What to look while buying the best plasma cutters under $500?
When planning to get yourself one of these cutting devices, it is important to put a number of key factors into consideration. These include:
Duty cycle
Every plasma cutter requires a resting time after each cutting session and this is referred to as the duty cycle. For DIY lovers who only use their device sparingly during leisure or free periods, this function doesn’t account for a lot. However, if you intend to use your cutter regularly, then be sure to check out the duty cycle of your intended plasma cutter.
Metal thickness
Not all plasma cutters are made the same. As a result it is important to give though to the thickness of the type of metal(s) you intend to cut. A good number of beginner level plasma cutters can give a clean 0.5 inches cut while others can cut an entire inch. Ensure that the machine you are buying can make the required cut on the type of metal you will be cutting is vital.
Power
Be sure you have a source of the required power output for your plasma cutter to function at full capacity. Most standard cutters run on current levels between 40 to 100 ampere. A power supply of 220 watts is great for these machines. However, for those running at above 100 watts, you have to be sure you’ve got the right power source to operate them before purchase.
Consumables
This refers to the parts of your plasma cutter that is used up during operation. You need to be sure that these parts are easily accessible in your vicinity. Virtually all of the cutters in our review have a ready market for their consumables as well as spare parts.
Durability
This factor affects everything you are parting with money for. While there are a good number of reliable plasma cutters under 500$, it is recommended that you go for a model that comes with a warranty. Opt for devices with good cooling systems and high-quality torches that minimize the degree of operational wear and tear.
Conclusion
There is a lot to consider when buying a plasma cutter. It is important to settle for one that meets your need and fits your budget. Our review was aimed at bringing you all the information about the best plasma cutters under $500 that we could find.
Our personal favorite among the list is the Lotos LT5000D Plasma Cutter. It is one of the best you can get below the $500 price mark. It combines precise cutting and ease of use with durability and high efficiency.
