Need to learn some essential techniques for using a plasma cutter?
Then, you’re at the right place.
Read our step by step plasma cutter using techniques that will definitely help you to increase your efficiency, prolong the life of your equipment and improve your cut quality.
Plasma cutters are easy to use and very convenient. Using a plasma cutter improve productivity and lower cutting costs. This is the tool that doesn’t require any preheat cycle, cuts any electrical conductive metal, portable around worksites, reduces the heat-affected zone and produces a cut with small kerf.

Step By Step Using Procedure Of A Plasma Cutter
Step 1 - Make Sure The Working Area Is Clean
Before setting up the plasma cutter to start cutting, make sure that the working environment is as clean as possible. If there is dust or grinding debris around the unit, the cooling fan may suck these particles and it can cause serious damage to the unit.
Step 2 - Set Up Stable Work Surface
The working surface needs to be safe. Working with a plasma cutter can be risky if you place and work on a surface that isn’t stable. If you place the metal on a surface that works like a table, make sure that the setup is strong enough to cut on. Using a metal clamp to hold the piece down makes the cutting procedure secure.
Step 3 - Plug In The Plasma Cutter
Make sure that the device is power off and plug it in.
Step 4 - Connect the Air compressor
If the plasma cutter doesn’t feature built-in air compressor, connect the external air compressor to the unit. It will ensure high-pressure plasma stream.
Step 5 - Turn the Air Compressor On
At this step, turn the air compressor on.
Step 6 - Attach The Ground Clamp
Ground clamp is a part of the plasma cutter and also essential to protect the plasma cutter and the user. Plasma cutting involves an electrical charge that melts the metal. So, attaching the ground clamp is also a safety issue. Attach the clamp close to where you need to cut.
Step 7 - Turn On The Machine
Generally, you’ll find the on-off switch behind the unit. Turn on the plasma cutter by flipping this switch into the ON position.
Step 8 - Set The Amperage
Set the amperage control (generally to maximum).
Step 9 - Cut The Metal
Keep the nozzle end on the edge of the base metal. Push the trigger to start the arc. Get down to slowly move the torch over the metal. If you’ve any templates, use the guide surrounding the nozzle.
Step 10 - Switch Off The Machine
At the end of your cutting job, you should turn off the unit.
Step 11 - Disconnect The Ground Clamp
Don’t forget to disconnect the clamp from the metal.
Step 12 - Turn Off Air
At this stage, by rotating the lever 90 degrees, turn off the air.
Step 13 - Let The Torch To Cool And Wind Up All Hoses
You’ve just finished your cutting job, let the torch to cool. After releasing the trigger, post-flow air lasts for 20-30 seconds. Wind up all hoses and wrap up the torch, airline, and ground line.
