THE PROCUT45 PLASMA CUTTING GUIDE
The PROCUT45 Plasma Cutting Guide
(SKU 8612590) has two wheels that allow
you to easily cut in straight lines, curves
and circles.
CUT QUALITY
A clean cut depends on
several factors. The best
quality cut will be produced
when all these variables are set
correctly for the material
thickness and type of material
being cut.
The standard rule of thumb is thicker materials require more
amperage.
Set the machine to full output and vary your travel speed with
thick material. Thin material requires lower amperage and a
lower-amperage tip to maintain a narrow kerf. The kerf is the
width of the cut material that is removed during cutting.
Amperage and speed are critical to producing a good quality
cut. Moving faster across the metal (especially on aluminum)
will result in a cleaner cut (Fig. 12).
Visually follow the arc coming out from the bottom of the cut
to determine if you're going too fast or too slow.
• The arc exits the material at a slight angle, away from the
direction of travel, when the speed is correct.
• An arc exiting straight down means you're going too slow.
You will have an unnecessary buildup of dross or slag.
• An arc that sprays across the material’s surface without
cutting all the way through means you’re going too fast.
