Guide to Buy Cheap Welders
A Comprehensive Guide to Buy Cheap Welders
While thinking of welding, most people imagine a big workplace with soot-covered hands doing some commercial fabrication. However, that’s not the start and end of welding. There are many more instances where a beginner or an average user will comfortably use a welding machine at their home. This is why cheap welders are appealing to them! They seriously do not need an upscale or highly professional model.
However, cheap welders for sale seem to be an obvious preference even of the professionals. Well, figuring out the best budget welder is actually not so easy, especially for beginners. This is because there are different types and that each of these types has further factors to consider.
For example, after deciding the type, you would have to choose one from that category by determining other factors such as power, duty cycle, and protection features. Thus, to make you, as a beginner or as a budget buyer, choose the best budget welder, this guide is out!
After all, how will you sort through several options available in a specific type category? Well, now, you need not do, as this guide does it for you.
Why You Need a Cheap Welding Machine
Commencing a welding career can be a pleasant or an unpleasant affair. It is somewhat like an art that all of us cannot master. This means all of us can learn but only a few are versatile experts. Well, if you end spending thousand dollars just for learning the purpose, it is really going to stress your budget.
If you have joined a training class or are trying your hands for the first time on welding, investing hundreds of dollars on a new welder is irrational. Thus, it makes sense to get started with a cheap welding machine.
The best cheap welder is perhaps a sensible way to learn the art or skills of welding, which is required for your upcoming simple projects or for taking up some serious job. While the former one would involve trial and error, the latter one would require you to be a bit experienced.
You may proceed to buy a better or advanced model but only if you wish to sustain yourself in this field as a hobbyist or a professional. Still, the fact is that even professionals would first consider buying a cheap MIG welder or a cheap TIG welder.
Buying such a model helps to have a real experience that involves facing all sorts of challenges. You should not get demotivated with the word ‘cheap’. This is because cheap welders do not give inconsistent or unreliable outcomes.
Even the collection of cheap welders has different reliable models. A home welder has a myriad of improvement projects at his disposal. Luckily, finding reliable discount welders no longer means compromising quality.
With the existing collection of cheap welders, these users can now take the benefit of multiple uses. These welders are usable right from fixing a broken chair arm to making creative statues using recycled metals.
The modern options run on electricity and are portable. Some models also work on gas rather than on electricity.
They do support the regular home power sockets due to which there is no need of rewiring or risk of circuit overloading. Cheap welders are capable of fulfilling the diverse needs of welding enthusiasts as well as homeowners, by working on a myriad of metals.
Factors to Consider for Buying the Best Budget Welder
As a fact, there is no single budget welder that comes with a single-size-fits-all capability. This is perhaps why several welding disciplines are offered. Each one comes with its pros and cons that must be considered.
Thus, in other words, it is essential to look for the best affordable welder by considering these pros and cons. Further, there are some more factors to consider whose applicability depends on your requirements.
The biggest requirement is the ability to weld all metals you need it for. When it comes to cheap welders, you will find many designed for only a few metals.
These models are for you if you will be working with a specific metal although a versatile welder capable of welding maximum metals and performing a range of tasks is preferable. Further, you may need a welder that can support both electricity and gas power sources.
Getting these facilities may add a bit to your budget, but you will then obtain the best of both worlds. In case of larger projects, a welder working with a 240v outlet is required. This is to enjoy the optimal flexibility and prevent an upgrade in future by eliminating the need to invest in a welder of a higher power.
So, let’s take a look at all such factors that affect your selection decision once you know which metals you will be working with for welding purpose.
The Welding Process
Welding joins two similar metal pieces either through the process of melting the base and fusing a filler metal or plastic that becomes a strong joint. This joint is formed by the power of a flame or an electric arc.
Mostly, ferrous metals are used for welding and the temperature is usually between 1500 and 3000 degrees Fahrenheit. Following are the different welding processes for you to consider as per the metal to be welded and skills required:
- Stick/Arc Welding or Shielded Metal Arc Welding (SMAW): This process involves an arc welder using a replaceable electrode to aid the arc. Shielding takes place by melting of the electrode’s outer flux coating. It is the electrode that provides the filler metal. This welder needs a significant amount of cleanup and frequent electrode (rod) replacements.
- Recommended When: In outdoor and in windy situations
- Recommended For: Cast iron, steel, stainless steel, dirty or rusty surface
- Support for Metal Thickness: At least 18-gauge or 0.16 cm
- Skill Level: Moderate
- Metal Inert Gas (MIG) or Gas Metal Arc Welding (GMAW): This process involves a wire feed welding machine that generates an arc to join metals by heating. The arc exists between the metal and incessantly fed electrode (solid wire). Shielding, in this case, comes from an externally provided gas.
