10 The cutting technique and condition
WARNING
Plasma arc exposure against a body part such as hand or finger may cause a burn.
·When the cutting torch switch is pressed, air can blow from cutting tip end and
high voltage can be generated from the cutting tip, so please never touch it!
Regarding cutting method of the Product, according to the relative position of cutting tip and cutting
material, cutting methods can be classified into contact cutting and non-contact cutting.
10.1 The contact cutting
Please avoid unnecessary operation of the cutting torch switch, otherwise the consumption of the
※
electrode can be accelerated by generating arc without base metal.
Cutting
starts
·
cutting tip end gently touches
the base metal end.
·
When cutting tip end centre
and the surface of the base metal
end are on same level position,
turn on the cutting torch switch
Do not press switch under the
statues when cutting tip side
and base metal end touches or
cutting tip vertical contacts with
the base metal, otherwise it
can causes cutting tip burning
loss.
During
cutting
·
Hold the cutting torch as
vertical as possible and cut with
certain speed.
·
The suitable inclining angle of
the cutting torch against the base
metal is within
±
5
°
.
Reference
Please
remove
the
spatter
attached with the cutting tip end
by using fine hole file in advance
to make the
cutting torch
operation more smooth.
Excessively fast cutting speed
may bring too much spatter. It
not only can cause the fail of
cutting, but also the cutting
torch
body
burning
loss,
causing human injury by the
carbonization.
Cutting
finishes
·
When reaching the end of
base metal, lift up the cutting
torch and cut off the cutting torch
switch.
Please finish the cutting on the
status when cutting tip contacts
with the base metal. Because
the strong arc is generated at
cutting tip side, cutting tip
burning loss can happen.
