1. Important Safety Information
Read and understand all safety warnings and instructions before operating this welding machine. Failure to follow these instructions may result in electric shock, fire, serious injury, or death. Keep this manual for future reference.
- Electric Shock: Welding current can kill. Do not touch live electrical parts. Wear dry welding gloves and protective clothing. Ensure the work area is dry and well-insulated.
- Fumes and Gases: Welding produces fumes and gases that can be hazardous to your health. Work in a well-ventilated area. Use an exhaust fan or fume extractor if necessary.
- Arc Rays: Arc rays can burn eyes and skin. Wear a welding helmet with a proper shade filter and protective clothing. Protect bystanders with non-reflective screens.
- Fire and Explosion: Welding sparks and hot metal can cause fire or explosions. Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
- Burns: Hot metal and electrodes can cause severe burns. Do not touch hot parts with bare hands. Allow welded materials to cool before handling.
- Personal Protective Equipment (PPE): Always wear appropriate PPE, including a welding helmet, safety glasses, welding gloves, protective clothing, and safety shoes.

5. Setup
5.1 General Setup
- Placement: Place the welding machine on a stable, level surface in a well-ventilated area, away from flammable materials.
- Power Connection: Ensure the machine is switched off. Connect the power cord to a suitable 220-240V power outlet with appropriate circuit protection.
- Grounding: Always ensure the workpiece is properly grounded.
5.2 MIG (Gasless) Setup
- Open Wire Compartment: Lift the top cover of the welder to access the wire spool holder and feed mechanism (refer to Figure 1).
- Install Wire Spool: Place the flux-cored wire spool onto the spool holder. Ensure it rotates freely.
- Feed Wire: Guide the wire through the wire feed mechanism rollers. Ensure the wire is seated correctly in the groove corresponding to its diameter (0.8mm or 1.0mm). Close the pressure arm to secure the wire.
- Connect MIG Torch: Connect the MIG torch to the appropriate connector on the front panel of the welder.
- Install Nozzle: Ensure a 1.0mm nozzle (or appropriate for your wire) is securely installed on the MIG torch.
- Purge Wire: With the machine powered on and in MIG mode, press the torch trigger to feed the wire through the torch liner until it emerges from the nozzle. Cut off any bent wire.
- Connect Ground Clamp: Attach the ground clamp cable to the negative (-) terminal on the welder and securely clamp it to the workpiece, ensuring good electrical contact.
5.3 MMA (Electrode) Setup
- Connect Electrode Holder: Connect the electrode holder cable to the positive (+) terminal on the welder.
- Connect Ground Clamp: Connect the ground clamp cable to the negative (-) terminal on the welder and securely clamp it to the workpiece, ensuring good electrical contact.
- Insert Electrode: Insert the desired electrode into the electrode holder. Ensure it is held firmly.
6. Operating Instructions
6.1 MIG (Gasless) Welding
- Power On: Switch on the welding machine.
- Select Mode: Set the machine to MIG mode.
- Adjust Settings: Set the welding current and wire feed speed according to the wire diameter, material thickness, and desired weld. Start with recommended settings and adjust as needed.
- Wear PPE: Put on your welding helmet, gloves, and other protective gear.
- Welding: Position the torch nozzle close to the workpiece. Press the trigger to start the arc and feed the wire. Maintain a consistent travel speed and torch angle.
- Stop Welding: Release the trigger to stop the arc.
6.2 MMA (Electrode) Welding
- Power On: Switch on the welding machine.
- Select Mode: Set the machine to MMA mode.
- Adjust Settings: Set the welding current based on the electrode type and diameter, and the material thickness.
- Wear PPE: Put on your welding helmet, gloves, and other protective gear.
- Strike Arc: Lightly tap or scratch the electrode against the workpiece to strike an arc. Lift the electrode slightly to maintain the arc.
- Welding: Maintain a consistent arc length and travel speed.
- Stop Welding: Pull the electrode away from the workpiece to break the arc.
7. Maintenance
Regular maintenance ensures the longevity and safe operation of your welding machine. Always disconnect the machine from the power supply before performing any maintenance.
- Cleaning: Periodically clean the inside of the machine with compressed air to remove dust and metal particles. Clean the wire feed rollers and torch liner to prevent wire feeding issues.
