Riland MIG-251 GE Dual-Purpose Welder Instruction Manual

1. Einleitung

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. Sicherheitshinweise

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.
• Berühren Sie keine stromführenden Teile.
• Stellen Sie sicher, dass die Maschine ordnungsgemäß geerdet ist.
• In case of over-temperature or over-current, the machine will automatically stop for protection. Allow it to cool down before resuming operation.

5. Einrichtung

5.1 Auspacken und Prüfen

• Nehmen Sie das Schweißgerät und sämtliches Zubehör vorsichtig aus der Verpackung.
• Inspect the machine for any signs of damage during transit. If damaged, contact your supplier immediately.
• Verify that all standard accessories are present: 1 matching welding gun, 1 ground wire.

5.2 Stromanschluss

• Stellen Sie sicher, dass sich der Netzschalter am Schweißgerät in der Position AUS befindet.
• 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.

• Das Heck view of the welder (Figure 2) shows the power input cable connection.

5.3 Schweißkabelverbindungen

• Boden-Clamp: Verbinden Sie die Erdungsklemmeamp cable to the appropriate terminal on the front panel (usually marked with a ground symbol or '-'). Secure the ground clamp zum Werkstück, um einen guten elektrischen Kontakt zu gewährleisten.
• 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 an den Minuspol (-).

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).
• Ensure all gas connections are tight and leak-free.
• If performing gasless MIG welding, this step can be skipped as the machine supports it.

5.5 Welding Wire Installation

• Öffnen Sie das Drahtzufuhrfach.
• 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. Bedienungsanleitung

6.1 Einschalten

• 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 Modusauswahl und Parametereinstellung

• Select the desired welding mode (MIG or MMA) using the control panel.
• Adjust the welding parameters using the three knobs:
  • Aktuell: Controls the welding current (40-90A for both MIG and MMA).
  • Bandtage: Controls the welding voltage (61V rated output for MIG).
  • Induktivität: 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 Schweißverfahren

• MIG-Schweißen:
  • 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.
  • Für eine optimale Schweißqualität eine gleichbleibende Schweißgeschwindigkeit und Lichtbogenlänge einhalten.
  • The high-quality wire feeding device ensures smooth and non-stop welding.
• MMA-Schweißen:
  • Durch Anschlagen der Elektrode am Werkstück wird der Lichtbogen gezündet.
  • Gleichmäßige Bogenlänge und Fahrgeschwindigkeit beibehalten.
  • 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.
• Das Werkstück vor der Weiterverarbeitung abkühlen lassen.
• Turn off the gas supply (if used).
• Turn off the main power switch on the welder.

7. Wartung
