Cut with the Hand Torch

Shielded versus non-shielded consumables
Non-shielded consumables use a deflector instead of a shield. They can provide better
visibility and accessibility for some cutting applications. The trade-off is that
non-shielded consumables generally have a shorter life than shielded consumables.
Thickness of metal being cut
In general, the thicker the metal being cut, the more quickly the consumables become
worn. For best results, do not exceed the thickness specifications for this system. See
page 22.
See page 154 for guidelines on when to replace worn consumables.
Expanded metal cutting
Expanded metal has a slotted or mesh pattern. Cutting expanded metal wears out
consumables more quickly because it requires a continuous pilot arc. A pilot arc occurs
when the torch is fired but the plasma arc is not in contact with the workpiece.
Incorrect consumables for output current and mode
To optimize consumable life, make sure the consumables installed on the torch match
the selected mode and output current. For example:
Do not use gouging consumables when the system is set to Cut mode. See
page 51.
Do not set the output current between 26 A and 45 A with the Precision gouging
consumables installed.
Unnecessary arc stretch when cutting
To maximize consumable life, avoid stretching the arc when it is not necessary. Drag the
torch on the workpiece whenever possible. See page 66.
Insufficient arc stretch when gouging
A proper arc stretch while gouging maintains distance between the torch tip and the
molten metal that builds up during the gouge. See page 75.
An arc stretch of 19 – 25 mm (3/4 – 1 inch) is recommended for gouging with the
Maximum Control gouging consumables at 26 – 45 A.
An arc stretch of 10 – 11 mm (3/8 – 1/2 inch) is recommended for gouging with the
Precision gouging consumables at 10 A– 25 A.
