CUTMASTER 60i
3.
Angle the torch slightly to direct blow-
back particles away from the torch tip
(and operator) rather than directly back
into it until the pierce is complete.
4.
In a portion of the unwanted metal start
the pierce off the cutting line and then
continue the cut onto the line. Hold the
torch perpendicular to the workpiece
after the pierce is complete.
5.
Slide the trigger release toward the back
of the torch handle while simultaneous-
ly squeezing the trigger. The pilot arc
will start.
Trigger Release
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 characteristic
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 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 fluctuations
•
Torch standoff height
•
Proper work cable connection

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 op-
erator'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.07, Torch Parts Selection.
Gouging performance depends on parame-
ters 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.
NOTE!
Refer to Appendix Pages for additional informa-
tion 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 settings depend on torch travel
speed, mode of operation (hand or machine
torch), and the amount of material to be
removed.
