C. Optional Single-Stage Filter Element
Replacement
NOTE
The Power Supply shuts down automatically when
the Filter Element becomes completely saturated.
The Filter Element can be removed from its hous-
ing, dried out, and reused. Allow 24 hours for El-
ement to dry.
1. Remove power from power supply.
2. Shut off air supply and bleed down system be-
fore disassembly to change Filter Element.

3. Disconnect gas supply hose.
4. Turn the Cover counterclockwise and remove it
from the Filter Housing. The Filter Element is lo-
cated inside the Housing.
5. Remove the Filter Element from the Housing and
set Element aside to dry.
6. Wipe inside of housing clean, then insert the re-
placement Filter Element cup side first, as shown
below.
7. Replace Housing on Cover.
8. Reattach gas supply hose.

5.03 Common Operating Problems
WARNINGS
Disconnect primary power at the source before dis-
assembling the power supply, torch, or torch leads.
Frequently review the Important Safety Precau-
tions (page 1). Be sure the operator is equipped with
proper gloves, clothing, eye and ear protection.
Make sure no part of the operator’s body comes into
contact with the workpiece while the torch is acti-
vated.
CAUTION
Sparks from the cutting process can cause damage
to coated, painted, and other surfaces such as glass,
plastic and metal.
NOTE
Handle torch leads with care and protect them from
damage.
A. Piloting
Piloting is harder on parts life than actual cutting because
the pilot arc is directed from the electrode to the tip rather
than to a workpiece. Whenever possible, avoid excessive
pilot arc time to improve parts life.
B. Torch Standoff
Improper standoff (the distance between the torch tip and
workpiece) can adversely affect tip life as well as shield
cup life. Standoff may also significantly affect the bevel
angle. Reducing standoff will generally result in a more
square cut.
C. Edge Starting
For edge starts, hold the torch perpendicular to the work-
piece with the front of the tip at the edge of the work-
piece at the point where the cut is to start. When starting
at the edge of the plate, do not pause at the edge and
force the arc to "reach" for the edge of the metal. Estab-
lish the cutting arc as quickly as possible.
D. Direction of Cut
In the torch, the plasma gas stream swirls as it leaves the
torch to maintain a smooth column of gas. This swirl ef-
fect results in one side of a cut being more square than
the other. Viewed along the direction of travel, the right
