==Safety First==
[[File:Safety First HD2.png|left|150px]]
Here are some safety instructions for the {{PAGENAME}}. Remember... SAFETY FIRST!!!
* Only cut steel and aluminum.
* Never cut any coated materials
* Don't attempt to cut with the compressed air off
* Make sure the vent hood is on and placed near your working area. This will help evacuate the smoke.
* Arc rays can burn your eyes and skin. Wear a welding helmet and there should be no bare skin exposed.
* Never walk on the hoses or ground cable as this could cause damage to the machine.
* Never pull the trigger on the torch unless you are cutting material as this will reduce the life of the nozzle and electrode.
==Description==
==Description==
The plasma cutter is a useful and time saving tool. This machine will cut up to 7/8" mild steel at 10 inches/minute and can roughly sever up to 1-1/4" plate. The pierce capacity is 7/16" so you will need to edge start when cutting thicker material. The torch is hand controlled so you can cut many types of designs. You can use a straight edge or material as a guide to cut various shapes and lines. Be aware that material can get very hot while cutting. Remember to keep body parts away from the cutting portion of the torch to prevent a serious accident. If your shoes have a mesh on top, there is a chance hot sparks and molten metal may burn through.

====Operation====
====Operation====
When operating the plasma cutter be aware of what you are attempting to do and listen to the machine. If you notice a sputtering or hissing noise it could be caused by moisture in the line. When you are piercing thin materials you should hold the torch 90 degrees to the metal. When gouge cutting tilt the torch head at a 45 degree angle to the work piece. Maintain the angle while cutting.

====Demonstration====
For the demonstration you will need to show that you can safely setup and operate the plasma cutter. You will need to mark a piece of scrap material and cut along the line using a guide or free hand.

# Place the fume hood over the area you will be welding.
# Place the fume hood over the area you will be welding to help remove fumes.
# Make sure power and air is connected.
# Make sure power and the compressed air line is connected.
# Attach the ground clamp to your work piece.
# Attach the ground clamp to the fixed work piece. The surface should be clean and paint free for a good connection. Keep the clamp close to the cut but out of the way.
# Put on your gloves, jacket, and helmet. You should have no bare skin
# Put on the gloves, jacket, and helmet. You should have no bare skin exposed.
