6. Setup

6.1 General Setup

1. Ensure the welding machine is placed on a stable, level surface with adequate ventilation.
2. Connect the input power cable (6) to a suitable 220V power outlet.
3. Turn on the Power Switch (5) located at the rear of the machine. The LED Digital Display (1) will illuminate.

6.2 MMA/ARC (Stick) Welding Setup

1. Connect the ground clamp cable to the Negative Output Terminal (4) of the welder.
2. Connect the electrode holder cable to the Positive Output Terminal (3) of the welder.
3. Securely attach the ground clamp to the workpiece or welding table, ensuring good electrical contact.
4. Insert the appropriate welding rod (1.6-2.5mm, e.g., E6013, E6014, E7013, E7018) into the electrode holder.

6.3 Lift TIG Welding Setup (TIG Torch sold separately)

1. Connect the ground clamp cable to the Positive Output Terminal (3) of the welder.
2. Connect the TIG torch cable to the Negative Output Terminal (4) of the welder.
3. Securely attach the ground clamp to the workpiece or welding table, ensuring good electrical contact.
4. Ensure your TIG torch is equipped with the correct tungsten electrode (1.6-2.4mm).
5. If using a gas-shielded TIG torch, connect the gas hose from the torch to your inert gas cylinder (e.g., Argon) and ensure the gas flow is set correctly.

7. Operating Instructions

7.1 Selecting Welding Mode and Adjusting Parameters

1. After powering on the machine, rotate the Parameter Button/Mode Adjustment (2) to adjust the welding current (Amperage) displayed on the LED Digital Display (1).
2. Press down on the Parameter Button/Mode Adjustment (2) to cycle through and select the desired welding mode (MMA/ARC or Lift TIG) and other functions like Hot Start, Arc Force, VRD (Voltage Reduction Device), and Anti-stick.
3. Adjust the current according to the material thickness and electrode size. Refer to the specifications section for general guidelines.

7.2 MMA/ARC Welding Operation

• Ensure the machine is set to MMA/ARC mode.
• Strike the electrode against the workpiece to initiate the arc. The Hot Start feature assists in easier arc ignition.
• Maintain a consistent arc length and travel speed for a smooth weld bead. The Arc Force feature helps prevent the electrode from sticking.
• After welding, chip off the slag with the wire brush provided.

7.3 Lift TIG Welding Operation

• Ensure the machine is set to Lift TIG mode.
• Gently touch the tungsten electrode to the workpiece and then lift it slightly to initiate the arc.
• Maintain a small gap between the tungsten and the workpiece, and feed the filler rod into the weld puddle as needed.
• Ensure proper gas shielding throughout the welding process.

8. Maintenance

Regular maintenance ensures the longevity and optimal performance of your welding machine.

• **Cleaning:** Periodically clean the machine's exterior with a dry cloth. Use compressed air to blow out dust from the cooling vents. Ensure the machine is unplugged before cleaning.
• **Cable Inspection:** Regularly inspect all cables (power, electrode holder, ground clamp, TIG torch if applicable) for cuts, fraying, or damaged insulation. Replace damaged cables immediately.
• **Terminal Connections:** Check that all terminal connections are tight and free from corrosion.
• **Cooling Fan:** Ensure the cooling fan is free from obstructions and operating correctly.
• **Storage:** Store the welder in a dry, clean environment away from direct sunlight and extreme temperatures.

9. Troubleshooting

10. User Tips

• **Initial Setup:** The welder is generally ready for MMA welding straight out of the box, requiring only the connection of the provided electrode holder and ground clamp. For Lift TIG, a separate TIG torch and gas supply are needed.
• **Electrode Selection:** For general purpose welding, E6013 electrodes are often recommended for beginners due to their ease of use and smooth arc.
• **Practice:** If you are new to welding, practice on scrap metal to get a feel for the machine and develop your technique before working on important projects.
• **Portability:** Take advantage of the machine's lightweight design and shoulder strap for easy transport to different work locations.

11. Warranty and Support

The HITBOX ARC200S Mini Welder comes with a 2-year warranty. For any technical support, warranty claims, or inquiries, please contact the seller or manufacturer directly. Ensure you retain your proof of purchase for warranty purposes.
