DRAINING CONDENSATION
Keeping a clean, dry air flow to your plasma
cutter is essential for reliable, trouble free
service. By regularly draining condensation
from the Air Filter you will promote a longer
life for consumable parts.
Note: If your plasma cutter will not be used
for extended periods of time, disconnect it
from the air supply.
1. Slowly turn the knurled drain valve on the
bottom of the Air Filter housing counter-
clockwise (as viewed from bottom of unit)
until it is fully open.
2. Allow all condensation to drain.
3. Retighten drain valve.

REPLACING THE NOZZLE
During the cutting process, the parts on the
end of the torch are slowly consumed. To
prevent premature consumption of some
torch parts and to prevent damage to the
torch itself, it is necessary to replace the
consumable parts in a timely manner.
If your cuts begin to appear jagged, or the
cutting arc becomes difficult to maintain, it
may be necessary to change the nozzle. A
quick visual inspection wilt reveal whether a
nozzle is worn. The hole in the tip of a good
nozzle is round. Once the hole takes on an
elongated, or elliptical shape it is necessary
to replace the nozzle. (See Figure 10)

1. After allowing torch to coot, remove the
nozzle cap from the torch by turning it
counterclockwise.
2. Remove the worn nozzle.
3. Place new nozzle onto electrode.
4. Replace nozzle cap by firmly turning it
clockwise onto torch assembly (refer to
Figure 11).
