b)
Pull the trigger of the cutting torch, and press the
torch switch to start arc. Keep the torch on the edge of
the workpiece for a moment until the workpiece is
completely cut through.
Ensure spatters fly from the bottom of workpiece
while cutting. If spatters fly from the top of workpiece,
it indicates that the workpiece can not be fully cut
because the cutting torch is moved too fast or the
cutting current is too low.
c)
Keep the nozzle of the cutting torch perpendicular to
the workpiece (with an angle of 90° formed by the
nozzle and the cutting surface). Cut along a straight
line, and observe the plasma arc at the same time.
Pull the torch nozzle along the workpiece with a stable
and uniform speed to continue cutting.
d)
Unnecessary start-up of the cutting torch will shorten
the lifespan of the nozzle and electrode.
Pulling the
cutting torch along the cutting direction is easier than
pushing it to the opposite direction.
A ruler can be used as a guide in straight line cutting.
Perforation of the workpiece
The perforating thickness should be half of the normal quality cutting thickness, and the
perforating thickness of this cutting machine can reach up to 25mm.
WARNING
Sparks and hot metal mayhurt your eyes or burn your skin. Sparks and hot
metal will spray from the nozzle when starting the cutting torch in an
inclined position. Do avoid pointing the cutting torch to yourself or others.
a)
Clamp the workpiece with the work clamp, and hold
the cutting torch to form an angle of about 30° with
the workpiece. Keep the distance between the nozzle
and the workpiece within 1.5mm, and start the cutting
torch.
b)
Keep the cutting torch a certain angle with the
workpiece, start the cutting torch, and then slowly
rotatethe cutting torch to the vertical position (90°).