- Recommended When: Ease of use is on priority, metals are thinner, high speed with cleaner weld and less cleanup is required, flux cored process is also needed
- Recommended For: Aluminum alloys, cast iron, steel, stainless steel
- Support for Metal Thickness: 26-gauge or even thicker surfaces
- Skill Level: Low
- Flux Cored Arc Welding: This is gasless welding that MIG welders can perform. Here, metals are joined with the help of an arc between the piece and replaceable electrode wire. The weld is cylindrical with the flux coat being within the shielding. Depending on the type of wire in use, this process takes place even without the shielding gas.
- Recommended When: In windy condition, deep penetration is required on thick surfaces, flexible and portable positioning is required
- Recommended For: Aluminum alloys, steel, stainless steel, dirty or rusty surface
- Support for Metal Thickness: 26-gauge or even thicker surfaces
- Skill Level: Low
- Tungsten Inert Gas (TIG) or Gas Tungsten Arc Welding (GTAW): This process involves using a TIG welder that works with a generator of high frequency. The arc is formed between the piece and non-consumable electrode of tungsten. Shielding comes from an inert gas such as argon. It is not necessary to use the filler metal in this process.
- Recommended When: Precise, high-quality welds or highly appealing beads are required
- Recommended For: AC for aluminum and magnesium, DC for copper, steel, brass, stainless steel, titanium
- Support for Metal Thickness: Both thin and thick surfaces
- Skill Level: High
In case your use is up to simple joining tasks, a cheap MIG welder is perhaps an ideal choice. The MIG process is perhaps the easiest to study and apply. It is also capable of welding common metals and thick surfaces via several passes. It can do a majority of jobs of a stick welder without using the same number of consumables.
In case precision is your topmost priority, a cheap TIG welder is your friend. You can accurately join thin metals with lower warps or deformation than usual. You can expect the output to be of x-ray quality.
The stick welding process hardly needs anything in terms of equipment due to which it is easiest to find a better welder performing it for less money. Well, you can perform this process on most metals, especially if they are rusty or dirty. Further, only stick welders are easier to use outdoors than the welders in any other category.
There are even multi-process welders that can do two or more of these welding processes. However, it may not be easy to maneuver these models.
Applications and Power Output
Before you choose a welder, it is critical to consider its common uses. These can be repair, automobile body, farm, general maintenance, or construction. Each welder is made for one or more of these applications, which is determined by its duty cycle, rated output, and other aspects.
For instance, a stick welder is ideal for repairing a railing’s wrought iron. Similarly, a heavy-duty repair requires a multi-process welder that can tackle different metals of diverse thickness.
Then, for light repair on steel or aluminum up to 3/16-inch thick, a rated output of 130-amp and a duty cycle of 20-30% are essential to perform a majority of your tasks.
In case of fabrication jobs, a more powerful welder generating an output of a minimum 200 amps as well as having a duty cycle of 40% is needed. For such tasks, cheap welders will not suffice in most situations.
As a conclusion, choose a welder with sufficient amperage so that a consistent root pass is guaranteed. If the first pass itself is dissatisfactory, the subsequent passes will not cover for it. So rather than buying cheapest welder possible, go for the cheapest welder that can give you a chance to make a smooth root pass consistently.
The AMP rating gives a better insight to a welder’s power potential to weld thick or thin metal surfaces. A higher AMP rating is required for welding thick surfaces than usual. For thinner surfaces, this rating should be low or else you will end up melting the metallic surfaces rather than joining them.
Welders usually operate on 110 or 220v circuits. However, there are many models that support dual voltage and eliminate our reliance on a 220V circuit.
Nevertheless, for home use, 110v models are ideal. For welding thicker surfaces, a welder with a power input of 220v and the greatest max AMP rating is required. It is vital to understand that more voltage does not mean greater power. In the absence of electricity, a gas-driven generator can suffice.
A welder may possess all the required features and specifications but it should be easy to carry to different working places. Many cheap welders are compact and small due to which they are portable.
If you will be performing small repairs more often, an ultra-portable welder is ideal. While the power may be a bit less than that of a bigger model, there would be no transportation issue. Most hand welders are within 70 lbs.
Gauged in minutes, duty cycle states how long the machine can smoothly and safely generate a current within the duration of 10 minutes. A welder with 20% duty cycle needs to rest for eight minutes after two minutes of incessant welding. Thinner surfaces need lower duty cycles.
Heat Overload Protection
This is perhaps a must-have feature on a cheap MIG welder. It allows the welding machine to stop welding and shut off in case of overheating, which protects not only the welder but also you and your work area.
