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 Powermax45/65/85/105 SYNC Parts Guide
(810490).

To troubleshoot problems with cut quality, refer
to Common problems and solutions on
page 89.
Mark with the hand torch
You can mark mild steel, stainless steel, and aluminum by using a FineCut cartridge with bottled air
or shop-compressed air.
Marking process guidelines
Before you begin marking:
 Install a FineCut cartridge.
 Marking is only possible with a FineCut cartridge.
 Set the plasma power supply output current to 9 A through 19 A.
 A current setting of 9 A will give you the lightest mark. A current setting of 19 A will give
the heaviest mark.
