11. CUTTING DATA
In this chapter are cutting data charts. These data are approximate and should only be used as
a guide. Many factors have influence on the cutting result, such as plate size, hose assembly
length, material temperature, ambient temperature and so on. It is the responsibility of the
operator to gain such knowledge about the plasma cutting process that he can make such
adjustments to achieve the best possible result and economy.
In the charts the distance is given in mm and the voltage in V. The voltage can depend on
many different factors. Therefore the actual distance in mm has priority over the voltage.
When changing process gas the built in gas purging cycle may not be long enough to fully
flush all remaining gas from the system. It is advised to flush the system for 10-15 s extra by
means of the gas test switches.
To keep high and even quality and to maintain consumable life time it is important to properly
take care of the torch.
Oil and grease on the consumables when cutting with oxygen dramatically shortens the life
time and can even lead to destruction of the torch. Therefore torch heads and consumables
must be properly stored and handled so that they are not subjected to dirt, oil etc.
O-rings on the torch head must be changed as soon as they show signs of wear or damage.
They should be lubricated according to the recommendations in this manual. It is however
forbidden to lubricate the o-rings on the consumables.
Consumables should be changed when the cutting quality is no longer acceptable.
