2.04 Installation Recommendations
2.04.01 Environment
The ARC MASTER 300 MST is designed for use in hazardous environments.
Examples of environments with increased hazardous environments are:
a. 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.
b. 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.
c. In wet or damp hot locations where humidity or perspiration considerably 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.
2.04.02 Location
Be sure to locate the welder according to the following guidelines:
•
In areas, free from moisture and dust.
•
Ambient temperature between 0 degrees C to
40 degrees C.
• In areas, free from oil, steam and
corrosive gases. • In areas, not subjected to abnormal vibration
or shock.
• In areas, not exposed to direct sunlight
or rain. • Place at a distance of 12” (304.79mm) or more
from walls or similar that could restrict natural
airflow for cooling.
