6.2. Lift TIG Welding Setup

Note: A TIG torch (WP-17V type) must be purchased separately.

1. Ensure the welder is turned off and unplugged.
2. Connect the ground clamp cable to the positive (+) output terminal of the welding machine.
3. Securely attach the ground clamp to the workpiece.
4. Connect the TIG torch cable to the negative (-) output terminal of the welding machine.
5. Ensure the TIG torch is equipped with a suitable tungsten electrode.
6. Plug in the welder and turn on the power switch.

7. Operating Instructions

7.1. MMA (Stick) Welding

1. After setup, select the appropriate current using the Current Knob based on the electrode diameter and material thickness (refer to the Welding Parameters table below).
2. Strike the arc by lightly touching the electrode to the workpiece and quickly lifting it slightly to establish a stable arc.
3. Maintain a consistent arc length and travel speed for a smooth weld bead.
4. The Hot Start function assists in easy arc ignition, and Anti-Stick prevents the electrode from fusing to the workpiece.

7.2. Lift TIG Welding

1. After setup, select the appropriate current using the Current Knob.
2. Gently touch the tungsten electrode to the workpiece to initiate the arc (Lift TIG).
3. Lift the torch slightly to establish the arc and begin welding.
4. Feed filler rod into the weld puddle as needed.

8. Maintenance

Regular maintenance ensures the longevity and optimal performance of your welder.

• Cleaning: Periodically clean the machine's exterior and ventilation openings to prevent dust and debris buildup. Use compressed air to clear internal components if necessary, ensuring the machine is unplugged.
• Cable Inspection: Regularly inspect all cables (power, electrode, ground) for cuts, fraying, or damaged insulation. Replace damaged cables immediately.
• Terminal Check: Ensure all connections and terminals are tight and free from corrosion.
• Storage: Store the welder in a dry, clean environment, away from excessive dust, moisture, and extreme temperatures.

9. Troubleshooting

If you encounter issues with your FEIFANKE ARC140 welder, refer to the following common troubleshooting steps:

• No Power: Check the power cable connection, wall outlet, and ensure the power switch is ON. Verify the circuit breaker has not tripped.
• No Arc: Ensure the ground clamp is securely attached to the workpiece and the electrode holder has a good connection to the electrode. Check for proper current settings.
• Weak/Unstable Arc: Adjust the welding current. Ensure the electrode is dry and of the correct type and size for the material. Check for proper arc length.
• Overheating (Warning Light ON): The machine has activated its thermal protection. Allow the welder to cool down. Ensure ventilation openings are clear and the cooling fan is operating. Reduce the duty cycle or welding current.
• Electrode Sticking: Increase the welding current. Ensure the Anti-Stick function is active. Practice striking the arc correctly.

If the problem persists after following these steps, please contact customer support.
