CUTMASTER A40
OPERATION 4T-8 Manual 0-4978
6. Bring the torch within transfer distance to
the work. The main arc will transfer to the
work, and the pilot arc will shut OFF.
NOTE
The gas preflow and postflow are a character-
istic of the power supply and not a function
of the torch.
When the shield cup is properly installed, there
is a slight gap between the shield cup and the
torch handle. Gas vents through this gap as
part of normal operation. Do not attempt to
force the shield cup to close this gap. Forcing
the shield cup against the torch head or torch
handle can damage components.
7. Clean spatter and scale from the shield cup
and the tip as soon as possible. Spraying
the shield cup in anti - spatter compound
will minimize the amount of scale which
adheres to it.
Cutting speed depends on material, thickness,
and the operators ability to accurately follow the
desired cut line. The following factors may have
an impact on system performance:
Torch parts wear
Air quality
Line voltage uctuations
Torch standoff height
Proper work cable connection
4T.07 Gouging
!
WARNING
Be sure the operator is equipped with proper
gloves, clothing, eye and ear protection and
that all safety precautions at the front of this
manual have been followed. Make sure no
part of the operator’s body comes in contact
with the workpiece when the torch is activated.
Disconnect primary power to the system be-
fore disassembling the torch, leads, or power
supply.
CAUTION
Sparks from plasma gouging can cause dam-
age to coated, painted or other surfaces such
as glass, plastic, and metal.
Check torch parts. The torch parts must cor-
respond with the type of operation. Refer to
Section 4T.09, Torch Parts Selection.
Gouging Parameters
Gouging performance depends on parameters
such as torch travel speed, current level, lead angle
(the angle between the torch and workpiece), and
the distance between the torch tip and workpiece
(standoff).
CAUTION
Touching the torch tip or shield cup to the
work surface will cause excessive parts wear.
Torch Travel Speed
NOTE
Refer to Appendix Pages for additional infor-
mation as related to the Power Supply used.
Optimum torch travel speed is dependent on current
setting, lead angle, and mode of operation (hand or
machine torch).
Current Setting
Current settings depend on torch travel speed,
mode of operation (hand or machine torch), and the
amount of material to be removed.
