4. Setup and Installation
4.1 Power Connection
The HANSNOK MIG-140 supports dual voltage input (110V/220V). Ensure the power source matches the machine's requirements and use the appropriate adapter if necessary.
- Connect the power cable to the fixed power connector on the rear panel.
- Plug the power cable into a suitable grounded electrical outlet.
4.2 Wire Installation (MIG/Flux Core)
For Flux Core MIG welding, install the welding wire spool as follows:

- Open the side panel of the welder to access the wire feeder compartment.
- Place the welding wire spool onto the damped disc shaft. Ensure it rotates freely.
- Feed the welding wire through the wire feeder mechanism, ensuring it is properly seated in the drive rollers.
- Close the wire feeder tension arm and adjust the tension as needed.
- Connect the MIG welding gun to its designated port on the front panel.
- Press the trigger on the welding gun to feed the wire through the liner and out of the contact tip. Ensure the contact tip is removed during this process to prevent wire jamming.
This Flux Core Welder fits .030" (0.8mm) & .035" (1.0mm) flux core wire.
4.3 Connecting Welding Accessories
- Work Clamp (Ground Clamp): Connect the work clamp cable to the appropriate electrode terminal (positive or negative, depending on the welding process and polarity requirements). Securely attach the clamp to the workpiece or welding table, ensuring good electrical contact.
- Electrode Holder (Stick Welding): For Stick (MMA) welding, connect the electrode holder cable to the appropriate electrode terminal. Insert the welding electrode into the holder.
- Lift TIG Torch (Not Included): If performing Lift TIG welding, connect your compatible Lift TIG torch to the appropriate terminal. Note that a Lift TIG torch is not included with this machine.
5. Operating Instructions
The HANSNOK MIG-140 offers three welding modes: MIG (Flux Core), Lift TIG, and Stick (MMA).

5.1 Mode Selection and Parameter Adjustment
The intelligent LED screen allows for easy reading and adjustment of output current parameters. Use the amperage setting knob to fine-tune your welding current.
5.2 MIG Welding (Flux Core)
- Ensure flux core wire is correctly installed and the MIG gun is connected.
- Set the machine to MIG mode.
- Adjust the amperage using the knob according to the wire diameter and material thickness. The machine features synergy, which helps optimize settings.
- Begin welding, maintaining a consistent travel speed and arc length.
5.3 Stick Welding (MMA)
- Connect the electrode holder and work clamp with appropriate polarity for your chosen electrode.
- Insert an E6013 rod (or other compatible rod) into the electrode holder.
- Set the machine to MMA mode.
- Adjust the amperage based on the electrode diameter and material thickness.
- Strike an arc and maintain a steady arc length and travel speed.
5.4 Lift TIG Welding
- Connect a compatible Lift TIG torch (not included) and work clamp.
- Ensure a tungsten electrode is properly installed in the torch.
- Set the machine to Lift TIG mode.
- Adjust the amperage.
- Initiate the arc by gently touching the tungsten to the workpiece and lifting slightly.

| Problem | Possible Cause | Solution |
|---|---|---|
| Machine does not power on. | No power supply; faulty power cable; internal fuse blown. | Check power outlet and cable connections. Ensure power button is ON. Consult a qualified technician if fuse is suspected. |
| No welding arc. | Loose connections; incorrect mode selection; faulty electrode/wire; insufficient ground. | Verify all cable connections (work clamp, welding gun/electrode holder). Confirm correct welding mode. Check electrode/wire condition. Ensure good ground contact. |
| Poor weld quality (e.g., excessive spatter, weak penetration). | Incorrect amperage/voltage settings; improper travel speed/arc length; contaminated workpiece. | Adjust welding parameters according to material and wire/electrode type. Practice maintaining consistent technique. Clean workpiece thoroughly before welding. |
| Overheat indicator active. | Exceeded duty cycle; blocked cooling vents; high ambient temperature. | Allow the machine to cool down. Ensure cooling vents are clear. Operate in a well-ventilated area. |
