Hand Torch Cutting Technique
Firing the torch unnecessarily reduces
nozzle and electrode life.
When cutting, make sure that sparks are exiting
from the bottom of the workpiece.
If sparks are spraying up from the workpiece, you are
moving the torch too fast. The arc below the workpiece
should lag the torch by approximately 15° from vertical.
Hold the torch nozzle at a vertical position and
watch the arc as it cuts along the line.
• Do not push down on the torch when cutting. Lightly drag
the torch across the workpiece to maintain a steady cut.
• Pulling the torch through the cut is easier than pushing it.
• For straight-line cuts, use a straight edge as a guide. To
cut circles, use a template or a radius cutter attachment.
