INSTALLATION RECOMMENDATION
Installation Environment
BOSS ARC Series is designed for use in hazardous environments.
Examples of environments with increased hazardous environments are -
In locations in which freedom of movement is restricted, so that the operator is forced to perform the work
in a cramped (kneeling, sitting or lying) position with physical contact with conductive parts; In locations which
are fully or partially limited by conductive elements, and in which there is a high risk of unavoidable or
accidental contact by the operator, or in wet or damp hot locations where humidity or perspiration
considerable reduces the skin resistance of the human body and the insulation properties of accessories.
Environments with hazardous environments do not include places where electrically conductive parts in
the near vicinity of the operator, which can cause increased hazard, have been insulated.
Installation Location
Be sure to locate the welder according to the following guidelines:
l
In areas, free from moisture and dust.
l
In areas, free from oil, steam and corrosive
gases.
l
In areas, not exposed to direct sunlight or rain.
l
Ambient temperature: between -10 degrees C
to 40 degrees C.
