7.5 CUTTING
1. Press the torch trigger. The pilot arc will ignite. Then you have to
immediately attach the torch to the cut material. At this point begins to burn
the main arc between the torch and the material.
2. Move the torch with a constant speed. Cutting speeds vary according to
torch output amperage, the type of material being cut, and operator skill.
3. Output current setting or cutting speeds may be reduced to allow slower
cutting when following a line, or using a template or cutting guide while still
producing cuts of excellent quality
4. To achieve a good cutting quality make sure the distance between the tip
and the material is about 3,5 mm. The Spacer Spring
5391
located at the
end of the plasma torch guarantees the distance (or Spacer for contact
cutting
5396
). At a greater distance decreases cutting power and the arc
may go off. With too small distance the torch parts will be worn off faster.
5. Plasma cutting may be done in all possible positions (vertically, horizontally,
overhead, vertical ascending and descending), but as far as possible
choose primarily horizontal cut. In other positions the operator is
increasingly threatened by flying drops of molten material.
