Operating procedures

5.3.1

Operating safety precautions

Comply with all ventilation, fire and other safety requirements for arc welding as established
in the section "SAFETY PRECAUTIONS".
1. Because of the radiant energy of the welding arc and the possibility of drawing an arc
before the helmet is lowered over the face, the operator should wear flash goggles with
filter lenses under his helmet. The helmet filter plate should be shade number 11
(nonferrous) or 12 (ferrous). All those viewing the arc should use helmets with filter
plates, as well as flash goggles. Nearby personnel should wear flash goggles.
2. The radiant energy of the arc can decompose chlorinated solvent vapors, such as
trichloroethane and perchlorethylene, to form phosgene, even when these vapors are
present in low concentrations. DO NOT weld where chlorinated solvents are present in
atmospheres in or around the arc.
3. DO NOT touch the electrode, contact tip or metal parts when power is ON: all are
electrically energized (HOT) and can cause a possibly fatal shock. DO NOT allow
electrode to touch grounded metal. It will create an arc flash that can injure eyes. It may
also start a fire or cause other damage.
