Manuale di istruzioni per la saldatrice a doppio uso Riland MIG-251 GE

1. Introduzione

The Riland MIG-251 GE is an industrial-grade, dual-purpose welding machine designed for both MIG (Metal Inert Gas) and MMA (Manual Metal Arc) welding operations. It incorporates advanced IGBT inverter technology for stable output current and high efficiency. This portable and energy-saving welder is suitable for a wide range of applications, from sheet metal processing to heavy industrial use.

2. Informazioni sulla sicurezza

Always prioritize safety when operating welding equipment. Read and understand all safety warnings and instructions before use. Ensure proper ventilation, wear appropriate personal protective equipment (PPE) including welding helmet, gloves, and protective clothing. Keep a fire extinguisher nearby. Do not operate the machine in wet conditions or near flammable materials.

• Ensure the work area is well-ventilated to reduce dust and smoke inhalation.
• Wear a welding helmet with appropriate shade, welding gloves, and protective clothing.
• Avoid direct exposure to arc light and sparks. The low arc function helps weaken infrared and ultraviolet light.
• Non toccare le parti elettriche sotto tensione.
• Assicurarsi che la macchina sia adeguatamente messa a terra.
• In case of over-temperature or over-current, the machine will automatically stop for protection. Allow it to cool down before resuming operation.

4. Specifiche

5. Impostazione

5.1 Disimballaggio e ispezione

• Estrarre con cautela la saldatrice e tutti gli accessori dall'imballaggio.
• Ispezionare la macchina per verificare eventuali segni di danni durante il trasporto. In caso di danni, contattare immediatamente il fornitore.
• Verify that all standard accessories are present: 1 matching welding gun, 1 ground wire.

5.2 Collegamento di alimentazione

• Assicurarsi che l'interruttore di alimentazione della saldatrice sia in posizione OFF.
• Connect the welder to a 220V ±15% power supply. Ensure the power outlet is properly grounded and can handle the rated input capacity of 5.6KVA.

• La parte posteriore view of the welder (Figure 2) shows the power input cable connection.

5.3 Collegamenti dei cavi di saldatura

• Terra Clamp: Collegare il cl di terraamp cable to the appropriate terminal on the front panel (usually marked with a ground symbol or '-'). Secure the ground clamp al pezzo in lavorazione, garantendo un buon contatto elettrico.
• MIG Welding Gun: Connect the MIG welding gun to the designated connector on the front panel. Ensure it is securely fastened.
• MMA Electrode Holder (if applicable): For MMA welding, connect the electrode holder cable to the positive (+) terminal and the ground clamp al terminale negativo (-).

5.4 Gas Connection (for MIG Gas Shielded Welding)

• For gas-shielded MIG welding, connect your CO2 gas cylinder to the 'GAS IN' port located at the rear of the machine (refer to Figure 2).
• Assicurarsi che tutti i collegamenti del gas siano ben serrati e privi di perdite.
• If performing gasless MIG welding, this step can be skipped as the machine supports it.

5.5 Welding Wire Installation

• Aprire il vano dell'alimentatore del filo.
• Install the appropriate welding wire (0.8mm recommended) onto the spool holder.
• Thread the welding wire through the wire feeder mechanism and into the welding gun liner. Ensure the wire feeds smoothly.

6. Istruzioni per l'uso

6.1 Accensione

• Once all connections are secure, turn the main power switch to the ON position.
• The machine's display (if present) should light up, indicating it is ready for operation.

6.2 Selezione della modalità e regolazione dei parametri

• Select the desired welding mode (MIG or MMA) using the control panel.
• Adjust the welding parameters using the three knobs:
  • Attuale: Controls the welding current (40-90A for both MIG and MMA).
  • Voltage: Controlla il volume di saldaturatage (61V rated output for MIG).
  • Induttanza: Fine-tunes the arc characteristics for MIG welding.
• For beginners, the Riland smart chip offers one-button adjustment and automatic parameter matching to simplify setup.

6.3 Processo di saldatura

• Saldatura MIG:
  • Ensure gas flow is set correctly (if using gas-shielded MIG).
  • Position the welding gun at the starting point of the weld.
  • Press the trigger to initiate the arc and wire feed.
  • Mantenere una velocità di avanzamento e una lunghezza dell'arco costanti per una qualità di saldatura ottimale.
  • The high-quality wire feeding device ensures smooth and non-stop welding.
• Saldatura MMA:
  • Per innescare l'arco, sbattere l'elettrodo contro il pezzo in lavorazione.
  • Mantenere una lunghezza dell'arco e una velocità di spostamento costanti.
  • The machine's stable output current helps in achieving good welding quality.

6.4 Post-Welding

• Release the welding gun trigger or lift the electrode from the workpiece to stop welding.
• Lasciare raffreddare il pezzo prima di maneggiarlo.
• Turn off the gas supply (if used).
• Turn off the main power switch on the welder.

7. Manutenzione
