Setup
Air Compressor Filter Connection
Proper connection of the air compressor filter is crucial for optimal performance and longevity of your plasma cutter. The CUT-55DS features a built-in air pressure regulator for convenience.
Video 1: Demonstrates the connection of the air compressor filter to the plasma cutter, ensuring proper air flow and filtration.
Ensure the air filter is securely attached to the machine's air intake. If the provided joint is not suitable, use a wrench to unscrew the original joint and replace it with the appropriate 1/4" NPT air connector. Tighten all connections with a wrench and seal with sealing tape for an airtight connection. Finally, connect your air hose using a quick connector.

After connecting the air filter, attach the earth lead to your workpiece and the AG60 torch to the machine. Adjust the air pressure using the regulator to the recommended PSI (typically 50-65 PSI for 55A cutting). The digital display will show real-time parameters. Perform test cuts on scrap material to familiarize yourself with the machine's operation.
Operating Instructions
Cutting Capacity and Torch Operation
The CUT-55DS offers powerful cutting capacity with an ideal clean cut of 3/10'' at 110V and 1/2'' at 220V. The maximum cut thickness is 3/5'' at 110V and 4/5'' at 220V. The non-touch pilot arc AG60 torch allows for efficient cutting through rough, painted, and rusty surfaces, extending consumable life.
