3. Setup
Proper setup is crucial for safe and effective welding. Follow these steps to prepare your ANDELI ARC-250E welder for operation.
Power Connection:
- Ensure the welder's power switch is in the OFF position.
- The ARC-250E is designed for 200V AC input. Connect the power cord to a suitable 200V power outlet. Note: Attempting to operate the 200V unit on a 110V supply will result in significantly reduced performance and potential damage. Verify your power source matches the welder's requirements.
- The welder is compatible with both 50Hz and 60Hz frequencies.

Welding Cable Connection:
- Connect the ground clamp cable to the negative (-) terminal on the front panel of the welder. Secure the ground clamp to the workpiece, ensuring good electrical contact.
- Connect the MMA holder cable to the positive (+) terminal on the front panel of the welder.
- Insert a suitable welding rod into the MMA holder.
4. Operation
Once the welder is set up, you can begin welding. Always wear appropriate PPE and ensure a safe working environment.
Powering On:
- After connecting the power and welding cables, switch the power button on the rear panel to the 'ON' position.
- The digital display on the front panel will illuminate, indicating the machine is ready.
Adjusting Welding Current:
The welding current can be adjusted using the 'Current' knob on the front panel. The recommended welding current varies depending on the electrode diameter and material thickness.
- For 1.4mm electrodes, adjust the current accordingly.
- For 1.6mm electrodes, adjust the current accordingly.
- The machine can weld plate thicknesses up to 3mm.
- The welder can automatically suggest a welding current based on electrode diameter, or you can manually adjust it to suit your welding habits and specific application.
Advanced Welding Features:
- Hot Start: This feature provides an initial boost of current to help ignite the arc easily, especially with difficult-to-start electrodes.
- Force Adjustment: Allows for fine-tuning of the arc force, which helps prevent the electrode from sticking and improves penetration.
- Anti-sticking Electrode: Automatically reduces the current if the electrode sticks to the workpiece, making it easier to detach and preventing damage to the electrode or machine.
Welding Process:
- Position the ground clamp securely on the workpiece.
- Hold the MMA holder with the electrode close to the workpiece.
- Strike the arc by lightly touching and quickly lifting the electrode from the workpiece.
- Maintain a consistent arc length and travel speed to create a uniform weld bead.
- After welding, turn off the machine and allow it to cool before handling.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your ANDELI ARC-250E welder.
Cleaning:
- Periodically clean the exterior of the welder with a dry, soft cloth.
