively used for welding equipment. You can attach a ratchet, drill, or even a coffee machine to these generators, and it will power them.
If you work away from primary electrical power sources, this generator will come in handy. It will power your device, whether welding or others, without any hassle. So, you won’t have to worry about a stable electrical connection or voltage the next time you set out to work?
The primary use for this two-in-one device is a generator. If you live through a power outage or need power at your construction site, this generator can act as a primary electrical source.
Welder generators are safe to handle, simple and have an efficient performance level. They are also multi-functional; consumers will no longer have to buy separate equipment for a specific function; instead, they can rely on the welding generator. It saves not only space but also money.
What Are the Pros & Cons
Each machine comes with its pros and cons; however, some general aspects of welding generators may or may not appeal to the consumer.
- They are powerful machines, producing enough electricity to power more than one piece of equipment in your work zone.
- They are built to be durable. A welding generator can withstand any weather condition or the hazards of a construction zone. They have a strong build which aids this quality.
- They can be transported from place to place by attaching a wheel kit or other means. Pipe-built generators are the easiest to transport.
- They can serve as power generators for your home or work. Since they produce electricity, there is no rule forbidding you to employ it for other uses. A medium-range generator can generate 11000W of power. It can easily drive heavy machinery. Furthermore, if you experience natural calamities like floods or snowstorms, the generator can provide emergency power.
- They produce stable voltage, thus can your machinery with whichever voltage it requires. Therefore, you don’t have to wire your project size to accommodate 240V tools especially.
- They have versatile features. If you often require to weld with the stick, MIG, and TIG or a plasma cutter, you don’t need to break the bank looking for different machines for each; a welding generator can perform these tasks. However, all welder generators do not have this multitasking feature, and you will have to find the right one for it. Since they run on a stable and high current, they provide excellent welding output.
- The most significant factor is the price. Even if you aim for a low-range welding generator, you will be paying about $1500. And unfortunately, the welding generators with this price tag are relatively small and have fewer features. However, a decent high-range welder generator will easily cost $10,000.
- They are too heavy to carry. While these generators are portable, it is challenging to transport them without additional facilities. The larger the generator, the more it will weigh and the more difficult it will be to transport. You will have to use a trailer trolley or a crane, depending on the size, to move it. So, if you can’t arrange this transport, you will probably have to get a smaller generator, which may or may not meet your needs.
What to Consider When Buying a Welding Generator?
Before you jump to buy a generator that may not suit your requirements, consider some factors. Following are some aspects of a generator you need to contemplate over to buy the right one for you:
Type of Welding Process
Most welding generators support stick welding since it is the most common type. However, high-grade welding generators provide TIG and MIG options too- convenient for remote welding. But if you mostly work with stick welding, you do not need to invest in the other kind.
The duty cycle tells the duration for which the machine will work at full power. For example, if the generator has a 50% duty cycle and you are welding for 20 mins, the generator will run on full power for 10 of those minutes. A 100% duty cycle is ideal but also costly.
Most generators produce AC power, but this cannot drive heavy welding equipment. However, if you want to work on magnetic metals, DC output will not work; you will need AC power instead. An inverter is used to convert this AC supply to DC power and run the machines. Different generators will produce different amounts of DC amperage. Higher amperage is required when welding thicker materials.
So, depending on the task you have to perform, you will have to deduce the amperage you need and then decide.
Power output is a significant factor in choosing a welding generator. If you intend to perform simple tasks like mending objects, go for a less power output generator. But, if you want to do heavy-duty work, naturally, you will need a heavier output. However, the minimum production must be 5000W for satisfactory performance.
How you intend to transport your generator can also affect your decision, especially if you work at multiple sites. If you can set it up at the back of your truck, buying a larger and heavier option may be possible. Some large generators come with protective cages or wheelsets to aid transport.
However, if you will be moving it around a lot, it makes sense to buy a smaller or lighter generator. Otherwise, it will be too cumbersome to carry the generator to the worksite.
The type of fuel required by your generator will depend on the model you purchase. Most generators run on either gasoline, diesel, or liquid propane.
Gasoline is the cheapest option. In winter, gas engine generators are relatively easier to start. They also have a low fuel consumption. But they should only be used at sites with good ventilation; otherwise, they risk igniting.
Jobs of longer durations require diesel-powered generators as they provide a long run-time. So, diesel is an economical option when working for a longer time. But, in cold weather, it cannot be easy to start. It does not risk ignition, but it gives off toxic fumes, making them unsuitable for indoor work.
Propane is the most expensive of the three. It has a longer shelf life than gasoline- which can go stale. It can be used indoors because it burns clean and does not need to be in a ventilated area. Despite its benefits, it is rarely used because of its cost.
Loud noise can make working difficult and also disturbs the people around. If you live in a city and work in a congested neighborhood, you will need to consider the noise level. It is best to get a generator with a noise level lower than 90dB in such cases.
If you live in a remote area, like a ranch, you can overlook this aspect. In such cases, noise-cancellation headphones will do the trick.
Ease of Use
While more advanced welding generators provide more controls and features, they can be confusing to some people. Most generators are easy to use and adjust to your work. Before you take the generator to your job site, familiarize yourself with the controls and meters for a better experience.
If you intend to get a generator for small-scale projects or emergency power, getting an industrial-grade welding generator will not be necessary. On the other hand, if you plan to use several welding machines, a generator with higher power capabilities will be better suited. Before you buy a generator, consider how much power you need from it and what functions are necessary for your task.
Accessories like extension cables, electrode hoses, clamps, and welding guns are necessary for welding. It would be convenient if some accessories are provided with the generator.
