Setting up and using the LEITER Vacuum Plate 300 for weld seam testing is straightforward. Here's a step-by-step guide to help you get started:
-
Preparation:
- Before each use, inspect the LEITER Vacuum Plate 300 for any visible damage, such as cracks, splits, or scratches.
- Ensure the filter plate is correctly installed and clean.
- Check the power supply cable, plug, and extension cable for damage.
- Make sure the cooling air openings are clear and unobstructed.
- Verify the sealing lip is in good condition.
- Connect the Vacuum Plate to the appropriate voltage, as indicated on the device.
-
Testing Procedure:
- The welding area must be dry and free of any contaminants before testing.
- Apply a bubble-forming liquid (like soapy water) to the weld seam just before testing.
- Set the pressure setting valve (Vari-Flow Valve) to its minimum pressure setting.
- Position the LEITER Vacuum Plate 300 over the weld seam, ensuring the seam is centered.
- Gently press the Vacuum Plate onto the test area using both handles.
- Turn on the main switch on the Vacuum Plate.
- Adjust the pressure setting valve clockwise to achieve the desired test pressure.
- Monitor the negative pressure reading on the pressure gauge.
- Carefully inspect the weld seam for any leaks, indicated by the formation of bubbles in the test liquid.
- Turn off the main switch, allow the device to cool down, and disconnect the power cord.
- Mark and repair any leaks that are identified during the test.
-
Quick Guide:
- To start, connect the power cord, open the pressure setting valve, place the device on the test area, and apply gentle pressure. Then, switch on the main switch and adjust the pressure as needed.
- To stop, turn off the main switch and disconnect the power cord from the power source.
Following these steps will help you effectively use the LEITER Vacuum Plate 300 for accurate weld seam testing, according to the manufacturer's guidelines.
