About
Cut shapes out of flat sheet steel. Make an idea into hard reality.
Plasma cutting uses a highly focused electric arc and compressed air to cut steel. Wiki (paraphrased) describes the process thusly: Plasma cutting involves creating an electrical channel of super-heated, electrically ionized gas i.e. plasma, through the work piece forming a completed electric circuit. Compressed gas is blown through a focused nozzle at high speed. The electrical arc ionizes some of the gas, thereby creating an electrically conductive channel of plasma. As electricity from the cutter torch travels down this plasma it delivers sufficient heat to melt through the work piece. The compressed gas blows the hot molten metal away, thereby cutting through the work piece.
Participants will use a plasma cutter to create a design in 16 gauge steel (roughly 3/32nds). Each student will have a 2 foot square sheet of steel to work with. Bring a design to work with. Detail should be at a level you can draw with a sharpie or soapstone and trace with a somewhat awkward implement while wearing gloves.
Details:
- There is a $30 materials fee that will be included in the cost of class for steel 2'x2', cutter tip replacements, consumables and PPE.
- Tuition assistance is available. Click here to fill out our simple application before you register.
- Work space is limited on the plasma table. The four participants will take turns using two plasma cutters.
- BARN will provide Personal Protection Equipment (PPE)
- Participants must wear long sleeve shirts and pants in natural fiber clothing and closed toe shoes (preferably leather or cotton). Stretch fabrics are prohibited.
Instructor:
Sarah K. Glaser has been a certified pipe and structural welder since 2012 and a Certified Welding Inspector (CWI) since 2019. She's put her welding skills to use in shipyards, sheet metal fabrication shops, and, for the past six years, in the rope access industry. When she's not repairing America's hard-to-reach infrastructure from ropes, she's creating educational freelance illustrations.
