4. Setup
Proper setup is crucial for safe and efficient operation.
4.1 Power Connection
- The TIG-200P ACDC supports dual voltage input (110V/220V). Ensure the correct power cord and plug are used for your power supply.
- Connect the welder to a dedicated circuit with appropriate overcurrent protection.
4.2 Ground Clamp Connection
- Connect the ground clamp cable to the appropriate terminal on the welder.
- Attach the ground clamp securely to the workpiece or a sturdy metal workbench that is electrically connected to the workpiece.
4.3 TIG Torch Connection
- Connect the TIG torch cable to the designated TIG torch connector on the front panel.
- Ensure the connection is tight and secure.
4.4 Gas Regulator and Cylinder Connection
Connect the gas regulator to your Argon or Argon/CO2 gas cylinder. The regulator comes with various connection options for compatibility.
- Ensure the gas cylinder is secured upright.
- Attach the regulator to the cylinder valve, ensuring a tight seal.
- Connect the gas hose from the regulator to the gas inlet on the welder.

5. Operating Instructions
Follow these steps for basic operation of your TIG-200P ACDC welder.
5.1 Power On and Mode Selection
- Turn on the main power switch located on the rear of the machine.
- Use the Welding Mode Button (1 in Figure 4) to cycle through STICK, AC TIG, DC TIG, AC Pulse TIG, DC Pulse TIG, and Spot Welding modes.
- Use the Operation Mode Buttons (2 and 3 in Figure 4) to navigate through sub-modes or parameter groups.
5.2 Parameter Adjustment
The large LED display (6 in Figure 4) will show the current selected parameter. Use the Parameter Adjusting knob (5 in Figure 4) to modify values.
- Current (A): Adjust welding amperage based on material thickness and type.
- Pulse Features: For Pulse TIG modes, adjust pulse frequency (Hz), pulse width, and background current.
- AC Balance: For AC TIG, adjust the AC balance to control cleaning action and penetration.
- Downslope & Post Gas: Adjust downslope time to gradually reduce current at the end of a weld, and post-gas flow time to protect the cooling weld puddle and tungsten.
- Hot Start & Arc Force: For STICK welding, these parameters assist with arc ignition and prevent electrode sticking.
5.3 Aluminum Welding (AC TIG)
The TIG-200P ACDC utilizes a software-controlled square wave for AC TIG, which is ideal for welding aluminum up to 4/25" (approximately 4mm). Adjusting the AC balance and frequency is key to achieving optimal results with aluminum.
5.4 Gas Flow Adjustment
- Slowly open the gas cylinder valve.
- Adjust the regulator knob to set the desired gas flow rate (CFH) as indicated by the ball in the flow tube. Typical TIG welding flow rates range from 10-20 CFH.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your welder.
- Cleaning: Periodically clean the welder's exterior with a dry, soft cloth. Use compressed air to blow out dust from inside the machine, especially from cooling vents. Ensure the machine is unplugged before cleaning.
- Cable Inspection: Regularly inspect all welding cables, power cords, and gas hoses for cuts, cracks, or damage. Replace damaged components immediately.
- Consumables: Check and replace TIG torch consumables (tungsten electrodes, collets, collet bodies, nozzles) as needed. Ensure tungsten is properly ground.
- Connections: Verify that all electrical and gas connections are tight and secure.
7. Troubleshooting
This section addresses common issues you might encounter. For problems not listed here, contact customer support.
7.1 No Power
- Check Power Cord: Ensure the power cord is securely plugged into both the welder and the power outlet.
- Circuit Breaker: Verify that the circuit breaker has not tripped.
- Main Switch: Confirm the welder's main power switch is in the 'ON' position.
7.2 No Arc
- Ground Clamp: Ensure the ground clamp is securely attached to the workpiece and has good electrical contact.
- TIG Torch Connection: Check that the TIG torch is properly connected to the welder.
- Welding Mode: Verify that the correct welding mode is selected for the application.
- Consumables: Inspect the tungsten electrode for proper installation and condition.
7.3 Poor Weld Quality
- Gas Flow: Check the gas flow rate on the regulator. Insufficient or excessive gas flow can lead to porosity.
- Material Cleanliness: Ensure the workpiece is clean and free of contaminants (oil, rust, paint).
- Parameters: Adjust welding current, pulse settings, and AC balance (for aluminum) according to the material and thickness.
- Tungsten Condition: A contaminated or improperly ground tungsten electrode can cause poor arc stability and weld quality.
