Tig Welding Safety
During tungsten inert gas, or TIG, welding, the worker uses an electric charge that creates an arc surrounded by the gas. The welder should wear appropriate safety gear, check equipment and keep safety first.

Protective Gear
-
Welding helmets should have a glass front rated 11 or above. The welder can be exposed to ultraviolet light radiation from the electric arc. All skin should be covered, including covering your hands with welding gloves. Uncovered skin can get burned, so covering up the neck and hands is important. Work clothing should not be made from synthetic materials, as a stray spark can cause them to melt. Wearing a welding helmet protects your eyes and face.
Inspecting Gear
-
The welder should inspect all electrical connectors and cables for proper insulation. The connections for the equipment should be able to handle the amount of electrical current coming through them.
-
Other Considerations
-
Clamps and vices are useful for holding metal during welding. Protective screens should be set up around the welding area to protect others from exposure. The welder, while working, should not weld in an area that has excessive moisture to avoid being shocked. Clamping the metal to a bench or table can prevent it from being dropped by accident.
