CUTMASTER A80, A120
OPERATION 4T-8 Manual 0-5119
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 operator’s 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
WARNINGS
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
before disassembling the torch, leads, or
power supply.
CAUTION
Sparks from plasma gouging can cause damage
to coated, painted or other surfaces such as glass,
plastic, and metal.
Check torch parts. The torch parts must
correspond 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
information as related to the Power Supply
used.
Optimum torch travel speed is dependent on cur-
rent 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.
