5. Arahan Operasi

5.1 Kawalan Ke Atasview

Rajah 1: Depan view of the Lincoln Electric Autopro 155S Welder, showing control panel and cable connections.

The front panel of the Autopro 155S features a control knob for adjusting welding current (amperage) and indicator lights for power and thermal overload. Familiarize yourself with these controls before operation.

• Amperage Control Knob: Adjusts the welding current from 30 to 155 amps. Pilih yang sesuai amperage based on the electrode type and material thickness.
• Lampu Petunjuk Kuasa: Illuminates when the welder is powered on.
• Thermal Overload Indicator Light: Illuminates if the machine overheats. If this light comes on, stop welding and allow the unit to cool down.

5.2 Welding Procedure

1. Ensure all safety precautions are observed, including wearing appropriate personal protective equipment (PPE).
2. Sambungkan tanah clamp securely to the workpiece or welding table.
3. Turn on the welder. The power indicator light should illuminate.
4. Laraskan amperage control knob to the desired setting. Refer to electrode manufacturer recommendations for specific settings.
5. Strike an arc by lightly scratching the electrode against the workpiece. Maintain a consistent arc length and travel speed for a quality weld.
6. When finished welding, turn off the welder and allow the workpiece to cool before handling.

6. Penyelenggaraan

Regular maintenance ensures the longevity and optimal performance of your Autopro 155S welder.

• Pembersihan: Periodically clean the exterior of the welder with a dry, soft cloth. Ensure cooling vents are free from dust and debris to prevent overheating. Do not use solvents or abrasive cleaners.
• Pemeriksaan Kabel: Periksa kabel kimpalan, pemegang elektrod dan penutup bumi secara berkalaamp untuk kerosakan, potongan atau sambungan yang longgar. Gantikan komponen yang rosak dengan segera.
• Storan: Simpan mesin kimpal di persekitaran yang bersih dan kering apabila tidak digunakan.

WARNING: Always disconnect the welder from the power source before performing any maintenance or cleaning.

7. Penyelesaian masalah

This section addresses common issues you might encounter with your Autopro 155S welder.
