About

This is a new and experimental class for the Welding Studio. It is the inaugural use of BARN’s new plasma table and three plasma cutters.

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.  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.

Small class size (3) creates an intimate learning atmosphere for one-on-one learning and direct mentoring.  Work space is limited on the plasma table.  Students will take turns using the three available plasma cutters.

The class begins with a safety briefing.

Safety and Personal Protection Equipment will be provided by BARN.

Students must wear natural fiber clothing, closed toe shoes, no stretch fabrics.  Dress warmly, the studio may be cold.

Minimum class size is 2.  If only one student has registered 60 hours before the class, the class will be cancelled.
