4. Installation and Setup
This inverter plate is a specialized component. Proper installation is critical for its functionality and the safety of the welding machine. Refer to the specific service manual of your welding machine for detailed instructions.
- Preparation: Ensure the welding machine is powered off and unplugged. Allow any residual charge in capacitors to dissipate.
- Access: Carefully open the welding machine casing to access the existing inverter plate or the designated installation area.
- Removal (if replacing): Document all connections (wiring, connectors, mounting screws) before carefully detaching the old inverter plate. Take photos for reference.
- Installation:
- Align the new TJGOPKUJ TIG-200 250 Inverter Plate with the mounting points.
- Secure the plate using appropriate screws, ensuring it is firmly seated and does not flex.
- Reconnect all wiring and connectors according to your documentation. Double-check each connection for proper polarity and secure fit.
- Inspection: Before closing the casing, perform a thorough visual inspection to ensure no wires are pinched, no components are loose, and all connections are correct.
- Initial Power-Up: Close the casing. Connect the welding machine to the appropriate power supply (AC220V or AC380V). Perform a test power-up according to your welding machine's manual, observing for any unusual behavior.

5. Operation
The TJGOPKUJ TIG-200 250 Inverter Plate functions as a core power conversion unit within a compatible welding machine. Its operation is integrated into the overall functionality of the welder. Once correctly installed, the inverter plate will operate automatically as part of the welding machine's power supply system.
- Power Conversion: The inverter plate converts the incoming AC power (220V or 380V) into a high-frequency AC current, which is then rectified into a stable DC current suitable for welding.
- Control Integration: It works in conjunction with the welding machine's control board to regulate output current and voltage, ensuring precise welding performance.
- Thermal Management: The plate is designed to operate within specific temperature ranges. Ensure the welding machine's cooling system is functioning correctly to prevent overheating.
Refer to your welding machine's primary user manual for specific operational procedures, welding parameters, and safety guidelines related to the complete welding system.
6. Maintenance
Regular maintenance helps ensure the longevity and reliable performance of the inverter plate and the welding machine.
- Cleaning: Periodically, with the power disconnected, open the welding machine casing and gently clean the inverter plate and surrounding areas. Use compressed air to remove dust and debris. Avoid using liquids or abrasive cleaners.
- Visual Inspection: During cleaning, inspect the board for any signs of overheating (discoloration), loose components, cracked solder joints, or damaged traces.
- Connection Checks: Ensure all connectors and wiring remain secure and free from corrosion.
- Environmental Conditions: Operate and store the welding machine in a clean, dry environment, free from excessive dust, moisture, and corrosive fumes.
