4. Setup
4.1 Power Connection
- Ensure the welder is connected to a 230V power supply.
- Verify that the power outlet and circuit breaker can handle the required amperage.
4.2 Gas Connection (for TIG welding)
- Connect the argon gas tube to the gas inlet on the rear panel of the welder.
- Connect the other end of the gas tube to your argon gas cylinder via a pressure regulator.
- Ensure all connections are secure to prevent gas leaks.
4.3 Welding Cable Connections
The connection polarity depends on the welding mode:
- TIG Mode: Connect the TIG torch to the negative (-) terminal and the ground clamp to the positive (+) terminal.
- MMA Mode: Connect the electrode holder to the positive (+) terminal and the ground clamp to the negative (-) terminal.

5.2 Welding Modes
The HITBOX TIG200PRO offers 6 functions:
- MMA (Manual Metal Arc) Welding: For general-purpose stick welding.
- DC HF TIG Welding: High-frequency start TIG for precise welding of various metals (not aluminum).
- Pulsed TIG Welding: Offers precise digital control over parameters like base current, peak current, frequency, and duty cycle, reducing heat input and distortion.
- TIG Clean: A specialized function for cleaning the weld area (torch not included for this specific function).
- Spot Welding: High-precision spot welding for ultra-thin materials (down to 0.1 mm).
- Cold TIG: A mode for welding with minimal heat input.

5.3 Parameter Adjustment
The digital control allows precise adjustment of various parameters:
- Current: 1-200 A
- Pre-gas: 0-10 seconds (ensures oxidation-free start)
- Post-gas: 1-10 seconds (protects weld pool as it cools)
- Spot Welding Time: 0.01-9 seconds
- Spot Welding Interval: 1-900 ms
- Pulsed TIG Frequency: 0.1-500 Hz
- Pulsed TIG Duty Cycle: 10%-90%
- Base Current (Pulsed TIG): 10-180A
- Peak Current (Pulsed TIG): 10-200A
- Start Ramp (Pulsed TIG): 0-10s
- End Ramp (Pulsed TIG): 0-10s
- End Current (Pulsed TIG): 10-200A

5.4 2T/4T Mode Selection
The welder supports both 2T (Two-Touch) and 4T (Four-Touch) modes for continuous and spot welding applications.
- 2T Mode: Press and hold the torch button to start welding; release to stop. Suitable for short welds.
- 4T Mode: Press and release to start welding; press and release again to stop. Ideal for longer welds, reducing hand fatigue.

7. Troubleshooting
If you encounter issues with your HITBOX TIG200PRO welder, refer to the following common problems and solutions:
- No Power: Check power cable connection, main power switch, and circuit breaker.
- No Arc: Ensure proper grounding, correct electrode/tungsten setup, and sufficient welding current. Check for loose connections.
- Poor Weld Quality: Adjust welding current, gas flow (for TIG), travel speed, and arc length. Ensure workpiece is clean.
- Overheating Protection: If the welder stops and an overheat indicator lights up, allow the machine to cool down. Ensure proper ventilation and do not exceed the duty cycle.
- Gas Flow Issues (TIG): Check argon cylinder pressure, regulator settings, and gas tube connections for leaks or blockages.
