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.
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 in-
stalled, 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 dam-
age 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 sys-
tem 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 precau-
tions 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 sys-
tem before disassembling the torch,
leads, or power supply.
!
CAUTION
Sparks from the cutting process can
cause damage to coated, painted, and
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 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.
