INSTALLATION
3.01 Environment
The ARC MASTER 185 ACDC / 200 ACDC 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, or
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 are 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
Thermal Arc advises that this equipment be
electrically connected by a qualified electrician.
3.03 Electrical Input Connections
!
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.
3.04 Electrical Input Requirement
Operate the welding power source from a single phase
(185/200 ACDC) or a three phase (200 ACDC) 50/60 Hz,
AC power supply. The input voltage must match one of
the electrical input voltages shown on the input data label
on the unit nameplate. Contact the local electric utility
for information about the type of electrical service
available, how proper connections should be made, and
any inspection required.
The line disconnect switch provides a safe and convenient
means to completely remove all electrical power from
the welding power supply whenever necessary to inspect
or service the unit.
NOTE
These units are equipped with a three-
conductor with earth power cable that is
connected at the welding power source end
for single and three phase electrical input
power.
Do not connect an input (WHITE or BLACK or
RED) conductor to the ground terminal.
Do not connect the ground (GREEN)
conductor to an input line terminal.
