FIREPOWER FP 125,135,165 3.06 Installation of Shielding Gas (GMAW) Process Refer to Figure 3-1. NOTE! 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 por- table mounting arrangement is used, follow the instructions that are provided with it.

FIREPOWER FP 125,135,165 Adjusting Regulator Adjust control knob of regulator to the required flow rate, indicated on gauge dial. (Refer to Figure 3-2 and data charts. Approx. 20 CFH) The gas flow rate should be adequate to cover the weld zone to stop weld porosity. Excessive gas flow rates may cause turbulence and weld porosity.
3.07 Attaching the Gun and Cable Assembly to the Power Source The Firepower FP 125, FP 135, FP 165 are supplied with a 80A MIG gun. The 80A MIG gun is designed with an ergonomic handle and fewer parts to eliminate performance problems. The 80A MIG gun uses standard readily available Firepower consumable parts.
FIREPOWER FP 125,135,165 3.08 Polarity Changeover WARNING ELECTRIC SHOCK CAN KILL! Make certain the machine is unplugged from the power receptacle. Do not plug machine in until told to do so in these instructions As delivered from the factory, the output polarity is set to the polarity which matches the welding wire supplied with the unit. The output terminals are located on the interior panel of the welding power source if you need to change polarity.

FIREPOWER FP 125,135,165 4.07 Welding Gun Positions The welding gun should be held at an angle to the weld joint (see Secondary Adjustment Variables in Section 4.08). Hold the gun so that the welding seam is viewed at all times. Always wear the welding helmet with proper filter lenses.
FIREPOWER FP 125,135,165 4.08 MIG Welding (GMAW) Variables Most of the welding done by all processes is on carbon steel. The following items describe the welding variables in short-arc weld- ing of 24 gauge (0.024”, 0.6mm) to ¼” (6.4mm) mild sheet or plate. The applied techniques and end results in the GMAW process are controlled by these variables.

ESAB FIREPOWER FP-125,135,165 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.
