How to Keep Plasma Cutting Systems Clean

Maintenance Best Practices for Hand-held Plasma Cutting Systems

When it comes to proper plasma cutting, taking care of your equipment is key. Routine checks ensure the machine functions as intended, giving you the best performance. To help you in the process, here are some tips for maintaining your plasma cutting system each day, each week and on an ongoing basis.

Daily Operation Checks

• Don’t assume the last operator left everything in proper order. Check the primary power and set the voltage selector controls, jumpers, and similar components to match the primary power voltage and phase before turning on the power.

• Purge the compressed air or gas line to remove moisture.

• Check the torch tip and replace as required.

• Replace the electrode when worn more than 1/16th.

Weekly Maintenance

• Test the springs and replace the start cartridge if a spring seems weak.

• Inspect the torch for cracks or exposed wires, and check the shield cup for spatter.

• Check the cooling fan for proper operation and unobstructed airflow; vacuum or blow out the fan as needed.

• Check cables and hoses for cracks and leaks.

• Check for any air pressure issues.

3-Month Maintenance

• Replace all broken parts and clean the exterior of the power supply.

6-Month Maintenance

• Check the internal air filter and clean or replace as required.

• Use a strong clamp and check the cable-to-clamp connection. Clamp to clean, bare metal and clamp as near to the work piece as possible.

• Remove the machine covers, vacuum out debris and use shop air to blow out dust. Pay attention to the spaces between cooling fins, which can trap debris.

• Check all contactors and electrical connections for signs of severe arcing or pits, replacing components as necessary. Clean and blow off with shop air as needed.
