3. Setup and Installation
Proper setup is crucial for safe and effective welding. Follow these steps carefully.
3.1 Power Connection
- Ensure the welder's power switch is in the "OFF" position.
- Connect the power cord to a suitable 110V or 220V power outlet. The machine is designed for dual voltage input.
- Verify that the power source meets the welder's requirements.
3.2 Wire Spool Installation (MIG/Flux Core)
- Open the side panel of the welder to access the wire feed mechanism.
- Place the wire spool onto the spool holder. Ensure it rotates freely.
- Thread the welding wire through the guide tube and into the drive roller groove.
- Close the drive roller tension arm and adjust the tension knob. The tension should be sufficient to feed the wire without slipping, but not so tight as to deform the wire.
- Ensure the correct drive roller size (e.g., 0.8mm, 1.0mm) is selected for your wire diameter.

Figure 6: Wire Feeding Mechanism - Shows the process of installing welding wire and ensuring smooth operation through the drive rollers.
3.3 Torch and Ground Clamp Connection
- Connect the MIG torch to the appropriate connector on the front panel. Ensure it is securely tightened.
- Connect the ground clamp cable to the designated terminal (usually negative for MIG/Flux Core, positive for Stick).
- Attach the ground clamp firmly to the workpiece or welding table, ensuring good electrical contact.
3.4 Gas Connection (for MIG Gas Welding)
- Connect one end of the gas hose to the gas inlet on the rear of the welder.
- Connect the other end of the gas hose to your gas cylinder regulator.
- Ensure all connections are tight to prevent gas leaks. Open the gas cylinder valve slowly.
4. Operating Instructions
The HZXVOGEN MIG250DP offers multiple welding modes. Select the appropriate mode and adjust parameters according to your welding task.
