SECTION 3: INSTALLATION RECOMMENDATIONS
3.01 Environment
The ArcMaster 300 TS 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.
3.02 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 boundaries that
could restrict natural airflow for cooling.
WARNING 3
Thermal Arc advises that this equipment be electrically connected by a qualified electrician.
3.03 Electrical Input Connections
WARNING 4

SHUT DOWN welding power source, disconnect input power employing lockout/tagging
procedures. Lockout/tagging procedures consist of padlocking line disconnect switch in open
position, removing fuses from fuse box, or shutting OFF and red-tagging circuit breaker or other
disconnecting device.
