SECTION 3:
INSTALLATION RECOMMENDATIONS
3.01 Environment
The ArcMaster 160 S 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 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 that could restrict natural irfl ow for
cooling.

WARNING
Thermal Arc advises that this equipment be
electrically connected by a qualifi ed 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.
• 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.
NOTE
This unit is equipped with a 115 VAC (NEMA 5-15)
plug modeled on the two-conductor with earth
power cable that is connected at the welding
power source for single phase electrical input
power. For 230 VAC operation, have a qualifi ed
person install according to applicable codes, and
instructions.
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.
