The sparks from the gouging process can cause damage to
coated, painted or other surfaces such as glass, plastic, and
metal.
Check torch parts. The torch tip must be appropriate for
gouging operation. The torch electrode must correspond
with the plasma gas being used (air or multi-gas). See Tip
and Electrode Selection, page 16.
Be sure the operator is equipped with proper gloves,
clothing, eye and ear protection and that all precautions at
the front of this manual have been followed. Make sure
no part of the operator’s body comes in contact with the
workpiece when the torch switch is pressed.
WARNING
CAUTION
Plasma Gouging Operation
WARNING
Disconnect primary power to the system before
disassembling the torch, leads, or power supply.
Gouging performance depends on the torch travel speed,
the current level, the angle at which the torch is held to the
workpiece (lead angle), and the distance between the torch
tip and the workpiece (standoff). Gouging can be accom-
plished with either a hand or machine torch.
Optimum torch travel speed for gouging is between 20
and 120 inches per minute (0.5 and 3.0 meters per minute).
Travel speed is dependent on current setting, lead angle,
and mode of operation (hand or machine torch).
Current settings depend on torch travel speed, the mode
of operation (hand or machine torch), and the amount of
material to be removed.
