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, or without sufficient power.
Position the torch nozzle at a vertical position and watch
the arc as it cuts along the line.
Shielded Consumables. 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.
• To cut thin material, reduce the amps until you get the best
quality cut.
• For straight-line cuts, use a straight edge as a guide. To cut
circles, use a template or a Hypertherm circle cut guide,
Part No. 027668.
Unshielded Consumables. Maintain an approximate
1/8 inch (3 mm) torch-to-work distance.
