What is Plasma Cutting and What are Plasma Cutter
Consumables?
Plasma cutters have the capability to cut the
metals in simple and complex shapes like holes,
edges, markings, etc. Plasma cutters are
cost-effective and practical compared to
oxy-fuel, laser, and water jet cutting processes.
Let us understand how plasma cutters work and
what consumables you will need.
What is Plasma Cutter? Plasma cutting is a
cutting technique that uses an accelerated jet of
hot plasma to cut through conductive metals like
steel, aluminum, brass, titanium, copper, etc. It
is widely used in manufacturing, automotive
repair, industrial construction, restoring,
scrapping, etc. Plasma cutting can be done using
a handheld plasma torch also known as plasma
arcs, guns, or cutters. For that, you will need
hand held plasma cutter parts. Due to high speed,
precise cuts, and low cost, plasma cutting is
widely used by small companies and industries
using CNC.

Why You Need Plasma Cutter Consumables?
Using plasma cutter over time, components start
wearing off gradually. Worn consumables can ruin
metal while cutting. Your operator can tell which
consumables are worn by sound, color, etc.
The best way to keep a check on the condition of
your consumables is to periodically inspect
consumables. If you see that the quality of the
cut is deteriorating, you have an indication that
it needs to be changed.
It is a good practice to maintain a record of the
average life of parts over time and prepare a
guideline for consumables based on the thickness
of the material, amperage, and material. So
operator will know after what time he needs to
check the components thoroughly to prevent
catastrophic failure.
It is essential that you run all your parts at
the correct amperage. High or low amperage can
impact the cut quality. However, using incorrect
consumables can also lead to shortened life and
cut quality.

List of Consumables With Their Purpose
You can choose from different consumables like
Hypertherm powermax 45 consumables, Powermax 45
XP, Powermax 65, etc. Here is the list of the
consumables you might need.
Electrode The electrode provides power to the
plasma arc. Electrode conducts high voltage or
high-frequency energy while you start the cut.
This adds energy to ionize the cuttings gas that
creates plasma and allows the arc to start.
Swirl Ring A swirl ring is made of ceramic or
volcanic ash. It controls and swirls the plasma
gas around the electrodes and inside nozzles. It
basically controls the point where the arc is
attached to the emitter and also the plasma flow
through the nozzle that affects the edge
angularity. It usually swirls in clockwise
rotation but their counterclockwise swirls are to
assist for mirror cutting.

Nozzle Nozzle constricts the gas stream flowing
through the orifice in the center of the nozzle.
A nozzle that is worn out or improper will cause
the part to have an improper size or edge. The
orifice must be a circle and not oval or
egg-shaped.
Inner Retaining Cap The purpose of the retaining
cap is to hold all the internal stack components
in proper alignment. A damaged or improper
retainer will cause the rest of the consumables
to fit improperly and it can cause a gas error,
coolant leaks, or poor cut quality.
Shield Cap As the name suggests, a shield
protects all the consumables from sparks and
molten metals. There are mostly made of copper
and provide a proper distance between nozzle and
workpiece.

Water Tube It works as a coolant to the tips of
the electrodes to prevent overheating. The size
of the tube is important otherwise it will cause
premature electrode failure due to overheating.
Conclusion
It is important to invest in a good-quality hand
held plasma cutter parts. Because poor quality
will have less shelf-life. You can find different
Hypertherm consumables like Hypertherm powermax
45 consumables. powermax 45XP, powermax 65, etc.
easily from certified suppliers.
