IMC's metalizing wire is always recommended. Only wire which is properly drawn, spooled and packaged should be used. 9-12 are appropriate for our system to protect the eyes from the electric arc. Goggles or helmet should be worn to protect the eyes from flying particles. Standard safety glasses are not enough protection.
Some metals are toxic and others can be damaging to the respiratory system.
Different types of metalizing wire produce different types of fumes, gases, and dust. To protect against any of these problems, we recommend a hood type ventilation system, with a continuous flow of filtered air. Intense ultraviolet radiation is emitted by the arc and can cause serious burns to exposed skin. Gloves are also recommended as well as long sleeve shirts. Magnetic fields from high electric currents can affect pacemaker operation.
