Plasma Cutter Buying Guide
A plasma cutter greatly improves your fabrication ability, but a cheap plasma cutter may not get the job done. Even if you don’t need one for industrial use, here are the primary factors you should consider when looking for the best plasma cutter.
What Type of Cutting Are You Doing?
The work you plan to do is your main deciding factor. If you’re only cutting sheet metal, you don’t need a big 200 amp plasma cutter intended for 3/4-inch steel plate. For auto bodies and other light-duty chores, a smaller machine costs less to purchase and probably runs on 120 volt power for additional savings.
What Power Levels Are Required?
When considering power needs, first is output power and duty cycle. This decides the upper limit you can cut, and it’s also going to determine whether you need 240 volt input or if you can get by on 120 volts. You may decide it’s more versatile to have 120/240 dual voltage input power.
Do You Need an Air Pressure Source?
Some machines come with a built-in air compressor. Others require external air from a separate air compressor. Depending on the size of the plasma cutter, an onboard compressor can add significant cost. Although you may need to buy a separate air compressor, it can probably double as a power source for spray guns and air tools.
Do You Need Advanced Features?
There are a few options that add a lot of convenience to the process and make the machine easy to use.
- Different Arc Starting Types: Some machines start the arc without touching, some you drag the torch to get going and others scratch start like a welder. One drawback to the high frequency no-touch type of arc starting is that it causes interference with digital equipment like digital gauges, mobile devices like phones and tablets, and interferes with computers and CNC control units.
An alternative to high frequency starting is blowback torch technology. These torches use air backpressure from the work surface to operate a switch that fires the torch. This approach delivers no-touch starts but doesn’t interefere with digital devices, allowing CNC usage.
- Do You Need Computer Numerical Control? CNC allows a computer control the process. This requires a special rack-type table that moves the torch on a grid system.
- Does It Have Air Flow Adjustment? Some machines will allow you to set the amount of time to continue flowing air to cool the metal after you stop cutting. Others include a similar function as an automatic setting.
- Specialized Automatic Settings: Some machines change air pressure or electrical current settings to match how you’ve equipped your torch or to adjust for changing conditions. Some have factory presets and you select material and thickness to start cutting.
- Automatic Torch Re-Strike: This function allows the machine to cut across gaps in the metal surface. This can be obstructions such as bolt holes, component cutouts and materials like expanded metal, mesh or grating. An electromagnetic sensor can detect gaps in the metal surface being cut. The torch shuts off automatically as it crosses the gap, then re-strikes the arc when it’s over a metal surface again.
Warranty periods vary widely, from a few months to several years. The company behind the warranty needs to honor its commitment and provide quick service. Some brands have nationwide dealership networks, making for a quick turnaround. Others might only have one service center in the country or require shipping overseas. Make sure whether you cover the cost of shipping a machine back to the manufacturer or if the maker will bear the cost.
