2.3 INSTALLATION
Location
The power supply is shipped with the torch and torch
leads, control cable, and work cable connected. The
following steps are required to complete installation.
Select a clean, dry location with good ventilation and
adequate working space.
Air flow under the base and out the rear must not be
obstructed. Operation with the base in direct contact with
the floor will inhibit proper cooling air flow and reduce
duty cycle.
Review PRECAUTIONS (General Information Section) to
be sure that the selected location meets all safety require-
ments.
