3.3 Power Connection

The ARC-200 features automatic voltage detection, allowing it to operate on AC 100~250V, 50~60Hz power supplies. The machine comes with an 8-foot power cord and a 6-50P plug. A 230V to 115V power adapter is included for use with standard 115V outlets.

1. Ensure the welder's power switch is in the OFF position.
2. For 230V operation, plug the machine's 6-50P plug directly into a compatible 230V outlet.
3. For 115V operation, connect the included 230V to 115V power adapter to the machine's plug, then plug the adapter into a 115V outlet.
4. Always ensure the power source meets the welder's requirements and is properly grounded.

3.4 Connecting Welding Cables

Connect the electrode holder and work clamp cables to the appropriate terminals on the front panel of the welder.

1. Connect the electrode holder cable (red connector) to the positive (+) terminal.
2. Connect the work clamp cable (black connector) to the negative (-) terminal.
3. Ensure connections are tight and secure to prevent poor electrical contact and overheating.

4.3 Mode Selection

The ARC-200 supports both Stick Arc and Lift-TIG welding. The machine automatically detects the welding mode based on the connected accessories and operation. Ensure you have the correct torch/holder for your desired process.

4.4 Current Adjustment

Use the 'MIN' to 'MAX' knob on the front panel to adjust the welding current. The digital display will show the selected amperage. The current range is 5-200 Amp for 230V input and 5-145 Amp for 115V input.

4.5 Arc Force Adjustment

The 'ARC FORCE' knob allows you to adjust the arc characteristics. Increasing the arc force can help prevent the electrode from sticking and improve penetration, especially with certain types of electrodes or in specific welding positions. Adjust this setting based on your welding application and electrode type.

4.6 Welding Process (General)

1. Prepare Workpiece: Clean the workpiece thoroughly to remove rust, paint, oil, or other contaminants.
2. Connect Work Clamp: Securely attach the work clamp to the workpiece, ensuring good electrical contact.
3. Insert Electrode: For Stick welding, insert the appropriate electrode into the electrode holder.
4. Set Parameters: Adjust the welding current and arc force according to the electrode type, material thickness, and desired weld.
5. Initiate Arc: For Stick welding, strike the electrode against the workpiece to initiate the arc. For Lift-TIG, touch the tungsten to the workpiece and then lift slightly to initiate a stable arc.
6. Weld: Maintain a consistent arc length and travel speed to create a uniform weld bead.
7. Inspect Weld: After welding, allow the workpiece to cool and inspect the weld for quality.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Amico ARC-200 welder.

• Cleaning: Periodically clean the internal components of the welder using dry, compressed air to remove dust and debris. Ensure the power is disconnected before cleaning.
• Cable Inspection: Regularly inspect all welding cables, connections, and the power cord for cuts, abrasions, or loose connections. Replace damaged cables immediately.
• Ventilation: Ensure the ventilation openings on the welder are clear and unobstructed to prevent overheating.
• Storage: Store the welder in a clean, dry environment, away from excessive dust, moisture, and corrosive materials.

6. Troubleshooting

This section provides solutions to common issues you might encounter with your ARC-200 welder.

The ARC-200 includes built-in protection features for over-voltage, under-voltage, over-current, and overload. If a protection circuit is activated, the machine may temporarily stop welding or display an error code. Allow the machine to reset or cool down before resuming operation.
