CUTMASTER 40
9.
Follow normal recommended cutting
practices as provided in the power
supply operator's manual.
NOTE!
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.
Piercing With Hand Torch
1.
Hold the torch away from your body.
2.
The torch can be comfortably held in
one hand or steadied with two hands.
Position the hand to press the Trigger on
the torch handle. With the hand torch,
the hand may be positioned close to
the torch head for maximum control or
near the back end for maximum heat
protection. Choose the technique that
feels most comfortable and allows good
control and movement.
NOTE!
The tip should never come in contact with the
workpiece except during drag cutting operations.
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.
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
