3.01 Environment
These units are designed for use in environments
with increased hazard of electric shock. Examples
of environments with increased hazard of electric
shock 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 increased hazard of electric shock
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 follow-
ing guidelines:
• In areas, free from moisture and dust.
• Ambient temperature between 32°F to 104°F
(0°C to 40°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” (300mm) or more
from walls or similar that could restrict natural
air flow 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. Lock-
out/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.
• Electrical Input Requirements
Operate the welding power source from a single-phase
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 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.
Do not connect an input (WHITE or BLACK) conductor
to the ground terminal.
Do not connect the ground (GREEN) conductor to an
input line terminal.
