Requirements For Maximum Output - Firepower FP-125 Operating Manual

FIREpOwER Fp-125, 135, 165

3.05 Requirements for Maximum Output

In order to obtain the maximum output capability of the
FirePower FP-125 a branch circuit capable of 40 amperes
at 115 to 125 Volts 60 Hz is required. In order to obtain
the maximum output capability of the FirePower FP-135 a
branch circuit capable of 50 amperes at 115 to 125 Volts
60 Hz is required. In order to obtain the maximum output
capability of the FirePower FP-165 a branch circuit capable
of 30 amperes at 208 to 230 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.
3.06 Installation of Shielding Gas
(GMAW) Process
Refer to Figure 3-1.
Shielding Gas is not required if the unit is using
self-shielded FCAW (flux cored arc welding)
wires.
1. Cylinder Positioning: Chain the cylinder to a wall
or other support to prevent the cylinder from
falling over. If an optional portable mounting ar-
rangement is used, follow the instructions that
are provided with it.
2. Remove Cylinder Cap: Remove the large metal
cap on top of the cylinder by rotating counter
clockwise. Next remove the dust seal.
3. Cracking: Position yourself so the valve is pointed
away from you and quickly open and close the
valve for a burst of gas. This is called "Cracking"
and is done to blow out any foreign matter that
may be lodged in the fitting.
Manual 0-5123
NOTE
KEEP FACE WELL AWAY FROM THE CYLINDER VALVE
DURING "CRACKING". Never "crack" a fuel gas cylinder
valve near other welding works, sparks or open flames.
Ensure that the surrounding area is well ventilated.
4. Fit Regulator/Flowmeter to Cylinders:
Screw the regulator into the appropriate cylinder. The nuts
on the regulator and hose connections are right hand (RH)
threaded and need to be turned in a clockwise direction
in order to tighten. Tighten with a wrench.
Match regulator to cylinder. NEVER CONNECT
a regulator designed for a particular gas or
gases to a cylinder containing any other gas.
5. Attach Supplied Gas Line: Attach supplied gas line
between the regulator output and the desired input at
the rear of the power supply depending on Spool Gun or
MIG Gun use.
