4. Arahan Operasi

The 220818 Shield is designed for drag cutting applications. Proper operating techniques are crucial for achieving clean cuts and maximizing consumable life.

• Drag Cutting: For drag cutting, the shield is designed to make direct contact with the workpiece. Maintain a consistent, light drag on the material surface.
• Torch Angle: Hold the torch perpendicular to the workpiece for most cuts. A slight angle may be used for beveling or specific applications.
• Kelajuan Perjalanan: Adjust travel speed according to material thickness and desired cut quality. Too slow can lead to excessive dross; too fast can result in incomplete cuts.
• Amperage Setting: Ensure your plasma system's amperage is set within the recommended range of 45-85 A for this shield. Refer to your plasma cutter's manual for specific settings based on material type and thickness.
• Menindik: When piercing thicker materials, use the recommended piercing technique from your plasma system's manual to avoid damage to the shield and other consumables.

5. Penyelenggaraan dan Penjagaan

Regular inspection and proper maintenance of the shield and other consumables are vital for consistent performance and extended lifespan.

• Pemeriksaan Harian: Before each use, inspect the shield for signs of wear, such as excessive pitting, gouging, or deformation of the orifice.
• Pembersihan: If the shield accumulates spatter, gently clean it with a non-abrasive tool. Avoid using harsh chemicals or abrasive materials that could damage the shield's surface.
• Penggantian: Replace the shield when its performance degrades, or visible damage is present. A worn shield can lead to poor cut quality, increased dross, and potential damage to other torch components.
• Storan: Store new shields in a clean, dry environment to prevent contamination or damage.

6. Penyelesaian masalah

If you encounter issues during operation, consider the following common troubleshooting steps related to the shield:

• Poor Cut Quality / Excessive Dross:
  • Inspect the shield for wear or damage. Replace if necessary.
  • Check other consumables (nozzle, electrode) for wear.
  • Verify correct travel speed and amptetapan erage.
• Torch Not Firing / Intermittent Arc:
  • Ensure the shield is properly seated and the retaining cap is hand-tight.
  • Check for any foreign material obstructing the shield's orifice.
  • Inspect the electrode and nozzle for damage or contamination.
• Jangka Hayat Boleh Digunakan Pendek:
  • Confirm correct amperage and air pressure settings for the material being cut.
  • Avoid excessive piercing or cutting too slowly.
  • Ensure proper torch height and drag technique.
