BUILT TO GET THE JOB DONE
Standard rule of thumb is the thicker the material the more amperage required.
On thick material, set the machine to full output and vary your travel speed. On thinner material, you need to turn down the amperage and
change to 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. The faster you move (especially on aluminium), the cleaner your cut will
be. To determine if you're going too fast or too slow, visually follow the arc that is coming from the bottom of the cut. The arc should exit
the material at a slight angle away from the direction of travel. If it's going straight down, that means you're going too slow, and you'll have
an unnecessary buildup of dross or slag. If you go too fast, it will start spraying back onto the surface of the material without cutting all the
way through. Because the arc trails at an angle, at the end of a cut, slow your cutting speed and angle the torch in to cut through the last bit
of metal.
-
easiest way to reduce bevel is by cutting at the proper speed and height for the material and amperage that is being cut.
Correct torch height and square
to the material.
Minimum bevel & equal bevel
Longest consumable life
Torch angled to the material.
Unequal bevel, one side may be
excessively beveled.
Torch height too high.
Excessive bevel, plasma stream
may not cut all the way through
the material
Torch height too low.
Reverse bevel. Tip may
contact the work and short out
or damage the tip.

which maintains a narrow plasma stream at lower settings for use on thin-gauge material. Using a 25 amp tip at an 60 amp setting will blow
Electrons arc across the gap, ionizing and super
heating the air creating the plasma stream. The electrode contains an insert in the end made of a highly conductive material called hafnium.
This insert erodes with use and develops a pit in the end of the electrode, when the pit becomes too much poor quality cuts will result and
necessitate replacement of the electrode.
