Why a CNC is used. A plasma cutting torch is a commonly used tool for cutting metals for a wide variety of purposes. A hand-held plasma torch is an excellent tool for quickly cutting through sheet metal, metal plates, straps, bolts, pipes, etc.
- It is required to wear shaded eye protection while operating the plasma CNC. Welding Cutains - Move the welding curtains so that the CNC is not visable to the naked eye. It is dangerous to look directly at the plasma cutter while it is operating.
The CrossFire™ CNC plasma table was designed as a hobby-level machine to accept a wide variety of available plasma cutters on the market today. The only hard requirement is that the plasma cutter must not use a High Frequency start mechanism in order to initiate the plasma arc.
Follow these steps on how to make a plasma cutter: Firstly, take the DC adapter and connect two wires at the two output terminals of the adapter output jack. Take one of the strongest HB pencil leads. Connect the pencil to the positive part of the adapter output wire and the foil paper with the negative terminal of the adapter output wire.
