25A PLASMA ARC CUTTING MACHINE
PLASMA30i
IN TRODUCTION
The PLASMA30i is an inverter current power source machine, designed for cutting
electrically conductive materials (metals and alloys) using the plasma arc procedure. The
plasma gas may be air or nitrogen. The lightweight portable inverter plasma cutter has
many features that enable the user to easily cut most all metals.

MUST READ INSTRUCTIONS BEFORE USE
Read, understand and follow all safety messages
and instructions in this manual. Safety messages in
this section ofthe manual contain a signal word with
a three-part message and, in some instances, an
icon.
The signal word indicates the level of the hazard in
a situation.
DANGER
Indicates an Imminently hazardous Situation which,
if not avoided, will result in death or serious injury to
the operator or bystanders.
WARNING
Indicates a potentially hazardous situation which, if
not avoided, could result in death or serious injury
to the operator or bystanders.
CAUTION
Indicates a potentially hazardous situation which, if
not avoided, may result in moderate or minor injury
to the operator or bystanders.
IMPORTANT
Indicates a situation which, if not avoided, may
result in damage to the welding equipment.
Safety messages in this section contain three
different type styles.
• Normal type states the hazard.
• Bold type states how to avoid the hazard.
• Italic type states the possible consequences of
not avoiding the hazard.
An icon, when present, gives a graphical
description of the potential hazard.
Plasma Arc Cutting
DANGER
• Electric welding or plasma cutting cause ultra
violet rays and weld spatter
Bystanders will be exposed to ultraviolet rays
and weld spatter.
Wear welding helmet with appropriate shade
lens while using electric welders or plasma
cutters.
Do not allow bystanders while welding or
cutting.
Wear safety shield and protective clothing.
Ultraviolet rays will burn eyes; weld spatter can
cause injury.
WARNING
• Plasma cutting produces heat, sparks, hazard
of electric shock and/or hazardous vapors
Wear appropriate gloves, helmets or goggles
and other protective clothing.
Follow all instructions and safe practices while
welding or cutting.
Keep bystanders away from immediate area.
Byproducts of plasma cutting can cause burns or
other bodily injury.

Risk of Electrical Shock
WARNING
• Electrical shock can result when contacting
live electrode or internal components
• Electrical shock can result from absence of
grounding prong
Do not touch electrode or internal components
without protection.
Disconnect power before servicing.
Do not remove the grounding prong in any
electrical plug.
Electrical shock can cause injury
Risk of Explosion
WARNING
• Plasma cutting causes sparks that can cause
explosion
Use caution and proper procedures when
welding.
Avoid sparks if gasoline vapor and other fuels
are present.
Electrical shock, flames and explosion can cause
serious injury
Electrical and Magnetic Fields
WARNING
• Plasma cutting may cause localized Electrical
and Magnetic Fields around cables and power
sources
• The magnetic fields created by high currents
may affect the operation of medical
equipment.
Route the electrode and work cables together.
Do not place your body between the
electrode/torch and work cables.
Never coil the electrode/torch lead around
your body.
Do not work next to welding/cutting power
source.
Electrical shock and Magnetic fields can cause
injury.
Disposal of Equipment
IMPORTANT
• Disposal of electrical equipment can be
hazardous to the environment
Contact local regulations prior to disposal
Improper disposal can cause an environmental
hazard

EXPLANATION OF THE TECHNICAL
SPECIFICATIONS LISTED ON THE
MACHINE PLATE
EN 60974.1 The machine has been built according to
EN 50199 this European
standar
ds.
EN 50192
N°..................... Serial
number
.
Always indicate this for any request
regarding the machine.
....... Single-phase static
transformer-r
ectifier
frequency
converter
.
.................... Drooping
characteristic.
................. Suitable for plasma
cutting.
TORCH TYPE ......Type of torch that may be used with
this
machine.
U0.
PEAK ....
Secondary open-circuit voltage. Peak value.
X .....................
Percentage duty
cycle.
The duty cycle expresses the
percentage
of
10 minutes for which the machine may work
at a certain current I2 and
voltage
U2 without
overheating.
I2 ......................
Cutting
curr
ent.
U2 ....................Secondary voltage at cutting current I2.
This voltage is measured when
cutting
with the gas nozzle in contact with
the
work piece.
If this distance increases, the cutting
voltage also increases and the duty cycle
X% may drop.
U1 ....................Rated supply
voltage
1~ 50/60Hz ...... 50- or 60-Hz single-phase power
supply
.
The machine is equipped with
automatic
voltage change.
I1 Max ............. Max. absorbed current at the
correspon
ding
current I2 and voltage U2.
I1 eff ................This is the maximum value of the
actual
current absorbed, considering the
duty
cycle. This value usually corresponds
to
the
capacity of the fuse (delayed type)
to
be
used as a protection for
the equipment.
IP23 S . ............ Protection rating for the housing.
Grade 3 as the second digit means
that
this
equipment may be stored, but it is not
suitable for use outdoors in the rain, unless
it is protected.
S ...................
Suitable for working in hazardous
enviro
nments.
