Guidelines for hand torch cutting

Drag the torch tip lightly and smoothly across the workpiece to keep a stable cut.

Sometimes the torch sticks slightly to the workpiece when you cut with
FineCut cartridges. This is not an indication of a problem.

Pulling, or dragging, the torch across the cut is easier than pushing it.

If sparks spray up from the workpiece, move the torch more slowly, or set the output current
higher.

While cutting, make sure that sparks are coming from the bottom of the workpiece. When
cutting correctly, the sparks lag slightly behind the torch as you cut (15° – 30° angle from
vertical).

Hold the torch tip perpendicular to the workpiece
so that the head of the torch is at a 90° angle to
the cutting surface. Observe the cutting arc as
the torch cuts.

If you fire the torch unnecessarily, you shorten the
life of the cartridge.

For straight-line cuts, use a straight edge as a
guide. To cut circles, use a template or a radius
cutter attachment (a circle cutting guide). For
beveled cuts, use a bevel cutting guide. Refer to
the
Powermax65/85/105 SYNC Parts Guide
(810490).

To troubleshoot problems with cut quality, refer
to
Common problems on page 123.
Guidelines for HyAccess specialty cartridges
Compared to standard cutting
cartridges, HyAccess cartridges increase
the range of the hand torch by
approximately 7.5 cm (3 inches).
HyAccess cartridges also increase the
visibility of the workpiece.
