2. Safety Information

WARNING: Welding can be dangerous. Always follow safety precautions to prevent injury or death.

• Electric Shock: Can kill. Ensure proper grounding. Do not touch live electrical parts. Wear dry welding gloves.
• Fumes and Gases: Can be hazardous to your health. Keep your head out of the fumes. Use ventilation or exhaust to remove fumes and gases from the breathing zone.
• Arc Rays: Can burn eyes and skin. Wear a welding helmet with a proper shade filter and protective clothing to protect your eyes and skin.
• Fire and Explosion: Welding sparks can cause fire or explosion. Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
• Hot Parts: Can cause severe burns. Allow welded materials to cool before handling.
• Read and understand the entire manual before installation or operation.

4.2 Power Connection

The HITBOX TIG200A supports dual voltage input (110V/220V). Ensure the power source matches the machine's requirements and that the appropriate power cord and plug are used. A convert plug is included for convenience.

• Connect the power cord to a suitable grounded electrical outlet.
• Verify the input voltage switch (if present) is set correctly for your power supply.

4.3 TIG Welding Setup

1. Connect the TIG torch to the 'Cutting Torch' output terminal.
2. Connect the ground clamp to the 'Ground Clamp' terminal and securely attach it to the workpiece.
3. Connect the shielding gas (Argon) cylinder to the gas inlet on the machine via a regulator and hose.
4. Install the appropriate tungsten electrode and gas lens/collet into the TIG torch.
5. Set the TIG/Stick Exchange switch to 'TIG'.

4.4 Stick (MMA) Welding Setup

1. Connect the electrode holder to the 'Electrode Holder' output terminal.
2. Connect the ground clamp to the 'Ground Clamp' terminal and securely attach it to the workpiece.
3. Insert the appropriate welding electrode into the electrode holder.
4. Set the TIG/Stick Exchange switch to 'MMA'.

5. Operating Instructions

5.1 General Operation

1. Ensure all connections are secure and correct for the chosen welding process.
2. Turn on the main power switch located on the rear of the machine.
3. Select the desired welding mode (TIG or MMA) using the TIG/Stick Exchange switch.
4. Adjust the welding current using the Adjustment Current knob. The digital display will show the set amperage.
5. For TIG welding, open the gas cylinder valve and set the gas flow rate using the air regulator.
6. Wear all necessary personal protective equipment (PPE) including a welding helmet, gloves, and protective clothing.

5.2 TIG Welding Process

The HITBOX TIG200A features high-frequency arc ignition for TIG welding.

1. Position the TIG torch over the workpiece with the tungsten electrode close to the joint.
2. Press the torch trigger to initiate the arc. The high-frequency start will create an arc without touching the tungsten to the workpiece.
3. Maintain a consistent arc length and travel speed. Add filler rod manually if required.
4. Release the torch trigger to stop welding. Allow post-flow gas to shield the weld puddle as it cools.

5.3 Stick (MMA) Welding Process

1. Strike the electrode against the workpiece to initiate the arc.
2. Maintain a consistent arc length and travel speed, moving the electrode along the joint.
3. Continue welding until the electrode is consumed or the weld is complete.
4. Chip off any slag after the weld has cooled.

6. Maintenance

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

• Cleaning: Periodically clean the internal components of the machine using dry compressed air to remove dust and debris. Ensure the machine is unplugged before cleaning.
• Cable Inspection: Regularly inspect all welding cables, torch, and ground clamp for damage, cuts, or loose connections. Replace damaged components immediately.
• Fan Vents: Keep the cooling fan vents clear of obstructions to ensure proper airflow and prevent overheating.
• Tungsten Electrodes: For TIG welding, ensure tungsten electrodes are properly sharpened and free from contamination.
