V1.0
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.
• At the end of a cut slow your cutting speed and angle the torch
forward to cut through the last bit of metal.
DIRECTION
Pull the torch towards you instead of attempting to push it away while
making a cut. The plasma stream swirls as it exits the tip, biting one
side and finishing off on the other leaving a bevelled edge and a
straight edge. The bevel cut effect is more noticeable on thicker material
and needs to be taken into consideration before starting your cut, as
you want the straight side of the cut on the finished piece that you keep.
TORCH TIP HEIGHT & POSITION
The distance and position of the plasma torch cutting tip has an effect on
the quality of the cut and the extent of the cut's bevel. The easiest way to
reduce bevel is by cutting at the proper speed and height for the material
and amperage that is being cut.
1. Correct torch height and square to the material. Minimum bevel &
equal bevel. Longest consumable life (Fig. 9).
2. Torch angled to the material. Unequal bevel, one side may be
excessively beveled (Fig. 10).
3. Torch height too high. Excessive bevel, plasma stream may not cut
all the way through the material (Fig. 11).
