3. Operating instructions
Check that the machine has been properly connected to power supply.
Check that the torch is fitted with appropriate consumables for the job at hand.
Connect the earth lead clamp directly at the work piece, ensuring that a good contact is
obtained. If necessary, clean the surface from paint, rust, dirt, etc.
Cutting
• Switch the machine’s main power switch ON.
The READY lamp will light and the fan will start working.
• Choose process power, 5-25 A. Check that the consumables in the torch match
the current setting.
• Manoeuvre the torch in position for cutting.
• Press the START-switch on the torch handle.
The pilot arc will burn for a few seconds. If contact with the work piece is not
obtanined within this time, the pilot arc goes out. Then make a new try.
• To end the process, release the START-switch. The plasma arc goes out
instantaneously. Air will continue to flow for about 30 seconds.
NOTE! When the machine is not in use or is only working at long intervals, switch off the
machine. It contains mechanical components that should not be exposed to unnecessary wear.
It also protects against unvoluntarily firing the pilot arc.
