2.07 Duty Cycle
Duty Cycle is the amount of arc-on time (actual welding time) during any 10 minute period that a machine can operate at it’s rated
output without damaging internal components. For example, the Firepower FP 95 FC is designed for 17% duty cycle at 85 amps. This
means that it has been designed and built to provide the rated amperage, 85 amps, for1.7 minutes out of every 10 minute period.
During the other 8.3 minutes of the 10 minute period, the Firepower FP 95 FC must idle and be allowed to cool. The thermal cutout will
operate if the duty cycle is exceeded.
If the unit overheats and the thermostat opens, wait 15 minutes for unit to cool.

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 FC requires a
120VAC supply voltage.
The Firepower FP 95 FC's power cord is equipped with a NEMA
5-15P plug and will only connect to a NEMA 5-15P receptacle.
CAUTION
!
Consult the nameplate for proper input
voltage and input amperage. The method

line fuses or circuit breakers can result from an
inadequate or improper supply..
CAUTION
!
Do not connect the Firepower FP 95 FC to
an input power supply with a rated voltage
that is greater than 120 +10% VAC. Do not
remove the power cord ground prong.
3.05 Requirements for Maximum Output
In order to obtain the maximum output capability of the Firepower FP- 95, a branch circuit capable of 20 amperes at 115 to
125 Volts 60 Hz is required. This generally applies when welding
steel that is equal to or greater than 12 gauge (0.105” 2.5mm) in
thickness.
The rated output with this installation is 85 amperes, 18.25 Volt,
17% duty cycle (1 minute 40 seconds out of every 10 minutes
used for welding).
3.06 Installing Wire Spool
As delivered from the factory, the unit is set with a 4” (102mm)
spool.

Be sure to put on proper protective clothing and eye safeguards (welding coat, apron, gloves, and welding
helmet, with proper lenses installed). See Safety Instructions and Warnings chapter included in this manual.
Neglect of these precautions may result in personal injury.
WARNING
Make all connections to the power source including electrode and work cables, as well as remote control
cables, with the power source turned off. These connections could be electrically live with the power switch
ON.
WARNING
ELECTRIC SHOCK CAN KILL! Do not operate the machine with the door open.
CAUTION
!
Do not pull the machine with the gun. Damage can occur to the gun, gun liner and machine. Avoid bending
the gun cable with a sharp radius. Damage can occur to the gun liner.

