limits shown below shall not be exceeded.

Automatic refers to machine or
mechanized.
For AC welding under wet conditions or warm surroundings where perspiration is a factor,
the use of reliable automatic controls for reducing no-load voltage is recommended to
reduce the shock hazard. Some of the older AC machines do not have an automatic control
and are on load all the time. It is easy to receive an electric shock when the equipment
is not handled properly. |
