For best operating characteristics and longest unit life,
take care in selecting the installation site. Avoid locations
exposed to high humidity, dust, high ambient temperature,
or corrosive fumes. Moisture can condense on electrical
components, causing corrosion or shorting of circuits.
Dirt on components will retain this moisture and also
increases wear on moving parts.
Adequate air circulation is needed at all times in order
to assure proper operation. Provide a minimum of 12”
(300mm) of free air space at both the front and rear of
the unit. Make sure that the ventilation openings are not
The FP-95 is not suitable for use in rain.
Refer to additional installation instructions under the
SAFETY INSTRUCTIONS AND WARNINGS (Section 1)
in this manual.
The internal frame of this welding machine should be
grounded for personal safety. Where grounding is manda-
tory under state or local codes, it is the responsibility of the
user to comply with all applicable rules and regulations.
Where no state or local codes exist, it is recommended
that the National Electrical Code be followed.
3.04 Electrical Input Requirements
Plug the input cord into a properly grounded and protected
(by fuse or circuit breaker) mains receptacle capable of
handling a minimum of 20 Amperes. The Firepower FP-95
requires a 120VAC supply voltage.
The Firepower FP-95's power cord is equipped with a
NEMA 5-15P plug and will only connect to a NEMA 5-15P
Consult the nameplate for proper input voltage
and input amperage. The method of installa-
tion, conductor size, and over-current protec-
tion shall conform to the requirements of the
local electrical code. All installation wiring
and machine connection shall be done by a
The National Electrical Code (Article 630B) provides
standards for amperage handling capability of supply
conductors based on the duty cycle of the welding power
source. The FirePower 95 has a 17% duty cycle (1 minute
and 40 secondss of every 10 minutes can be used for
welding).The power cord supplied with this unit complies
with these standards. Ensure that the building supply and
receptacle comply with NEC standards and any additional
state and local codes.
The supply wiring for the welding power source
must be capable of handling a minimum of 20
amperes. The welding power source must be
the only load connected to the supply circuit.
Poor unit performance or frequently opening
line fuses or circuit breakers can result from
an inadequate or improper supply.
Do not connect the FirePower 95 to an input
power supply with a rated voltage that is
greater than 120 +10% VAC. Do not remove
the power cord ground prong.
