OPERATION
PLASMA CUTTER
Piercing thickness is dependent
on the output of the machine
and is generally 50% of the
rated cutting thickness of the
power source.
It is important to direct the
arc away from the operator
when establishing the arc as
sparks and molten material will
be ejected from the point of
contact. Care must also be taken
Fig.4
to protect the surrounds from
these sparks.
7.4 QUALITY CUTS
Dross (slag) is the excess material that spatters and builds up on the underside
of the work-piece as you cut. Dross occurs when the operating procedure and
technique is less than optimal. It will require practice and experience to obtain
cuts without dross. Although less than optimal cuts will contain dross, it is
relatively easy to remove by breaking it off using pliers or chipping off with a
chisel or scraping or grinding the finished cut as needed and is generally only a
minor inconvenience.
A combination of factors contribute to the buildup of dross. They include
material type, material thickness, amperage used for the cut, speed of the torch
across the work-piece, condition of the torch tip, air pressure, etc. Generally
there is an inversely proportional relationship between output current and
speed of cut. Do not use more output current than is necessary and adjust
speed of cut toward minimizing dross buildup on underside of cut. Experiment
with adjusting current and speed to minimize dross.
7.5 THERMAL PROTECTION
This plasma cutter is automatically protected from overheating by a thermal
overload cut out protector The over temperature lamp (3) will illuminate to
show that the cut out has operated. After cooling the protector will reconnect
the supply circuit and the cutter will be ready for further use.
