2. Safety Information

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

• Eye Protection: Always wear a welding helmet with appropriate shade lenses to protect your eyes from intense light and UV radiation.
• Body Protection: Wear flame-resistant clothing, heavy-duty gloves, and protective footwear to prevent burns and electrical shock.
• Ventilation: Ensure adequate ventilation in your work area to disperse welding fumes, which can be hazardous if inhaled.
• Electrical Safety: Never operate the welder in wet conditions. Ensure all electrical connections are secure and properly grounded. Do not touch live electrical parts.
• Fire Prevention: Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
• Fume Hazards: Avoid inhaling welding fumes. Use a fume extractor or work in a well-ventilated area.
• Children and Bystanders: Keep children and unauthorized personnel away from the welding area.
• Maintenance: Regularly inspect the welder and its accessories for damage. Do not use damaged equipment.

4. Setup

4.1 Wire Spool Installation (Flux Core MIG)

Proper installation of the flux core wire is crucial for smooth operation. Refer to the diagram below for component identification.

1. Open the side panel of the welder to access the wire feed mechanism.
2. Remove the spool lock, washer, spring, and spool spacer from the spindle.
3. Place the flux core wire spool onto the spindle, ensuring it rotates freely.
4. Reinstall the spool spacer, spring, washer, and spool lock, securing the spool in place.
5. Feed the wire through the wire guide and into the wire feed rollers.
6. Close the wire feed roller tension arm and adjust the tension as needed (usually moderate tension to prevent slipping without crushing the wire).
7. Thread the wire through the MIG torch liner until it exits the contact tip.

4.2 Connecting Accessories

• Connect the MIG torch to the appropriate connector on the front panel.
• Connect the ground clamp cable to the negative (-) terminal and attach the clamp to the workpiece.
• For MMA (Stick) welding, connect the electrode holder to the positive (+) terminal and the ground clamp to the negative (-) terminal.
• For Lift TIG welding, connect the TIG torch (not included) to the negative (-) terminal and the ground clamp to the positive (+) terminal. Ensure a gas supply is connected to the TIG torch if using shielded gas.

5. Operating Modes

The HAXIAOER MIG145 offers three primary welding modes: Gasless MIG (Flux Core), Lift TIG, and MMA (Stick) welding. Select the desired mode using the function select button on the control panel.

5.1 Gasless MIG (Flux Core) Welding

This mode uses flux-cored wire, eliminating the need for external shielding gas. It is ideal for outdoor welding and dirty or rusty materials.

1. Ensure the flux core wire is correctly installed (refer to Section 4.1).
2. Select the MIG mode on the control panel.
3. Adjust the wire feed speed and voltage according to the material thickness and wire diameter. The digital display will show the settings.
4. Attach the ground clamp securely to the workpiece.
5. Position the MIG torch at the starting point of the weld.
6. Press the trigger on the MIG torch to begin welding.

5.2 Lift TIG Welding

Lift TIG welding provides precise control and high-quality welds, especially for thinner materials and stainless steel. An additional TIG torch and shielding gas (e.g., Argon) are required for this mode.

1. Connect the TIG torch to the negative (-) terminal and the ground clamp to the positive (+) terminal.
2. Ensure the TIG torch is properly assembled with a tungsten electrode and ceramic cup.
3. Connect the shielding gas cylinder to the TIG torch and set the gas flow rate.
4. Select the TIG mode on the control panel.
5. Adjust the welding current according to the material thickness.
6. Attach the ground clamp securely to the workpiece.
7. Initiate the arc by gently touching the tungsten electrode to the workpiece and then lifting it slightly (Lift Arc).
8. Feed the filler rod manually into the weld puddle.

5.3 MMA (Stick) Welding

MMA welding is suitable for a wide range of materials and thicknesses, often used for heavy fabrication and outdoor repairs.

1. Connect the electrode holder to the positive (+) terminal and the ground clamp to the negative (-) terminal.
2. Insert the appropriate welding electrode (rod) into the electrode holder.
3. Select the MMA mode on the control panel.
4. Adjust the welding current based on the electrode type and diameter, and the material thickness.
5. Attach the ground clamp securely to the workpiece.
6. Strike the electrode against the workpiece to initiate the arc and begin welding.

6. Maintenance

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

• Cleaning: Periodically clean the internal components of the welder using compressed air to remove dust and metal particles. Ensure the machine is unplugged before cleaning.
• Cable Inspection: Inspect all welding cables, torch, and ground clamp for cuts, fraying, or loose connections. Replace damaged components immediately.
• Wire Feed Mechanism: Clean the wire feed rollers and guides regularly to prevent wire feeding issues. Check for wear on the rollers and replace if necessary.
• Contact Tips and Nozzles: Replace worn contact tips and clean welding nozzles to ensure proper wire transfer and gas flow (if applicable).
• Storage: Store the welder in a clean, dry environment, away from excessive dust, moisture, and extreme temperatures.
