Duty Cycle Rating
Cutting duty cycle is the percentage of actual cutting time that
can occur in a ten minute cycle. E.g. 20% at 40 amps - this means
the plasma cutter can operate at 40 amps for 2 minutes and
then the unit will need to be rested for 8 minutes. All duty cycle
ratings are based on an ambient air temperature of 40°C with
50% humidity, which is the international standard for such a rating.
In an environment with temperatures exceeding 40°C, the duty
cycle will be less than stated. In ambient temperature less than
40°C, duty cycle performance will be higher.
QUICK START GUIDE
PLASMA CUTTER INSTALLATION
Electrical Connection
The EZICUT 40 and ADVANCECUT 40 are designed to operate
on a 15A 230V AC power supply.
The AdvanceCut Multivoltage technology (not including EZICUT
40) allows the machine to operate on a very wide range input
voltages down as low as 90V. This means that limited capacity
power supplies and long extension leads may be used without
damaging the plasma cutter.
However, as the supply voltage decreases, the maximum output
current and duty cycle will also decrease. To utilise the full output
capacity of the machine using an extension cord, it should be a
heavy duty version with a minimum cable core size of 2.5mm2.
It is recommended to use the Euroquip industrial duty 15A
extension lead, part number; 16895.
The EZICUT 40 does not have PFC/ multivoltage technology.
This means if an extension cord must be used, it should be a
heavy duty version with a minimum cable core size of 2.5mm2.
It is recommended to use the Euroquip industrial duty 15A
extensionlead, part number; 16895.
Compressed Air Requirements
A reliable and consistent supply of clean dry compressed air is
essential for proper operation. Although the machine contains
its own internal air supply filtration system it is recommended the
compressed air supply should have external filtration in the line
feeding the machine, both a standard water trap (sintered bronze
filter) and also a coalescing filter (for oil in air). The air requirement
is a minimum of 120 l/min (4.5cfm) Free Air Delivery (FAD) at 75psi
pressure. This normally means the compressor must be a belt
drive model or if a direct drive it must have a motor power of
2.5HP or greater.
The air must be dry and free of oil and moisture (normally a
symptom of older, worn out compressors). The air hose must also
be of sufficient size (3/8”/10mm minimum) to supply the machine

Operating Environment
Adequate ventilation is required to provide proper cooling for the
DURALLOY CUT 40PFC MV. Ensure that the machine is placed on
a stable level surface where clean cool air can easily flow through
the unit. The has electrical components and control circuit boards
which may be damaged by excessive dust and dirt, so a clean
operating environment is important for reliable product life.
BASIC OPERATION
1.1 Connect the earth cable quick connector to the earth
connection socket (7) Connect the earth clamp to the work
piece. Contact with the work piece must be firm contact with
clean, bare metal, with no corrosion, paint or scale at the
contact point.
1.2 Connect the plasma torch to the machine central connector
(8) ensuring the collar is done up firmly.
1.3 Connect the machine to suitable mains power using the mains
input power lead. Switch the mains power switch to ‘on’ to
power up the machine.
1.4 Connect the compressed air supply to the filter/ regulator inlet
(11). Check the air pressure (10). Trigger the air flow using the
‘set’ function (6), check the air pressure again and adjust if
necessary. Return the switch to ‘run’ position.
1.4 Select the output current using the current control knob (1).
You are now ready to plasma cut!
