2. Safety Information
Always prioritize safety when operating welding equipment. Read and understand all safety warnings and instructions before use. Failure to do so may result in serious injury or death.
General Safety Precautions:
- Wear appropriate personal protective equipment (PPE), including welding helmet, gloves, protective clothing, and safety shoes.
- Ensure adequate ventilation to avoid inhaling welding fumes.
- Keep a fire extinguisher nearby.
- Do not operate the machine in wet conditions or near flammable materials.
- Ensure proper grounding of the welding machine.
- Disconnect power before performing any maintenance or adjustments.
3. Setup and Connections
Follow these steps to properly set up your HITBOX HBT250P welding machine:
- Power Connection: Ensure the power switch is in the OFF position. Connect the power cable to a suitable AC 220V power outlet.
- Ground Clamp Connection: For MMA/ARC welding, connect the ground clamp cable to the negative (-) terminal on the front panel. For TIG welding, connect the ground clamp cable to the positive (+) terminal. Securely attach the ground clamp to the workpiece or welding table.
- Electrode Holder Connection (for MMA/ARC): Connect the electrode holder cable to the positive (+) terminal on the front panel.
- TIG Torch Connection (for TIG): Connect the TIG torch cable to the negative (-) terminal on the front panel. Ensure the gas hose from the TIG torch is also connected to the gas inlet on the machine.
- Input Gas Connection (for TIG): Connect your argon gas supply hose to the "GAS" inlet located on the rear panel of the machine. Ensure all connections are tight to prevent gas leaks.
- Power On: Flip the power switch on the rear panel to the ON position. The digital display on the front panel should illuminate.

4. Operating Instructions
The HBT250P offers multiple welding modes. Select the appropriate mode and adjust parameters using the control panel.
4.1 MMA/ARC Welding
- Ensure the electrode holder is connected to the positive (+) terminal and the ground clamp to the negative (-) terminal.
- Select "MMA" mode on the control panel (refer to Figure 3).
- Adjust the welding current (Amps) using the adjustment knob.
- Insert the appropriate electrode into the electrode holder.
- Strike an arc on the workpiece to begin welding.
- After welding, use a chipping hammer and wire brush to remove slag and clean the weld.

4.2 TIG Welding (AC/DC, Pulsed)
For TIG welding, ensure the TIG torch is connected to the negative (-) terminal, the ground clamp to the positive (+) terminal, and the argon gas supply is connected and open.
- Select "TIG" mode on the control panel.
- Choose between AC TIG (for aluminum) or DC TIG (for stainless steel, carbon steel, copper, etc.).
- Optionally, select "Pulsed TIG" for enhanced control and reduced heat input.
- Adjust welding parameters such as Start Amps, Peak Amps, Base Amps, Pulse Frequency, AC Balance, Down Slope, and Finish Amps using the mechanical gear knob and corresponding buttons (refer to Figure 3 and Figure 6).
- Ensure the correct tungsten electrode and gas nozzle are installed on the TIG torch.
- Initiate the arc using the HF TIG function and begin welding.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your welding machine.
- Cleaning: Regularly clean the machine's exterior and ventilation openings to prevent dust and debris buildup. Use a dry, soft cloth. For internal cleaning, compressed air can be used, but ensure the machine is unplugged and allow sufficient time for any moisture to dissipate before powering on.
- Cooling System: The machine is equipped with high-speed cooling fans. Ensure these fans are not obstructed and are functioning correctly to prevent overheating.
- Cable and Connections: Inspect all cables, connections, and the TIG torch/electrode holder for wear, damage, or loose connections before each use. Replace any damaged components immediately.
- Consumables: Regularly check and replace TIG torch consumables (tungsten electrodes, collets, collet bodies, gas nozzles) as they wear out to maintain weld quality.
6. Troubleshooting
The HBT250P is designed with built-in protections. If you encounter issues, consider the following:
- No Power: Check the power cable connection, the power switch, and the circuit breaker.
- Overvoltage/Overcurrent/Overload/Overheating: The machine has protective features. If a protection indicator lights up or the machine shuts down, allow it to cool down. Check for proper ventilation and ensure you are not exceeding the machine's duty cycle.
- Poor Weld Quality: Verify correct parameter settings for the material and welding process. Check consumables for wear, ensure proper gas flow (for TIG), and clean the workpiece thoroughly.
- Arc Instability: Check for loose connections, proper grounding, and correct electrode type/size.
If problems persist, please contact customer support for assistance.
