2. Informació de seguretat

WARNING: Welding can be dangerous. Always follow safety precautions to prevent injury or damage.

• Equips de protecció individual (EPI): Always wear appropriate PPE, including a welding helmet with proper shade, flame-resistant clothing, welding gloves, and safety shoes. Protect bystanders with welding screens.
• Ventilació: Ensure adequate ventilation to remove welding fumes, which can be hazardous. Work in a well-ventilated area or use fume extraction equipment.
• Seguretat elèctrica: Ensure the power supply is correctly rated for the welder (230V). Do not operate in damp conditions. Inspect cables and connections for damage before each use.
• Prevenció d'incendis: Keep flammable materials away from the welding area. Have a fire extinguisher readily available. Hot metal and sparks can cause fires.
• Raigs d'arc: Arc rays can cause eye and skin burns. Never look at the welding arc without proper eye protection.
• Fums i gasos: Avoid breathing welding fumes and gases. They can be harmful to your health.
• Àrea de treball: Mantingueu la zona de treball neta i lliure de trastos. Assegureu-vos d'una base estable.

4. Instruccions de configuració

4.1. Configuració inicial

1. Unpack the welder and place it on a stable, level surface.
2. Ensure the power switch is in the 'OFF' position.
3. Connecteu la terra clamp to the designated terminal on the front panel.
4. Connect the welding torch cable to the 'TORCH' connection point.
5. Install the wire spool (0.9kg gasless or 0.7kg mild steel wire reels only) into the wire feed mechanism, ensuring it feeds smoothly through the guide tube and into the torch liner.
6. Fit the appropriate contact tip to the torch.

4.2. Gasless Mode Setup

The unit is set up ready for gasless mode. For gasless welding, ensure the polarity is set correctly. The flux-cored wire typically requires DC electrode negative (DCEN) polarity. Refer to the polarity diagram inside the wire feed compartment if unsure.

4.3. Gas Mode Setup (Optional)

To switch to gas mode, a Gas Conversion Kit (Model No. 120.802032) is required. Follow these steps:

1. Change the polarity to DC electrode positive (DCEP) for solid wire and shielding gas. Consult the polarity diagram.
2. Connect the supplied gas hose to the welder's gas inlet and to your gas regulator (not supplied) on the gas cylinder (CO2, Argon, or CO2/Argon Mix).
3. Ensure all gas connections are secure and leak-free.
4. Use appropriate solid welding wire for gas welding.

5. Instruccions de funcionament

5.1. Encès

1. Ensure all connections are secure and the work area is safe.
2. Connect the welder to a suitable 230V power supply.
3. Turn the 'POWER' switch to the 'ON' position. The 'POWER ON' indicator light should illuminate.

5.2. Configuració dels paràmetres de soldadura

• Configuració d'energia: The MIGHTYMIG150 has multiple power settings (MIN/MAX, 1/2). Select the appropriate setting based on the thickness of the material being welded. Start with lower settings for thinner materials and increase for thicker materials.
• Velocitat del cable: Adjust the 'WIRE SPEED' dial (1-10) to control the rate at which the welding wire feeds. A good starting point is to match the wire speed to the power setting to achieve a smooth, consistent arc.

5.3. Procediment de soldadura

1. Fixeu fermament el clavill de terraamp a la peça de treball, garantint un bon contacte elèctric.
2. Position the torch nozzle approximately 10-15mm from the workpiece.
3. Press the torch trigger to initiate the arc and wire feed.
4. Maintain a consistent travel speed and torch angle for a uniform weld bead.
5. Deixeu anar el gallet per aturar la soldadura.

6. Manteniment

Un manteniment regular garanteix la longevitat i el funcionament segur del vostre soldador.

• Neteja: Regularly clean the welder, especially the wire feed mechanism, to remove dust and debris. Use compressed air to clear ventilation slots.
• Consell de contacte: Inspect and replace the contact tip regularly as it wears out. A worn tip can lead to poor arc stability and wire feeding issues.
• Revestiment de torxa: Periodically check the torch liner for blockages or wear. A damaged liner can cause wire feeding problems.
• Terra Clamp: Assegureu-vos que la terra clamp is clean and makes good contact with the workpiece.
• cables: Inspect all cables for cuts, abrasions, or damage. Replace damaged cables immediately.
• Emmagatzematge: Guardeu el soldador en un entorn sec i net quan no l'utilitzeu.