See Welding Guidelines included in this manual.
1. Make all necessary connections as instructed in the INSTALLATION chapter.
2. Place the WELDING OUTPUT VOLTAGE SELECTOR at the desired setting.
3. Rotate the WIRE SPEED FEED control to the desired setting.
4. Plug the supply cord into a 120 VAC 20 Ampere receptacle.
5. Connect the WORK CLAMP to the workpiece (material to be welded).
6. Extend wire from the gun, and cut to proper stick-out for that type of wire (when welding always maintain this distance).
7. Position gun to where it is at approximately right angles to the workpiece with proper wire stick-out. Lower your welding
helmet and pull the gun trigger switch.
WARNING
Be sure to put on proper protective clothing and eye safeguards (welding coat, apron, gloves, and welding
helmet with proper lenses installed). See Safety Instructions and Warnings chapter included in this manual.
Neglect of these precautions may result in personal injury.
Travel at a speed necessary to maintain a bead width from 1/8" to ¼" (3mm to 6mm) depending on the thickness of the material. For
material that may require larger weldments, either change to a larger diameter filler wire or use multi pass beads. On some applications, it may be necessary to adjust the voltage range to stabilize the arc.
Upon completion of the weld, release the gun trigger switch, raise the welding helmet, and visually examine the weld.
NOTE!
To help you overcome any problems that might arise, you will find useful information in section 4.05 Basic
Welding Techniques.
4.04 Shutdown Procedures
Place the POWER ON/OFF SWITCH in the OFF position.
WARNING
!
After releasing the gun switch, the electrode wire will remain electrically “hot” for several seconds.
4.05 Basic Welding Technique
General
Two different welding processes are covered in this section, with the intention of providing the very basic concepts in using the semiautomatic mode of welding. In this mode, the welding gun is hand-held. The electrode (welding wire) is then fed into a weld puddle and
the arc is shielded by a gas or gas mixture.
Setting of the Power Supply
The settings of the Firepower FP 95 FC requires some practice by the operator in that the welding Power Supply has two control
settings that need to balance. These are the Wire Speed control and the Voltage Control switches. The welding current is determined
by the Wire Speed control (i.e., the current will increase with increased wire speed, resulting in a shorter arc). Slower wire speed will
reduce the current and lengthen the arc. Increasing the welding voltage hardly alters the welding current level, but lengthens the arc.
By decreasing the voltage, a shorter arc is obtained with little change in welding current.
When changing to a different electrode wire diameter, different control settings are required. A thinner electrode wire needs more wire
speed to achieve the same current level.
A satisfactory weld cannot be obtained if the wire speed and voltage switch settings are not adjusted to suit the electrode wire diameter and dimensions of the work piece.
If the wire speed is too high for the welding voltage, “stubbing” will occur as the wire dips into the molten pool and does not melt.
Welding in these conditions normally produces a poor weld due to lack of fusion. If however, the welding voltage is too high, large drops
will form on the end of the electrode wire, causing spatter. The correct setting of voltage and wire speed can be seen in the shape of
the weld deposit and heard by a smooth regular arc sound.

Flux-Cored Arc Welding (FCAW)
This process also known as Open Arc, Innershield, FAB Shield,
etc., is an electric arc welding process which fuses together the
parts to be welded by heating them with an arc between a continuous flux filled electrode wire and the work. Shielding is obtained through decomposition of the flux within the tubular wire.
The process is normally applied semi-automatically; however
the process may be applied automatically or by machine. It is
commonly used to weld large diameter electrodes in the flat and
horizontal position and small electrode diameters in all positions.
The process is used to a lesser degree for welding stainless steel
and for overlay work.

Follow these instructions only after referring to the Safety Instructions and Warnings
chapter of this manual, and the instructions
in the Installation chapter
Check List Before Starting
Wire Feed Speed – 1 to 10
Voltage Range Switch Setting – MIN or MAX
Electrode Wire Stick-out – approx 3/8” (10mm)
4.06 Welding Gun Positions
The welding gun should be held at an angle to the weld joint.
Hold the gun so that the welding seam is viewed at all times.
Always wear the welding helmet with proper filter lenses.
CAUTION
!
The electrode wire is not energized until the gun trigger switch
is depressed. The wire may therefore be placed on the seam or
joint prior to lowering the helmet.
Do not pull the welding gun back when the
arc is established. This will create excessive wire extension (stickout) and make a
very poor weld.
4.07 Establishing the Arc and Making
Before attempting to weld on a finished piece of work, it is
recommended that practice welds be made on a sample metal of
the same material as that of the finished piece.
The easiest MIG welding procedure for the beginner to experiment with, is the flat position. This equipment is capable of flat,
vertical and overhead positions.
For practicing MIG welding, secure some pieces of 16 or 18
gauge (0.06” 1.5mm or 0.08” 2.0mm) mild steel plate 6” x 6”
(150 x 150mm). Use 0.024” (0.6mm) wire.

