5. Impostazione
Follow these steps to set up your DEKO 140A Inverter Welder:
- Preparare l'area di lavoro: Ensure the welding area is clean, dry, and well-ventilated. Remove all flammable materials.
- Collegare la Terra Clamp: Attacca il terreno clamp cable to the negative terminal (-) on the welder. Securely attach the ground clamp to the workpiece or a sturdy metal workbench that is electrically connected to the workpiece. Ensure good electrical contact.
- Collegare il portaelettrodo: Attach the electrode holder cable to the positive terminal (+) on the welder. Insert the welding electrode into the electrode holder.
- Connetti alimentazione: Plug the power cable into a suitable 220V power outlet. Ensure the power switch on the welder is in the OFF position before plugging it in.
- Turn On the Welder: Flip the power switch to the ON position. The Power Light should illuminate, and the digital display will show the current setting.
- Regola corrente: Use the Current Adjustment Knob to set the desired welding amperage based on the electrode size and material thickness. Refer to the "Welding Parameters" section for guidance.
6. Istruzioni per l'uso
6.1. Basic Welding Procedure
- Indossare dispositivi di protezione: Always wear a welding helmet, gloves, and appropriate protective clothing.
- Preparare il pezzo da lavorare: Clean the welding area on the workpiece to remove rust, paint, or grease.
- Crea un arco: Gently tap or scratch the electrode against the workpiece to initiate the arc. The Hot Start feature assists in easier arc ignition.
- Mantenere la lunghezza dell'arco: Keep a consistent arc length, typically equal to the electrode's diameter.
- Move the Electrode: Move the electrode steadily along the joint, maintaining a consistent travel speed and angle. The Arc Force feature helps maintain a stable arc.
- Prevenire l'incollaggio: If the electrode sticks, the Anti-Stick function will reduce the current to help free it.
- Saldatura di finitura: Lift the electrode away from the workpiece to break the arc. Allow the weld to cool before cleaning.
6.2. Caratteristiche principali
- Avvio a caldo: Provides an initial surge of current to make arc striking easier, especially with difficult-to-start electrodes.

- Antiaderente: Automatically reduces the welding current if the electrode sticks to the workpiece, preventing overheating and making it easier to detach the electrode.
- Arcoforza: Increases the current when the arc length becomes too short, preventing the arc from extinguishing and ensuring a stable weld.
