Ensure spatters fly from the bottom of work piece while cutting. If
spatters fly from the top of work piece, it indicates that the work piece
can not be fully cut because the cutting torch is moved too fast or the
cutting current is too low.
Keep the nozzle slightly touching the work piece or keep a short
distance between the nozzle and work piece. If the torch is pressed
against the work piece, the nozzle may stick to the work piece, and
smooth cutting is unavailable.
For cutting round work piece or to meet precise cutting requirement,
molding board or other assistant tools are needed.
It is recommended to pull the cutting torch while cutting.
Keep the nozzle of cutting torch upright over the work piece, and
check if the arc is moving with the cutting line. If the space is not
enough, don't bend the cable too much, step on or press upon the
cable to avoid suffocating of gas flow. The cutting torch may be
burned because the gas flow is too small. Keep the cutting cable away
from edge tools.
Clean up the spatters on the nozzle timely, for it will affect the cooling
effect of the nozzle. Clean up the dust and spatters on the torch head
after using everyday to ensure good cooling effect.
The work piece is not cut fully. This may be caused by:
1.
The cutting current is too low.
2.
The cutting speed is too high.
3.
The electrode and nozzle of the torch are burned.
4.
The work piece is too thick.
Molten slag drops from the bottom of workpiece. This may be caused by:
1.
The cutting speed is too low.
2.
The electrode and nozzle of the torch are burned.
3.
The cutting current is too high.
