2. Informació de seguretat

Welding can be hazardous. Always follow safety precautions to prevent injury or damage. Read and understand all safety warnings and instructions before operating the machine.

• Descàrrega elèctrica: Can kill. Do not touch live electrical parts. Wear dry insulating gloves and protective clothing.
• Fums i gasos: Pot ser perillós per a la salut. Mantingueu el cap allunyat dels fums. Utilitzeu la ventilació o l'extracció per eliminar els fums de la zona de respiració.
• Raigs d'arc: Can burn eyes and skin. Wear a welding helmet with a proper shade of filter lens to protect your face and eyes. Wear appropriate eye protection with side shields when not welding.
• Incendi i explosió: Welding can cause fire or explosion. Keep flammables away from welding area. Have a fire extinguisher nearby.
• Parts calentes: Pot causar cremades greus. No toqueu les parts calentes amb les mans nues. Deixeu que l'equip es refredi abans de manipular-lo.
• Soroll: El soroll excessiu pot danyar l'oïda. Feu servir protecció auditiva.

4. Configuració

The Firepower MST 140i is designed for quick setup, allowing you to begin welding promptly. Refer to the Quick Start guide included with your machine for a four-step setup process.

4.1 Connexió d'alimentació

• Ensure the machine is turned off before connecting to power.
• Connect the power cord to a 115VAC, 20 Amp dedicated circuit for optimal performance. An adapter is provided for typical 15 Amp outlets, but note that full potential may not be achieved on a 15 Amp circuit

4.2 Cl mòltamp Connexió

• Connecteu la terra clamp cable to the appropriate terminal on the front panel of the welder.
• Fixeu fermament el clavill de terraamp to the workpiece or a clean, bare metal work surface to ensure a good electrical connection.

4.3 Welding Process Specific Setup

4.3.1 MIG (GMAW/FCAW) Setup

• Open the side panel (refer to Figure 3.4) and install the appropriate welding wire spool.
• Thread the wire through the wire feed mechanism and into the MIG gun liner.
• For gas-shielded MIG welding, connect the gas hose from your shielding gas cylinder (e.g., Argon/CO2 mix) to the gas inlet on the machine and set the flow rate on the regulator.
• For Flux-Cored Arc Welding (FCAW) without gas, ensure the polarity is reversed: the ground clamp should be connected to the positive (+) terminal and the MIG gun to the negative (-) terminal.

4.3.2 Stick (SMAW) Setup

• Connect the electrode holder cable to the appropriate terminal (usually positive for most electrodes).
• Insert the desired stick electrode into the electrode holder.

4.3.3 TIG (GMAW) Setup

• Connect the TIG torch to the appropriate terminal.
• Connect the gas hose from your Argon shielding gas cylinder to the gas inlet on the machine and set the flow rate.
• Ensure you have a TIG torch with a gas valve and a tungsten electrode installed.

5. Instruccions de funcionament

Once the machine is set up, you can begin welding. Always wear appropriate personal protective equipment (PPE) including a welding helmet, gloves, and protective clothing.

5.1 Funcionament general

• Enceneu l'interruptor d'alimentació situat al panell frontal.
• Select the desired welding process (MIG, Stick, or TIG) using the process selector switch.
• Ajusteu el amperage (A) and voltage (V) settings according to the material thickness and welding process. Refer to the welding charts provided on the machine's internal panel or in the full manual.

5.2 MIG (GMAW/FCAW) Welding

• Configuració: The MST 140i provides 140 Amps with 19 Volts at 15% duty cycle. At 104°F, the welding output is 90 Amps with 18.5 Volts at 20% duty cycle.
• Wirefeed Speed: Adjust the wirefeed speed using the dedicated knob (90-390 IPM range).
• Tècnica: Maintain a consistent travel speed and stick-out. For flux-cored wire, ensure correct polarity (ground clamp positive, MIG gun negative) to prevent excessive slag.

5.3 Soldadura amb electrodo electrostàtic (SMAW)

• Configuració: The MST 140i provides 90 Amps with 23 Volts at 15% duty cycle. At 104°F, the welding output is 80 Amps with 23.2 Volts at 35% duty cycle.
• Força de l'arc: Use the Arc Force control to adjust the stiffness of the arc, which helps prevent the electrode from sticking.
• Tècnica: Maintain a short arc length and consistent travel speed.

5.4 TIG (GMAW) Welding

• Configuració: The MST 140i provides 140 Amps with 15.6 Volts at 15% duty cycle. At 104°F, the welding output is 100 Amps with 14 Volts at 20% duty cycle.
• Ascensor TIG: This machine features Lift TIG ignition, where the arc is initiated by lightly touching the tungsten to the workpiece and then lifting it.
• Tècnica: Maintain a consistent arc length and proper torch angle. Use a filler rod if necessary.

6. Manteniment

Regular maintenance ensures the longevity and optimal performance of your Firepower MST 140i welding system.

• Neteja: Periodically clean the internal components of the machine using compressed air to remove dust and debris. Ensure the power is disconnected before cleaning.
• Inspecció del cable: Regularly inspect all welding cables, ground clamps, and torch connections for damage, fraying, or loose connections. Replace damaged components immediately.
• Mecanisme d'alimentació de filferro: Keep the wire feed rollers clean and free of debris. Ensure the tension is correctly set for the wire size being used.
• Consumibles: Replace MIG gun tips, nozzles, and TIG tungsten electrodes as they wear out to maintain weld quality.
