2. Safety Information

Always prioritize safety when operating welding equipment. Failure to follow safety precautions can result in serious injury or death.

• Electric Shock: Welding current can kill. Do not touch live electrical parts. Wear dry welding gloves and protective clothing.
• Fumes and Gases: Welding produces fumes and gases that can be hazardous to your health. Work in a well-ventilated area or use a fume extractor.
• Arc Rays: Arc rays can burn eyes and skin. Wear a welding helmet with appropriate shade lenses and protective clothing.
• Fire and Explosion: Welding sparks and hot metal can cause fires. Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
• Hot Parts: Welded parts and equipment can be hot. Allow them to cool before handling or wear appropriate heat-resistant gloves.
• Magnetic Fields: Welding current creates electromagnetic fields that may interfere with pacemakers or other electronic devices. Consult your doctor before welding.

4. Setup Instructions

4.1 Power Connection

Ensure the welding machine is connected to a suitable power supply. This machine supports dual voltage operation (110V and 220V).

4.2 Ground Clamp Connection

Connect the ground clamp cable to the appropriate terminal on the front panel of the welder. Securely attach the ground clamp to the workpiece or welding table to ensure a good electrical connection.

4.3 Welding Wire Installation (MIG/Flux-Cored)

1. Open the side panel of the welding machine to access the wire feeder compartment.
2. Place the 2lb flux-cored welding wire spool onto the spool holder.
3. Thread the welding wire through the wire feed mechanism and into the MIG torch liner.
4. Close the side panel.

4.4 Torch and Electrode Connections

• MIG Welding: Connect the MIG torch to the designated connector on the front panel.
• Lift TIG Welding: Connect the Lift TIG torch to its respective connector.
• Stick (MMA) Welding: Connect the electrode holder to the positive (+) terminal and the ground clamp to the negative (-) terminal for most common electrodes. Refer to electrode manufacturer specifications for polarity.

5. Operating Modes and Settings

The ANDELI MIG-135PLUS offers multiple welding processes and control options, displayed on a large LED screen for clear visibility.

5.1 Welding Processes

• SYN MIG Welding (Synergic MIG): Automatic matching of current and voltage, ideal for beginners.
• MAN MIG Welding (Manual MIG): Separate regulation of current and voltage, suitable for experienced professionals.
• FLUX MMA Welding (Stick/SMAW): Uses flux-cored electrodes (1.6/2.0/3.2mm rods are available).
• LIFT TIG Welding: Provides powerful performance and easy welding for precise applications.

5.2 Control Modes

• Automatic Mode: The current and voltage are automatically matched, requiring no manual adjustment. Recommended for beginners.
• Adjustment Mode: Current and voltage can be controlled separately and precisely adjusted. Recommended for skilled workers.

5.3 2T/4T Settings

These settings control the torch trigger behavior, adapting to different welding scenarios.

• 2T (Two-Touch): Keep pressing the switch to dispense the welding wire; release the switch to stop.
• 4T (Four-Touch): Press the switch once to automatically continue dispensing the welding wire; press it again to stop dispensing the welding wire.

6. Material Suitability

This welding machine is capable of welding multiple metal materials together, including but not limited to:

• Square Pipe
• Metal Cage
• Galvanized Sheet
• Mild Steel
• Cast Iron
• Stainless Steel

8. Troubleshooting

This section addresses common issues you might encounter during operation.

• No Power: Check the power cord connection, circuit breaker, and ensure the machine is switched on. Verify the input voltage matches the machine's requirements (110V or 220V).
• Poor Arc Start/Unstable Arc: Ensure proper grounding of the workpiece. Check for correct welding parameters (current, voltage, wire feed speed). Clean the contact tip and ensure it's the correct size for your wire. For Stick welding, ensure electrodes are dry and suitable for the material.
• Wire Feeding Issues: Check the wire spool installation and ensure the wire is not tangled. Verify the wire feed roller tension is appropriate – too loose or too tight can cause issues. Inspect the MIG torch liner for blockages or damage.
• Overheating: If the machine stops due to overheating, allow it to cool down. Ensure proper ventilation around the machine and that cooling fans are not obstructed. Reduce the duty cycle or welding current if continuously overheating.
• No Gas Flow (if using gas for MIG/TIG): Ensure the gas cylinder is open and has sufficient gas. Check gas hose connections for leaks or kinks. Verify the gas regulator is set to the correct flow rate.

9. Maintenance

Regular maintenance ensures the longevity and optimal performance of your welding machine.

• Cleaning: Regularly clean the machine's exterior and ventilation openings to prevent dust and debris buildup. Use compressed air to blow out internal components periodically, ensuring the machine is unplugged.
• Cable Inspection: Inspect welding cables, torch, and ground clamp for any signs of wear, cuts, or damage. Replace damaged components immediately.
• Contact Tip and Nozzle: For MIG welding, regularly clean or replace the contact tip and gas nozzle to ensure consistent wire feeding and gas shielding.
• Wire Feed Rollers: Keep the wire feed rollers clean and free of debris. Ensure they are correctly sized for your welding wire.
• Protective Cover: Keep the transparent protective cover over the control panel clean to maintain visibility and protect the display from damage.

10. User Tips

• Dual Voltage Advantage: The MIG-135PLUS is designed to operate on both 110V and 220V power supplies, offering flexibility for different workshop or job site conditions. Ensure you select the correct input voltage setting if applicable, or the machine will auto-detect.
• Start with Automatic Mode: If you are new to welding or to this machine, begin with the Automatic (Synergic) control mode for MIG welding. This mode simplifies parameter setup by automatically matching current and voltage, allowing you to focus on technique.
• Practice on Scrap Material: Before working on your main project, always practice on scrap pieces of the same material and thickness to fine-tune your settings and technique.
• Proper Ventilation: Always ensure adequate ventilation to disperse welding fumes, even for gasless flux-cored welding.

11. Warranty and Support

The ANDELI MIG-135PLUS Welding Machine comes with a 2-Year Warranty. For warranty claims, technical support, or service inquiries, please contact your retailer or the official ANDELI support channels. Keep your proof of purchase for warranty validation.
