2. Informazioni sulla sicurezza

WARNING: Welding can be dangerous. Protect yourself and others from serious injury or death. Read and understand all safety information provided in this manual and on the equipment labels.

• La scossa elettrica può uccidere: Non toccare parti elettriche sotto tensione. Indossare guanti isolanti asciutti e indumenti protettivi. Isolarsi dal lavoro e dalla terra.
• Fumi e gas possono essere pericolosi: Keep your head out of the fumes. Use ventilation or exhaust to remove fumes and gases from the breathing zone and general area.
• Welding Rays Can Burn Eyes and Skin: Wear a welding helmet with a proper shade of filter to protect your face and eyes when welding or watching. Wear appropriate safety glasses with side shields. Wear protective clothing made from durable, flame-resistant material.
• Rischio di incendio ed esplosione: Remove all flammables within 35 feet (10.7 m) of the welding operation. Have a fire extinguisher nearby.
• Le parti calde possono causare gravi ustioni: Non toccare le parti calde a mani nude. Lasciare raffreddare prima di maneggiarle.
• I campi magnetici possono influenzare i pacemaker: Consultare il medico prima di utilizzare l'attrezzatura per la saldatura.

Always ensure the work area is clean, dry, and well-ventilated. Disconnect power before servicing.

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. Seleziona quello appropriato ampmedia in base al tipo di elettrodo e allo spessore del materiale.
• Indicatore luminoso di alimentazione: 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 Procedura di saldatura

1. Ensure all safety precautions are observed, including wearing appropriate personal protective equipment (PPE).
2. Collegare il cl di terraamp saldamente al pezzo in lavorazione o al tavolo di saldatura.
3. Turn on the welder. The power indicator light should illuminate.
4. Regolare il 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. Manutenzione

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

• Pulizia: 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.
• Ispezione dei cavi: Ispezionare regolarmente i cavi di saldatura, il portaelettrodo e il cavo di terraamp per danni, tagli o collegamenti allentati. Sostituire immediatamente i componenti danneggiati.
• Magazzinaggio: Quando non viene utilizzata, conservare la saldatrice in un ambiente pulito e asciutto.

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

7. Risoluzione Dei Problemi

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

7.1 Nessun potere

• Controllare la connessione di alimentazione: Ensure the input cable is securely plugged into a live 230V outlet.
• Controllare l'interruttore automatico: Verificare che l'interruttore automatico della presa non sia scattato.
• Inspect Input Cable: Look for any visible damage to the input cable.

7.2 Welder Overheats (Thermal Overload Light On)

• Consenti raffreddamento: Stop welding and allow the machine to cool down. The thermal overload light will turn off when it's safe to resume.
• Controllare la ventilazione: Ensure cooling vents are not blocked and the welder has adequate airflow.
• Reduce Duty Cycle: Avoid continuous welding for extended periods.
