SECTION 3:
INSTALLATION
3.01 Environment
The ArcMaster 200 AC/DC is designed for use in adverse
environments.
Examples of environments with increased adverse
conditions 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 adverse conditions 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
ELECTRIC SHOCK can kill; SIGNIFICANT DC
VOLTAGE is present after removal of input
power.
DO NOT TOUCH live electrical parts.
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.