4.08 Pre-Weld Procedure
1. Check the OPERATION chapter of this manual for details on this equipment.
2. Set the welding voltage range switch at position MIN or MAX.
3. Set the wire feed speed control to about the 2.5 setting. Readjust as necessary.
4. Review standard safe practice procedures in ventilation, eye and face protection, fire, compressed gas and preventative maintenance. See Safety Instructions and Warnings chapter included in this manual.
4.09 Welding Procedure
1. Maintain the tip to work distance (stickout) at 5/16” to 3/8” (8 to 9mm) at all times.
2. For transverse and longitudinal nozzle angles, see section 4.06 Welding Gun Positions.
3. Hold the gun about 3/8” (9mm) from the work, lower the helmet by shaking your head and squeeze the trigger to start the wire
feeding, and establish the arc.
NOTE!
Get in the habit of shaking the helmet down, rather than using the hands. One hand must hold the gun, and
the other is often needed to hold pieces to be tacked or positioned.
4. Make a single down-hand (pulling) stringer weld bead.
5. Practice welding beads. Start at one edge and weld across the plate to the opposite edge.
NOTE!
When the equipment is properly adjusted, a rapidly cracking or hissing sound of the arc is a good indicator
of correct arc length.
6. Practice stopping in the middle of the plate, restarting into the existing weld crater and continuing the weld bead across the
plate.
NOTE!
When the gun trigger is released after welding, the electrode forms a ball on the end. To the new operator, this may
present a problem in obtaining the penetration needed at the start of the next weld. This can be corrected by cutting
the ball off with wire cutters.

SERVICE
5.01 Cleaning of the Unit
Periodically remove the right side panel (after disconnecting the supply cord from the receptacle) and blow out the interior with clean,
dry, compressed air of not more than 25 PSI air pressure. Do not strike any components with the air hose nozzle.
5.02 Cleaning of the Feed Rolls
Clean the wire groove on the feed roll at frequent intervals. This cleaning operation can be done by using a small wire brush. To clean
the wire groove, loosen the pressure device and lift the feedroll pressure arm. Remove all wire from the feedhead. Wipe off the bearing
roll (the “top” roll in the feedhead).
5.03 Basic Troubleshooting
The basic level of troubleshooting is that which can be performed without special equipment or knowledge, and without removing the
covers from the Power Source.
If major components are faulty, then the Power Source should be returned to an Accredited ESAB Service Agent for repair.
1. Porosity
When there is a gas problem the result is usually porosity within the weld metal. Porosity always stems from some contaminant within
the molten weld pool which is in the process of escaping during solidification of the molten metal.
Contaminants range from no gas around the welding arc to dirt on the work piece surface. Porosity can be reduced by checking the
following points:
1. Welding dirty, oily, painted, oxidized or greasy plate.
a. Clean contaminates off the plate.
2. Distance between the MIG torch nozzle and the work piece.
a. Keep the distance between the MIG torch nozzle and the work piece to a minimum.
2. Inconsistent wire feed
Wire feeding problems can be reduced by checking the following points:
1. Wire spool brake is too tight.
a. Feed roller driven by motor in the cabinet will slip.
2. Wire spool brake is too loose.
a. Wire spool can unwind and tangle.
3. Worn or incorrect feed roller size.
a. Use ‘V’ groove drive feed roller matched to the steel wire size you are welding.
4. Misalignment of inlet/outlet guides.
a. Wire will rub against the misaligned guides and reduces wire feedability.
5. Liner blocked with slag.
a. Slag is produced by the wire passing through the feed roller, if excessive pressure is applied to the pressure roller
adjuster. Slag can also be produced by the wire passing through an incorrect feed roller groove shape or size. Slag is
fed into the liner where it accumulates, thus reducing wire feedability.
6. Incorrect or worn contact tip.
a. The contact tip transfers the weld current to the electrode wire. If the hole in the contact tip is too large, then arcing
may occur inside the contact tip resulting in the electrode wire jamming in there. When using soft electrode wire such
as aluminum, the wire may become jammed in the contact tip due to expansion of the wire when heated. A contact
tip designed for soft electrode wires should be used.
7. Poor work lead contact to work piece.
a. If the work lead has a poor electrical contact to the work piece, then the connection point will heat up and result in a
reduction of power at the arc.
8. Bent liner.
a. This will cause friction between the wire and the liner thus reducing wire feedability
