SPARCIN 9 / SPARCIN 9C

Convex kerf
• Too much distance between nozzle and work piece, or too high cutting current. By
first lowering the torch and then if necessary lowering the current the kerf can be
straightened.
Some combinations of plasma generating gas and material can more than others cause
convex kerfs.
Optimising consumable lifetime
The consumable parts of the water cooled torch guarantee the best possible consumable
lifetime and optimum cutting economy. To optimise the consumable lifetime the following
instructions must be followed.
Optimising electrode lifetime
• When piercing the torch must not be too close to the work piece
• Program the sequence so that the plasma arc goes out before the torch goes over the
edge of the work piece. If the pilot arc re-ignites the electrode lifetime is reduced.
• The electrode lifetime can be increased by programming the sequence so that several
parts are cut in one sequence, thereby reducing the number of starts.
• When changing plasma generating gas the gas system must be flushed.
Optimising nozzle lifetime
• When piercing, the torch must not be too close to the work piece. The piercing
distance should be at least double the cutting distance.
• The distance between nozzle and work piece must be kept constant so that the nozzle
does not touch the work piece.
