2. Informazioni sulla sicurezza

Welding operations involve inherent risks. It is crucial to follow all safety guidelines to prevent injury or damage to equipment. Always wear appropriate Personal Protective Equipment (PPE), including welding helmet, gloves, protective clothing, and safety shoes.

• Elettro-shock: Can kill. Do not touch live electrical parts. Insulate yourself from work and ground.
• Fumi e Gas: Può essere pericoloso per la salute. Tenere la testa lontana dai fumi. Utilizzare un sistema di ventilazione o di aspirazione per rimuovere i fumi dalla zona in cui si respira.
• Raggi dell'arco: Può causare ustioni agli occhi e alla pelle. Indossare un casco da saldatura con un filtro di protezione adeguato e indumenti protettivi.
• Incendio ed esplosione: Welding can cause fire or explosion. Keep combustibles away from the work area. Have a fire extinguisher readily available.
• Parti calde: Può causare gravi ustioni. Lasciare raffreddare l'apparecchiatura prima di toccarla.
• Rumore: Il rumore eccessivo può danneggiare l'udito. Indossare protezioni acustiche.
• Parti mobili: Can cause injury. Keep clear of moving parts such as wire feed rolls.

Always read and understand the entire safety section of this manual before operating the welding machine. Ensure the work area is well-ventilated and free from flammable materials.

3. Impostazione

Proper setup is essential for safe and efficient operation of your Esab Rustler EM 300i welding machine. Follow these steps carefully:

3.1 Disimballaggio e ispezione

• Estrarre con cautela la saldatrice e tutti gli accessori dall'imballaggio.
• Inspect the machine for any signs of shipping damage. Report any damage to your supplier immediately.
• Verificare che tutti i componenti elencati nella lista di imballaggio siano presenti.

3.2 Collegamento di alimentazione

The Rustler EM 300i supports both single-phase 220V and three-phase 220/380V power inputs. Ensure the power supply matches the machine's requirements and that the circuit is adequately protected.

• Connect the power cable to a suitable power outlet. Consult a qualified electrician if you are unsure about the correct connection for three-phase power.
• Ensure the main power switch on the machine is in the "OFF" position before connecting to power.

3.3 Wire Feeder Setup (MIG/MAG)

The machine features an integrated 2-roller wire feeder.

• Aprire il pannello laterale della macchina per accedere al vano della bobina del filo.
• Mount the appropriate welding wire spool onto the spindle. Ensure the wire unwinds smoothly.
• Thread the wire through the guide tube and into the wire feeder rollers.
• Adjust the tension of the wire feeder rollers according to the wire diameter and type.
• Chiudere bene il pannello laterale.

3.4 Collegamento gas (MIG/MAG)

For MIG/MAG welding, a shielding gas cylinder is required.

• Connect the gas hose from the machine to the pressure regulator on the gas cylinder.
• Assicurarsi che tutti i collegamenti siano ben serrati per evitare perdite di gas.
• Aprire lentamente la valvola della bombola del gas.

3.5 Terreno Clamp and Torch Connection

• Collegare il cl di terraamp cable to the appropriate terminal on the machine.
• Fissare saldamente il cl di terraamp al pezzo in lavorazione, garantendo un buon contatto elettrico.
• Connect the welding torch (MIG/MAG or MMA electrode holder) to its respective connection point on the front panel.

  • 4T (Quattro tocchi): Press and release to start; press and release again to stop. Ideal for long welds.
• Creep Start: Provides a slow wire feed start to prevent wire stubbing.
• Bruciatura posteriore: Controls the length of wire extending from the torch nozzle after welding stops.
• Crater Fill: Gradually reduces current at the end of a weld to fill the crater and prevent cracking.
• Pre/Post Gas Flow: Controls the gas flow before and after welding to protect the weld puddle.
