1. Safety Symbol Definitions
Means Warning! Watch Out! There are possible hazards
with this procedure! The possible hazards are shown in
the adjoining symbols.
Have only trained and qualified persons install, operate,
or service this unit. Call your distributor if you do not un-
derstand the directions. For WELDING SAFETY and
EMF information, read wire feeder and welding power
source manuals.
Beware of electric shock from wiring. Keep all panels and
covers closed.
Breathing welding fumes and gases can harm your
health. Welding requires good ventilation. If ventilation is
impossible, such as when welding in a confined space,
use an air-supplied respirator.
Welding sparks can cause fire or explosion. Move
flammables away. Do not weld on closed tanks or barrels
– they can explode. Clean tanks or barrels properly.
Arc rays can burn eyes and skin – wear face protection
(helmet or face shield) with correct shade of filter, and
cover exposed skin with nonflammable clothing.
Wear safety glasses with side shields.
