2. Maklumat Keselamatan

Operating welding equipment involves significant risks. Adherence to safety guidelines is paramount to prevent electric shock, burns, fire, and other hazards. Always prioritize your safety and the safety of others in the work area.

2.1 Peralatan Pelindung Diri (PPE)

• Perlindungan Mata: Always wear approved welding goggles or a welding helmet with appropriate shade lenses to protect against intense light, sparks, and debris.
• Perlindungan Tangan: Use heavy-duty, insulated welding gloves to protect hands from heat, sparks, and electrical shock.
• Perlindungan Badan: Wear flame-resistant clothing, such as leather aprons or jackets, to shield skin from sparks and molten metal. Avoid synthetic clothing.
• Perlindungan Kaki: Wear safety footwear to protect against falling objects and electrical hazards.

2.2 Keselamatan Elektrik

• Ensure the welder is connected to a properly grounded power supply with the correct voltage dan ampera seperti yang dinyatakan dalam spesifikasi produk.
• Inspect power cords and cables for damage before each use. Do not use if insulation is frayed or exposed.
• Never operate the welder in wet conditions or with wet hands.
• Putuskan sambungan kuasa sebelum melakukan sebarang penyelenggaraan atau pelarasan.

2.3 Fire and Explosion Hazards

• Keep flammable materials (e.g., fuel, solvents, wood, textiles) away from the welding area.
• Have a fire extinguisher readily available and know how to use it.
• Do not weld on containers that have held flammable substances, even if they appear empty.

2.4 Pengudaraan

• Pastikan pengudaraan yang mencukupi di kawasan kerja untuk menyebarkan asap kimpalan, yang boleh berbahaya jika terhidu.
• If natural ventilation is insufficient, use local exhaust ventilation or respirators.

3.1 Komponen

• Welding Electrodes: Copper tips that conduct current to the workpiece.
• Handle and Trigger: Ergonomic handle for grip and a trigger to initiate the welding cycle.
• Tombol Kawalan Pemasa: Adjusts the duration of the welding current.
• Kabel kuasa: Connects the welder to the electrical supply.
• Label Keselamatan: Important warnings and instructions located on the unit.

4. Persediaan

4.1 Membongkar dan Pemeriksaan

1. Carefully remove the spot welder from its packaging.
2. Inspect the unit for any signs of shipping damage. If damage is found, do not operate the welder and contact your supplier immediately.
3. Pastikan semua komponen yang disenaraikan dalam pembungkusan ada.

4.2 Sambungan Kuasa

• Verify that the power supply matches the voltage and frequency requirements specified on the welder's rating label (e.g., 230V, 50Hz).
• Connect the power cable to a dedicated, grounded electrical outlet. Avoid using extension cords if possible; if necessary, use a heavy-duty, properly rated extension cord.

4.3 Electrode Installation and Adjustment

1. Ensure the welder is disconnected from the power supply.
2. Insert the copper electrodes into their respective holders.
3. Tighten any retaining screws or mechanisms to secure the electrodes firmly.
4. Adjust the electrode gap to suit the thickness of the material to be welded. The electrodes should meet squarely on the workpiece.

5. Arahan Operasi

Sebelum beroperasi, pastikan semua langkah berjaga-jaga keselamatan difahami dan dipatuhi.

5.1 Menghidupkan dan Mematikan

• To power on, connect the welder to the electrical supply. The unit is typically ready for operation once connected.
• To power off, disconnect the welder from the electrical supply.

5.2 Timer Adjustment

• Locate the timer control knob on the side of the welder (refer to Figure 3.2).
• Rotate the knob to set the desired welding time. The optimal time will vary depending on the material type and thickness. Start with shorter times and increase as needed to achieve a strong weld.

5.3 Proses Kimpalan

1. Sediakan Bahan Kerja: Ensure the metal surfaces to be welded are clean, free from rust, paint, oil, or other contaminants. Clean surfaces promote better conductivity and stronger welds.
2. Kedudukan Bahan Kerja: Place the two pieces of metal to be joined between the electrodes. Ensure good contact between the electrodes and the metal, and between the two metal pieces.
3. Activate Welder: Firmly press the trigger on the handle. The electrodes will clamp the workpiece, and the welding current will flow for the duration set by the timer.
4. Pencetus Lepaskan: Once the timer cycle completes, release the trigger. Allow the weld to cool slightly before removing the workpiece.
5. Periksa Kimpalan: Visually inspect the spot weld for proper formation and strength. Adjust timer settings or electrode pressure if necessary.

5.4 Material Thickness

The SR122 is suitable for welding various gauges of sheet metal. Always test on scrap material of similar thickness to determine optimal timer settings before welding your final workpiece.

6. Penyelenggaraan

Regular maintenance ensures the longevity and safe operation of your spot welder. Always disconnect the power supply before performing any maintenance.

6.1 Penjagaan Elektrod

• Pembersihan: Periodically clean the electrode tips to remove any buildup of metal or oxides. A file or abrasive pad can be used. Clean tips ensure good electrical contact and consistent welds.
• Penggantian: Electrodes will wear down over time. Replace them when they become too short or severely pitted to maintain weld quality.

6.2 Pembersihan dan Pemeriksaan Am

• Wipe down the exterior of the welder with a clean, dry cloth.
• Inspect the power cable and all connections for signs of wear, cuts, or damage. Replace damaged components immediately.
• Pastikan bukaan pengudaraan bersih daripada habuk dan serpihan untuk mengelakkan terlalu panas.

6.3 Penyimpanan

• Store the welder in a clean, dry, and secure location, away from moisture and extreme temperatures.
• Jauhkan daripada kanak-kanak dan kakitangan yang tidak dibenarkan.
