WARNING
EXPOSURE TO A PLASMA ARC IS
EXTREMELY HARMFUL TO THE EYES
AND SKIN! Prolonged exposure to the plas-
ma arc can cause blindness and burns.
Never strike an arc or begin cutting until you
are adequately protected. Wear flameproof
welding gloves, a heavy long sleeved shirt,
cuffless trousers, high topped shoes and a
welding helmet.
3. Pull the trigger and release, and then
immediately pull the trigger again and hold.
4. Lower the tip of the torch to within 1/8
inch of the workpiece or until the main
cutting arc transfers to the workpiece and
sparks start.
4. If you intend only to pierce the workpiece,
release the trigger when the plasma
stream has penetrated the material.
5. For extended cuts, proceed to pull (or
push) the torch across the area to be cut
at a moderate, steady pace.
6. To shut the torch off, simply release the
trigger.
Note: When the trigger is released and the
arc is extinguished, compressed air will con-
tinue to flow for a short period, in order to cool
the torch. DO NOT switch off the machine
until the air has stopped flowing or damage to
the torch may occur.
RECOMMENDED CUTTING SPEEDS
The cutting speed necessary to produce
good, clean cuts depends on several vari-
ables: Material Type, Material Thickness,
Distance from the material to be cut,
Accuracy of the operator, Line voltage fluctu-
ations and a host of others. Table 3 offers
some general suggestions for cutting speeds,
assuming that all conditions are ideal. Actual
results may vary and it is recommended that
you practice your cuts before beginning work
on any valuable materials.
