Hand torch cutting guidelines
 Drag the torch tip lightly along the workpiece to maintain a steady cut.
 While cutting, make sure that sparks exit from the bottom of the workpiece. The sparks should lag slightly behind the
torch as you cut (15 – 30° angle from vertical).
 If sparks spray up from the workpiece, move the torch more slowly, or set the output current higher.
 With either hand torch, hold the torch nozzle perpendicular to the workpiece so that the nozzle is at a 90° angle to the
cutting surface. Observe the cutting arc as the torch cuts.
 If you fire the torch unnecessarily, you will shorten the life of the nozzle and electrode.
 Pulling or dragging the torch along the cut is easier than pushing it.
 For straight-line cuts, use a straight edge as a guide.
 To keep the torch head steady and slightly above the workpiece while cutting, you can use the skeleton cutting sled
kit (428809) or similar aid.
