Clarke 052249011064, Operating Manual

This plasma cutter has been engineered to

give many years of trouble free service pro-

viding that a few very simple steps are taken

to properly maintain it.

1. Keep the unit clean and free of dust.

Periodically use dry, compressed air to

clean dust deposits from face plate and

vents

2. Check the water trap regularly. Drain

condensation before every use.

3. Keep the torch components free of slag

at all times. A clogged nozzle or elec-

trode will not allow proper airflow and

may damage the torch.

4. Keep consumables in good working con-

dition. Replace consumables as needed.

5. Form a regular habit of checking electri-

cal cable and torch cable. If any damage

is apparent, the cable should be replaced

immediately.

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 water trap 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 water trap 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 will 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 8)

1. After allowing torch to cool, 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 9).
