Buying Guide – How to Choose the Best Dual Voltage Plasma Cutter for Home Use?
The best dual voltage plasma cutter for home use will surely improve your fabrication ability. While an inferior quality product will not deliver the expected result.
Here are a few primary factors to consider when buying the best-rated plasma cutter.
Cutting Ability
The best plasma cutter can cut a wide range of materials of different thicknesses. You will find many better models than others in cutting certain thicknesses and certain metals.
When choosing a model, learn its compatibility with metals and thickness. Make sure your selected model is capable of handling your job.
Pilot ARC
A good-quality plasma cutter comes with a pilot ARC feature. This feature lets a user cut metals without making contact between the torch tip and metal. If you are wondering what is the benefit of it?
Well, using a pilot ARC, you can cut rusty, painted and rough metals without hassle. While working with a rusty surface, remember to clean the area where the ground clamp is connected. Also, if your project is to cut mesh sheets, you have to start and stop the torch as it stays lit during the continuous arc.
Consumables
Replacing consumables is a must, and it is an ongoing cost after buying a plasma cutter. Now, what are the plasma cutter consumables? Swirl ring, shield cap, nozzle, electrode, and the retaining cap – these 5 parts are the consumables of a plasma cutter.
The life expectancy of these consumables is different and depends on several factors. Moreover, they will damage over time. However, the quality of the consumables should be excellent. Here, the general rule is, the more expensive the plasma cutter is, the consumables will be of better quality.
So, look for a plasma cutter that has long-lasting consumables. At the same time, replacement is easy when necessary.
Duty Cycle
A plasma cutter can’t work continuously for several hours. You will need to shut it down after a specific time to prevent overheating. The time frame of a plasma cutter’s safe and continuous use is known as the duty cycle.
Now, what is the meaning of the 60% duty cycle of a plasma cutter? It means you can continuously operate it for 6 minutes before you leave it to cool down.
When it comes to choosing the best plasma cutter for home use, a 50% duty cycle is good enough to get the job done. However, if your project requires some mechanized cutting, a plasma cutter with a 50% duty cycle would be beneficial.
Weight & Portability
Weight is always an essential factor, especially if you need to carry your plasma cutter to the job site. The good news is that most plasma cutters for home use are built with portability in mind.
Portability boils down to weight, size and shape. However, if you buy a pneumatic plasma cutter, it might add additional weight.
Always look for a lightweight plasma cutter with a carrying handle.
Cut Finish
Cut finishes vary from plasma cutter to plasma cutter. A cheap plasma cutter will never deliver the same cut finish that an expensive plasma cutter delivers.
An excellent cut is necessary to avoid after-process cleaning. Determine what finish you need regardless of thinking of a low-priced or high-priced plasma cutter. This will help you find a good quality plasma cutter.
Safety
Safety is a mandatory factor that you must not overlook. Overload protection and overheating protection are essential features to consider when buying the best dual voltage plasma cutter.
Along with the plasma cutter, buy MIG or TIG gloves to work safely. Avoid wearing synthetic gloves and buy leather.
How to Set Up the Best Dual Voltage Plasma Cutter?
Setting up a dual voltage plasma cutter is not a challenging task. Follow the below step-by-step guide carefully.
Step 01: Wear safety gear as mentioned in the issued handbook. A welding helmet will protect your eyes from radiation. Also, a pair of welding gloves will keep your hands safe.
Step 02: Connect the plasma cutter to an available power source.
Step 03: Connect the cutting torch to the plasma cutter.
Step 04: Ensure that the ground clamp is connected to the plasma cutter. Also, securely attach the clamp to the workpiece. Moreover, ensure the connection point of the clamp and workpiece is not rusty or painted.
Step 05: Double-check to make sure all the connections are attached firmly.
Step 06: Adjust the setting of the plasma cutter according to the material thickness.
Step 07: Now, briefly hold down the trigger on the torch to check if there is any airflow. If you experience an airflow, start cutting material.
What Consumables and Parts Are Necessary to Start Using Plasma Cutter at Home?
Consumables and other parts are extremely valuable for using a plasma cutter to make an accurate cut. But a beginner or homeowner might not be aware of the importance of consumables. This unawareness can lead them to misalign everything and ruin the whole system.
Here are the 5 integral consumables to consider when buying a plasma cutter.
The Shield
Molten metals and sparks fly around when working with a plasma cutter. The shield protects other consumables efficiently from these flying things.
Retaining Cap
It holds the other consumables together and is positioned on top of the stake up.
Nozzle
Primarily, it is used to funnel the gas flow and focus the plasma arc. Simultaneously, it shaped and compressed the arc.
Electrode
The current gets carried from the torch to the plate with the help of an electrode.
Swirl Ring
This consumable helps the gas channel in different directions towards the torch and down the machine.
Plasma Cutter Torch Maintenance
Regular maintenance of your dual voltage plasma cutter will help it to work correctly and efficiently. Generally, the consumables of plasma cutters need replacement because they become defective over time. Maintenance of plasma cutters means on-time replacement of the consumables.
The good news is that; most plasma cutters have a consumable chart or diagram which lets you know when to replace the spare parts. Read the below tips and order consumables on time.
- A swirl ring helps air to direct towards the torch. The rule of thumb is that the swirl ring should last for at least 50 electrode/nozzle changes.
- Electrodes made of tungsten. Replace it when you experience a pit of a minimum of 1 mm
- The nozzle size plays a vital role in the performance of a plasma cutter. Change it if you notice an elliptical hole or burns in the nozzle. Improper nozzle size will ruin the cut quality.
Accurate plasma cutting would be nearly impossible with defective consumables. The torch will stop performing, and you will see an error code in the machine.
FAQ
What metals can I cut using a dual voltage plasma cutter?
Cutting electrically conductive materials such as mild steel, stainless steel, alloy steel, copper, aluminum, etc., will be much easier using a dual voltage plasma cutter. However, cutting speed and requirement will vary depending on the thickness of the metal.
What maximum thickness can I cut with a portable and compact dual voltage plasma cutter?
A 110/220V plasma cutter will deliver maximum clean cut up to ½” thickness and maximum severance cut of up to 3/4ʺ thickness. Few industrial-grade dual voltage plasma cutters can cut more than this.
Why does my dual voltage plasma cutter cut on an angle?
A dual voltage plasma cutter can cut at an odd angle for several reasons: worn torch nozzle, less power to the arc, cutting speed is too quick based on the power rating, low gas flow to the nozzle, or you are cutting too slowly.
However, one thing to remember, most dual voltage plasma cutters deliver slight bevel cuts between 1 – 3 degrees. It happens because of the shape of the gas jet that comes through the nozzle. This bevel cut can be reduced but will never go away entirely. More than a 1 – 3-degree bevel cut means there is some problem.
