Double-layer nozzle

0.06 MPa

• Cutting with oxygen or nitrogen
• Cutting with an extension tube to focus the high-energy laser on the material, avoiding incomplete cuts or dross

• Gas pressure control: Precise gas pressure control is required when cutting with oxygen. We recommend using a proportional valve & pressure reducer to regulate gas pressure.
• • Insufficient pressure: slag residue or dross
  • Excessive pressure: lower laser beam stability
• Calibration requirements: When replacing a single-layer nozzle with a double-layer nozzle, perform red light calibration to ensure processing quality.

Ordinary nozzle

> 1.2 MPa

• Non-contact cutting, preventing material surface scratch

Higher gas pressure for thicker material: Ordinary nozzle requires higher gas pressure (typically 1 MPa / 1.2 MPa) to cut through steel plates thicker than 2 mm

SaveGas™ nozzle

> 0.6 MPa

• Saving gas
• Cutting thick materials

• Avoid thin material processing: Not recommended for thin material (thichness < 2 mm) cutting, which may cause material deformation.
• Test cut: Before processing, test cut a sample like a 20 × 20 mm square to ensure optimal cutting results
• Ceramic ring related
• • Before processing: Ensure that the ceramic ring is clean and that it can retract and extend normally
  • After processing: Check if the ceramic ring is damaged or attached with debris. To replace it, refer to this guide.

CNC cleaning nozzle

0.5–⁠ 0.6 MPa

• Cleaning large and flat surface, such as steel plates and molds
• Uniform cleaning, not uneven cleaning

• Do not use the handheld cleaning nozzle as shown to clean rust with xTool MetalFab CNC Cutter.

CNC cleaning nozzle

1. Detach the welding tip from the welding gun.

2. Turn the original nozzle counterclockwise to remove it.

3. Screw in the target nozzle clockwise. Ensure that it is well secured.

4. Install the assembled cutting tip back to the welding head.

1. Detach the welding tip from the welding gun.

2. Remove the welding tip from the graduated tube.

3. Insert the cleaning nozzle to the graduated tube.

4. Replace the cutting tip with the assembled cleaning nozzle and graduated tube.

1. Take out the SaveGas™ nozzle from the welding head by turning it clockwise.

2. Take out the nozzle nut by turning it counterclockwise.

3. Take out the damaged or soiled ceramic ring.

3. Put the new ceramic ring in place.

4. Reinstall the nozzle nut.

5. Tighten the nut clockwise.

4. Follow instructions on How to Calibrate the Camera of xTool MetalFab CNC Cutter to operate with xTool software.

1. Peel off the protective film.

2. Place the board onto the slats inside xTool MetalFab CNC Cutter.

3. Take off the cutting tip.

1. Install the short fixing bars.

2. Open the protective lid.

3. Place the level in the device.

4. Observe the level bubble.
5. 1. If the bubble is centered, the device is even. You may continue the rest installation and operation.
   2. If the bubble is not centered, slightly adjust the leveling feet of the device.

1. Place a slat with its teeth facing up and its ends fitting snugly into two slots in the working area.

2. Place slats with one slot apart. Decide the number of slats to be placed as required.

3. Place a material on the slats.
