Getting Started
CONNECT THE AIR COMPRESSOR
What do I need to be able to plasma cut?
The unit comes with everything you need as far as a basic starter kit
for consumables, torch and regulator. However, you will need to
supply a few things on your own.
1.
You will need a suitable air
-
compressor and at least
3/8”
supply
line hose. By suitable, we mean one of at least 30 gallon capac-
ity, with at least 5.3 CFM @ 90 PSI. This size air
-
compressor
usually is available as an oil type which has a oil sump for
lubrication for long life and improved cooling. 6CFM @ 90PSI
and a 60 gallon tank is even better, but not required. A 30
gallon compressor is usually 120V, but larger compressors are
240V. If it uses 240V, you will need a separate circuit for your
air compressor. Your welder and air
-
compressor should not
share the same circuit, or be
“
piggy backed
”
at the panel or
receptacle. Get a licensed electrician to assess your needs, to
make recommendations and to install the circuit if needed.
2.
You will need to be able to regulate your air at the air compres-
sor. Do not use the pressure switch on the air compressor to
control the air pressure. A gate or ball valve installed on the air
compressor is not enough either. You will need an adjustable
regulator which will control the air pressure at the tank. The
regulator that you install on the unit is to be used to regulate
actual cutting pressure. You need to be able to regulate the
supply pressure down to 90PSI at the air
-
compressor. If you
supply more than 100PSI to the cutter
’
s regulator, you may
damage the regulator.
3.
You will need a separate air
-
dryer. Moisture is the enemy of
any plasma system and destroys consumable life and eventually
torches themselves. The regulator/filter included with the unit
is not sufficient to remove moisture from the system. It is de-
signed to trap particulates and slugs of water created by the
coupling/decoupling process. A refrigerated system is not
necessary. We recommend you look at the cartridge type sys-
tems that have replaceable elements for a budget alternative. If
these are not available, consider at least having a replaceable
paint gun dryer mounted inline and monitor the moisture it
traps and replace it often.
4.
You may need additional consumables with different sizes to
match the cut Amperage. The stock consumables are designed
for use at the maximum amperage of the machine. The orifice
in the plasma tip is specifically designed for a range of Amps.
To see that range, check the plasma torch page of this manual,
and each tip diameter corresponds to a specified amp range.
Lowering air pressure to try to compensate for lower Amps
results in poor quality cuts and inconsistent arc behavior. Al-
ways match the consumable size to the Amperage being used.
IMPORTANT:
Do not reverse air flow direction! Make sure the arrow stamped on top
of the regulator coincides with the direction of air flow.
