- Power Connection: Connect the power cable to a grounded 230V power outlet.
6. Operating Instructions
This section details the operational procedures for the FEIFANKE FKC-750H Plasma Cutter.
6.1 Power On and Initial Settings
- Turn on the power switch (8) on the rear panel.
- Adjust the air pressure using the air reducer valve (10) to the recommended range of 40-70 PSI. Monitor the PSI on the digital screen (1).
- Set the desired cutting current using the current control knob (5). The current will be displayed on the digital screen.
6.2 2T/4T Operating Modes
The machine offers two operating modes for different cutting needs:

- 2T Mode (Semi-Automatic): Ideal for short cuts. Press and hold the torch trigger to start the arc and cut. Release the trigger to stop.
- 4T Mode (Fully Automatic): Suitable for long, continuous cuts. Press and release the torch trigger to start the arc. The arc will remain active until you press and release the trigger again to stop.
Select the desired mode using the operation mode button (6).
6.3 Non-Contact High-Frequency Ignition
The FKC-750H features non-contact high-frequency ignition, allowing for effortless cutting through various surface conditions.

This system ensures an immediate and reliable arc start without physical contact between the torch and the material. This is beneficial for cutting dirty, rusty, or painted surfaces, reducing electrode wear and extending equipment life.
6.4 Post-Flow Function
The post-flow function allows you to set the torch cooling time (post-flow, adjustable from 5 to 20 seconds, with 5-8 seconds recommended). This feature protects the wear parts of the torch and significantly increases their longevity.
7. Cutting Performance
The FKC-750H plasma cutter is designed for powerful and precise cutting of various conductive metals.
