• Too high cutting speed. By slowing the cutting speed the angle deviation can be
minimised.
Inconsistent angle deviation
• Worn or damaged consumables. Check the consumables and change if necessary.
• The torch is not fitted straight in relation to the work piece. Check the torch position
and adjust if necessary.
• Magnetic remanence in the work piece. Parts that are handled with electro-magnetic
lift tools may become magnetic. Make sure that the material is handled without using
magnetic lift tools.
Dross formation
Dross free cutting requires that all parameters for each job are optimised.
Dross formation as a result of too low cutting speed
• This type of dross formation occurs when the cutting speed is too low. The dross is
extensive and porous. It is easy to remove. Reduce the dross formation by increasing
cutting speed.
Dross formation as a result of too high cutting speed
• This type of dross formation occurs when the cutting speed is too high. The dross
looks like drops of molten metal and is hard to remove.
By lowering the cutting speed the dross formation can be reduced. If reducing the
speed does not solve the problem it may help to lower the distance between nozzle and
work piece.
Sporadic dross formation
• Worn or damaged consumables. Check and change if necessary.
• This type of dross formation may be material dependant. Some materials cause more
dross than others.
• Work piece temperature. When cutting the first parts from a work piece the dross
formation can be lass than when the material has become heated.
The surface of the kerf
The kerf may be convex or concave. An accurate adjustment of the cutting speed and distance
can help in obtaining a straight cut.
Concave kerf
• Too little distance between nozzle and work piece. Increase the distance in order to
straighten the kerf.
