3.4. CUTTING OPERATION. RECOMMENDATIONS.
Adjust the welding current (potentiometer 1) according to the
cutting mode, the accessories installed and the material and
thickness to be cut. Verify that the vacuum pneumatic
pressure is between 5.5 -6 bar
Press torch switch and form pilot arc. If cutting is not started
for 5 s, the arc will turn off. The arc ignition system is
automatic by contact node ("Back stricking system"), this
system requires the equipment to be connected to the
pneumatic network (there must be air pressure)
Start the cut from the edge of the piece. To cut, you can rest
the torch on the workpiece, but do not apply pressure. The
cutting speed depends on the thickness of the piece
If the piece is less than 5 mm thick, you can start cutting from
the inside of the piece as indicated in the figure.
During cutting, keep the torch as indicated in the figure. The
arc must be perpendicular to the piece. If the arc leans or
fails to cut, the torch speed may be high.
The machine allows to cut pieces with gaps or holes without
the need to restart the arc (Grid cutting)
