2.2 Hand torch cutting technique.

When cutting make sure that sparks

are exiting from the bottom of the

work piece.

If sparks are spraying up from the

work Piece, you are moving the torch

too fast, or you don’t have enough

amps set.

Hold the torch vertical and watch the

arc as it cuts along the line.

2.3 Piercing.

Hold the torch at an angle to the work

piece, pull the trigger to start the arc

and slowly rotate it to an upright

position.

When sparks are exiting from the

bottom of the work piece, the arc has

pierced through the material.

When the pierce is complete,

proceed

with cutting.

2.4 Amperage

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.

2.5 Speed

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.

2.6 Direction

It is easier to pull the torch towards you than push it. 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 taken into consideration before starting your cut as you want the straight side of the cut to be

on the finished piece you keep.
