2. Informazioni sulla sicurezza

Welding operations involve significant risks. Adherence to safety precautions is paramount to prevent injury or damage. Always follow local safety regulations and guidelines.

• Elettro-shock: Welding current can be lethal. Ensure proper grounding. Do not touch live electrical parts. Wear dry welding gloves.
• Fumi e Gas: La saldatura produce fumi e gas che possono essere pericolosi per la salute. Lavorare in un'area ben ventilata. Utilizzare un sistema di aspirazione dei fumi se necessario.
• Raggi dell'arco: Arc rays can cause eye and skin burns. Always wear a welding helmet with appropriate shade filter and protective clothing.
• Incendio ed esplosione: Le scintille di saldatura e il metallo caldo possono causare incendi. Tenere i materiali infiammabili lontano dall'area di saldatura. Tenere un estintore a portata di mano.
• Ustioni: Hot metal and slag can cause severe burns. Wear protective clothing, gloves, and footwear.
• Posizionamento della macchina: Place the welder on a stable, level surface. Ensure adequate ventilation around the machine to prevent overheating.
• Alimentazione elettrica: Connect the welder to a power supply that matches the machine's requirements. Ensure the power cord is in good condition.

4. Impostazione

Before operating the welder, ensure proper setup:

1. Disimballaggio: Estrarre con cautela la saldatrice e tutti gli accessori dall'imballaggio. Verificare che non vi siano danni dovuti al trasporto.
2. Posizionamento: Position the welder on a stable, non-flammable surface. Ensure at least 30 cm (12 inches) of clear space around the machine for ventilation.
3. Collegamento elettrico: Connect the power cable to a suitable electrical outlet that meets the specifications listed in Section 7. Ensure the power switch on the welder is in the "OFF" position before connecting.
4. Terra Clamp Connessione: Attacca il terreno clamp cavo al terminale negativo (-) sul pannello anteriore della saldatrice. Fissare saldamente il morsetto di terraamp al pezzo in lavorazione o al tavolo di saldatura, garantendo un buon contatto elettrico.
5. Electrode Holder (MMA) / TIG Torch (TIG-Lift) Connection:
   • For MMA welding, connect the electrode holder cable to the positive (+) terminal.
   • For TIG-Lift welding, connect the TIG torch cable to the negative (-) terminal (for DC TIG). If using a TIG torch with a gas valve, connect the gas hose to a suitable inert gas cylinder (e.g., Argon) with a regulator.

5. Istruzioni per l'uso

5.1 Pannello di controllo Sopraview

Fare riferimento alla Figura 1 per la posizione dei seguenti controlli:

• Manopola di regolazione della corrente: Located on the right side of the control panel, this knob adjusts the welding current from 10 A to 250 A. The scale indicates current values and recommended electrode diameters.
• MMA/TIG Selector Switch: A toggle switch to select between MMA (Stick) welding and TIG-Lift welding modes.
• Luci di segnalazione:
  • Indicatore di alimentazione: si illumina quando la macchina è accesa.
  • Thermal Protection Indicator: Illuminates if the machine overheats, indicating that welding should cease until the light extinguishes.
• VRD Indicator: Illuminates when the Voltage Reduction Device is active, indicating reduced open-circuit voltage per una maggiore sicurezza.

5.2 Saldatura MMA (ad elettrodo)

1. Seleziona la modalità MMA: Set the MMA/TIG selector switch to "MMA".
2. Inserire l'elettrodo: Securely insert the appropriate electrode into the electrode holder.
3. Regola corrente: Turn the current adjustment knob to set the desired welding amperage based on the electrode type and diameter, and the material thickness.
4. Accensione: Switch the main power switch to "ON". The power indicator light should illuminate.
5. Arco di attacco: Gently scratch the electrode against the workpiece to initiate the arc. Maintain a consistent arc length.
6. Saldare: Move the electrode steadily along the joint, maintaining the arc and travel speed.

5.3 TIG-Lift DC Welding

1. Selezionare la modalità TIG: Set the MMA/TIG selector switch to "TIG".
2. Prepare TIG Torch: Ensure a sharpened tungsten electrode is correctly installed in the TIG torch. Connect the gas hose to an inert gas supply (e.g., Argon) and set the gas flow rate.
3. Regola corrente: Turn the current adjustment knob to set the desired welding ampera.
4. Accensione: Switch the main power switch to "ON".
5. Initiate Arc (Lift-Arc): Gently touch the tungsten electrode to the workpiece. Lift the torch slightly (1-2 mm) to initiate the arc. The machine will automatically sense the contact and initiate the arc at a low current, then ramp fino alla corrente impostata.
6. Saldare: Maintain a consistent arc length and travel speed, feeding filler rod if necessary.

6. Manutenzione

Una manutenzione regolare garantisce la longevità e le prestazioni ottimali della vostra saldatrice.

• Pulizia: Periodically clean the exterior of the machine with a dry, soft cloth. Use compressed air to blow out dust from the ventilation grilles, ensuring the machine is unplugged before cleaning.
• Ispezione dei cavi: Regularly inspect welding cables, electrode holder, ground clamp, and power cord for cuts, cracks, or damaged insulation. Replace damaged components immediately.
• Connessioni terminali: Ensure all cable connections to the welder terminals are tight and free from corrosion.
• Magazzinaggio: Quando non viene utilizzata, conservare la saldatrice in un ambiente pulito e asciutto, al riparo da polvere e umidità.
