•
Hold the torch at a 45° angle with the
workpiece. Press the trigger to obtain a pilot
arc. Transfer the arc to the workpiece.
•
Pull the torch back by keeping a 45° angle
with the workpiece and a certain distance
between the torch tip and the molten metal to
avoid consumable life reduction or damage
to the torch.
Changing the torch’s angle change the di-
mensions of the gouge.
•
The gouge profile may vary in accordance with:
1.
speed of the torch over the workpiece
2.
the torch-to-work standoff distance
3.
the angle of the torch to the workpiece
4.
the adjusted current output.
•
To increase width:
- Increase the standoff and/or the current.
- Decrease the speed and/or the angle.
•
To decrease width:
- Increase the speed and/or the angle.
- Decrease the standoff and/or the current
•
To increase depth:
- Decrease the speed and/or standoff.
- Increase the current and/or the angle.
•
To decrease depth:
- Decrease the current and/or the angle.
- Increase the speed and/or standoff.
CUTTING WITH CNC
•
Select the CNC mode with the selection key
(A) in the control panel.
•
Follow indications at paragraph “Connection
of the machine to a CNC”
•
Since the equipment with mechanized torch
can be used with different cutting tables, for the
operations in such configuration it is necessary
to consult the manufacturer’s instructions.
WARNING
Disconnect primary power at the source
and wait that the torch has cooled before
disassembling the torch or torch leads.
Frequently review the Important Safety
Precautions at the front of this Manual. Be
sure the operator is equipped with proper
gloves, clothing, eye and ear protection.
Make sure no part of the operator’s body
comes into contact with the work piece
while the torch is activated.
CAUTION
Sparks from the cutting process can cause
damage to coated, painted, and other sur-
faces such as glass, plastic and metal.
NOTE
Handle torch leads with care and protect
them from damage.
Figure 19
PIERCING WITH A HAND TORCH
Note: Recommended maximum piercing
capacity depends on the torch and on the
cutting current of the cutting unit. Refer to
the torch specification sheet provided with
the cuttig unit. If necessary to make a cut
on a metal sheet with a tickness more than
the maximum piercing capacity without
an edge start, make a hole ø 6mm at least
using an electric drill to start cutting.
•
When piercing with a hand torch, tip the torch
slightly.
Figure 18
•
Complete the pierce off the cutting line and
then continue the cut onto the line. Hold the
torch perpendicular to the workpiece after the
cut is complete. Fig.19
•
Clean spatter and scale from the shield cup
and the tip as soon as possible.
GRATES CUTTING
•
Select the automatic pilot arc mode with the
selection key (A) in the control panel.
GOUGE
•
Select the gouge mode with the selection key
(A) in the control panel.
•
Hold the torch with torch tip within 1.5 mm
from the workpiece.
