1. Safety Information
Always read and understand all safety warnings and instructions before operating the HITBOX 200A MIG Welder. Failure to follow these instructions may result in electric shock, fire, serious injury, or death.
- Electric Shock: Welding current can cause electric shock. Do not touch live electrical parts. Wear dry, insulating gloves.
- Fumes and Gases: Welding produces fumes and gases. Work in a well-ventilated area. Use local exhaust or ventilation.
- Arc Rays: Arc rays can burn eyes and skin. Wear a welding helmet with appropriate shade and protective clothing.
- Fire and Explosion: Welding can cause fire or explosion. Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
- Hot Parts: Welded parts are hot. Allow them to cool before handling.

3. Setup
3.1 Unpacking and Inspection
Carefully remove the welder and all accessories from the packaging. Inspect for any shipping damage. Report any damage to your supplier immediately.
Verify that all components listed in the packing list are present:
- HITBOX 200A MIG Welder Unit
- MIG Welding Torch
- Ground Clamp
- Electrode Holder (for Stick/MMA welding)
- Gas Hose
- Extra MIG Tips
- Power Cable
3.2 Power Connection
Ensure the power switch on the rear panel is in the "OFF" position before connecting to power. This welder supports dual voltage (110V/220V) and automatically detects the input voltage.
- Connect the power cable to the appropriate power outlet (110V or 220V). Ensure the outlet has sufficient amperage capacity (e.g., 40A breaker for full output).
- Press the power switch on the rear panel to the "ON" position. The LCD display will illuminate.

3.3 Accessory Connection
Proper connection of welding accessories is crucial for safe and effective operation. Refer to the connection diagrams below for different welding modes.
Figure 3.1: Connection modes for MIG (Gas/Gasless), MMA, and Lift TIG welding. Note the polarity changes for different processes.
- MIG Welding (Gasless Flux Core): Connect the ground clamp to the positive (+) terminal and the MIG torch to the negative (-) terminal.
- MIG Welding (Gas Shielded): Connect the ground clamp to the negative (-) terminal and the MIG torch to the positive (+) terminal. Connect the gas hose from your gas cylinder to the gas inlet on the rear panel.
- Stick (MMA) Welding: Connect the electrode holder to the positive (+) terminal and the ground clamp to the negative (-) terminal.
- Lift TIG Welding: Connect the TIG torch to the negative (-) terminal and the ground clamp to the positive (+) terminal. (Note: TIG torch is sold separately).
4. Operating Instructions
4.1 Control Panel Overview
The HITBOX 200A features an intuitive colorful LCD display and control knobs for precise adjustments.
Figure 4.1: The control panel features a digital display for current and voltage, a multi-function/selection button, and adjustment knobs for welding voltage and wire speed.
- Digital Display: Shows current (Amps) and voltage (Volts) settings.
- Multi-function/Selection Button: Press to cycle through welding modes (MIG, MMA, LIFT TIG, Flux Core, Mixed Gas).
- Welding Voltage Knob: Adjusts the welding voltage.
- Wire Speed Knob: Adjusts the wire feed speed (for MIG modes) or current (for MMA/TIG).
4.2 Welding Mode Selection
Use the multi-function/selection button to choose your desired welding process. The selected mode will be highlighted on the colorful LCD screen.
Figure 4.2: The upgraded colorful panel clearly displays the active welding mode and parameters, making selection straightforward.
- MIG (CO2/MIX): For gas-shielded MIG welding with CO2 or mixed gas.
- FLUX: For gasless flux-cored welding.
- MMA: For Stick welding.
- LIFT TIG: For Lift TIG welding (requires separate TIG torch).
4.3 Parameter Adjustment
Adjust welding voltage and wire speed (or current for MMA/TIG) using the respective knobs. The display will show real-time values.
Figure 4.3: Adjusting the welding voltage knob to fine-tune the output for MIG welding. Recommended voltage ranges for MIG gas, gasless, and mixed gas are displayed.
Refer to the welding thickness chart for recommended settings:
Figure 4.4: This chart provides general guidelines for welding thickness across different modes: MIG (1-8mm), LIFT TIG (1-6mm), and MMA (2-12mm).
4.4 Welding Wire Compatibility
The machine is compatible with 0.8mm-1.0mm rolls of solid core wire and flux core wire.
