Frequently Asked Questions (FAQ)
A1: The main function of a shield cap is to protect the nozzle and electrode from metal spatter, slag, and debris. It also helps optimize gas flow to stabilize the plasma arc and improve cutting quality.
A2: Shield caps are usually made of copper or copper alloy. The surface may be coated with a special coating to enhance wear resistance and high temperature resistance.
A3: The replacement frequency depends on your usage frequency and cutting conditions. You should inspect the shield cap regularly and replace it when there is serious surface wear, ablation, cracking, or damage.
A4: A short lifespan is often caused by improper cutting parameters (such as excessively high current or incorrect gas pressure) or excessive slag generated by the specific cutting materials.
A5: Plugging is typically caused by too much slag or gas produced during the cutting process. To fix this, thoroughly clean the shield cap and ensure you are using a pure gas supply.
A6: Always turn off the cutting machine's power before replacing the shield cap. Clean the shield cap seat to prevent dust or debris from interfering, and install it properly according to the manual to prevent damage to the components.
