2. Maklumat Keselamatan

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

• Alat Pelindung Diri (PPE): Always wear appropriate PPE, including a welding helmet with proper shade, flame-resistant clothing, welding gloves, and safety shoes. Protect bystanders with welding screens.
• Pengudaraan: Ensure adequate ventilation to remove welding fumes, which can be hazardous. Work in a well-ventilated area or use fume extraction equipment.
• Keselamatan Elektrik: 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.
• Pencegahan Kebakaran: Keep flammable materials away from the welding area. Have a fire extinguisher readily available. Hot metal and sparks can cause fires.
• Sinar Arka: Arc rays can cause eye and skin burns. Never look at the welding arc without proper eye protection.
• Asap dan Gas: Avoid breathing welding fumes and gases. They can be harmful to your health.
• Kawasan Kerja: Pastikan kawasan kerja bersih dan bebas daripada kekusutan. Pastikan tapak kaki stabil.

4. Arahan Persediaan

4.1. Persediaan Awal

1. Unpack the welder and place it on a stable, level surface.
2. Pastikan suis kuasa berada dalam kedudukan 'OFF'.
3. Sambung bumi 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.

3. Turn the 'POWER' switch to the 'ON' position. The 'POWER ON' indicator light should illuminate.

5.2. Menetapkan Parameter Kimpalan

• Tetapan Kuasa: 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.
• Kelajuan wayar: 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. Welding Procedure

1. Pasangkan penutup bumi dengan kukuhamp ke bahan kerja, memastikan sentuhan elektrik yang baik.
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. Lepaskan picu untuk menghentikan kimpalan.
