2. Safety Information
WARNING: Welding can be hazardous. Read and understand all safety precautions before operating this machine.
- Electric Shock: Can kill. Do not touch live electrical parts. Wear dry welding gloves and protective clothing. Ensure proper grounding.
- Fumes and Gases: Can be hazardous to your health. Keep your head out of the fumes. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone.
- Arc Rays: Can injure eyes and burn skin. Wear a welding helmet with a proper shade of filter plate to protect your face and eyes when welding or watching. Wear appropriate eye protection with side shields when not welding.
- Fire and Explosion: Welding can cause fire or explosion. Keep flammable materials away from the welding area. Have a fire extinguisher nearby.

5. Operating Instructions
5.1 General Operation
The TIG 205 Pro features a large LED display for easy readability and intuitive controls. The main rotary knob adjusts the amperage, while the "MODE" button cycles through different welding processes. The "Fn" (Function) button allows access to advanced settings, and "REMOTE" activates remote control options, such as a foot pedal.
Figure 5.1: Close-up of the large LED display and control panel.
5.2 Welding Mode Selection
Press the MODE button to cycle through the available welding processes:
- COLD TIG: Ideal for thin materials, offering precise control and minimal heat input.
- 4T DC TIG: Four-stroke TIG welding for longer welds, allowing continuous current without holding the trigger.
- COLD SPOT TIG: For precise spot welding with controlled heat.
- 2T DC TIG: Two-stroke TIG welding, current is active while the trigger is held.
- STICK (MMA): For traditional stick electrode welding.

5.3 Amperage Adjustment
Rotate the large red knob on the right side of the display to adjust the welding amperage. The current value will be displayed prominently on the LED screen.
5.4 Foot Pedal Control (Optional)
The TIG 205 Pro is compatible with an ARCCAPTAIN 5-pin TIG foot pedal (not included). Connecting a foot pedal allows for remote control of the welding current, providing greater precision and comfort during TIG welding, especially for intricate work.
6. Welding Modes Details
6.1 TIG Welding (DC TIG, 2T/4T, Cold TIG, Cold Spot TIG)
The TIG 205 Pro offers advanced DC TIG welding capabilities with a 99.99% arc initiation success rate and 400% increased arc start response speed due to its exclusive internal MCU control. This precision is crucial for sheet metal and bodywork.
- 2T (Two-Stroke) Mode: Press and hold the torch trigger to start the arc. Release to stop.
- 4T (Four-Stroke) Mode: Press and release the trigger to start the arc. Press and release again to stop. This mode is ideal for long welds as it reduces finger fatigue.
- COLD TIG: This mode is designed for welding very thin materials by minimizing heat input, preventing warping and discoloration.
- COLD SPOT TIG: Provides controlled spot welds, useful for tacking or joining thin sheets with minimal distortion.
