Section 1 Introduction and Specifications
DUTY CYCLE:
The duty cycle of this unit has been tested and established at 60% at full Amp Output. This duty cycle has been established under the standard
rating temperature of 104 F (40 C). If you are not familiar with Duty Cycle ratings, duty cycle is the percent of time out of a 10 minute time
period at which a welder or plasma cutter can operate continuously without overheating. Lowering output increases duty cycle. It is possible to
achieve a 100% duty cycle by lowering the output Amps. However, 100% duty cycle is still based off a 10 minute time period and does not
mean it has an “innite” duty cycle. Theoretically, if the machine were to go 11 minutes of uninterrupted operation even at a 100% Duty Cycle
level of operation, you could incur an overheat condition. Duty cycle on this machine is not controlled by a timer, but rather by one or more
temperature sensors strategically located on the heat sink(s) of the machines internal circuitry. If an overheat is detected the cutting output will be
interrupted. A code of “E01” will be displayed. If this happens, allow the unit to continue to run and cool for at least 15 minutes. Do not turn
the unit off during this time! If the unit does not automatically reset after this time, cycle the machine off and back on to clear the code. If the
code does not clear at this time, contact Everlast for further remedy. Intentionally and repeatedly triggering the duty cycle can damage the unit
over time. This type of damage becomes apparent during repair and service and is not covered under warranty.
CNC Use and Duty Cycle Concerns:
CNC use demands more out of plasma cutter than normal hand cutting operations. Always be aware of your Amp output level and use patterns
during CNC operation. If operating in CNC mode for thick, long cuts, or when doing repeated and rapid high input Amp demand activities, i.e.
rapid, successive starts, consider lowering the Amp output of the machine to at least the 100% duty cycle rating of this unit for best results. (See
page 10 for exact duty cycle specications). Of course this lowers maximum cut capacity, but it is also part of the reason why CNC cutting has
lower stated cut capacities across most all brands of plasma cutters.
Occasionally, you may exceed the duty cycle cutting through thick materials or with constant use. This usually causes no harm. However, if you
are regularly exceeding the duty cycle, this is a sign that you may need to use a larger plasma cutter or your unit may need to be cleaned and/or
serviced.
OVER/UNDER VOLTAGE/CURRENT:
This unit is equipped with a over/under voltage/current device which senses under or over voltage conditions caused by poor power supply or
internal faults and shuts down output. If you observe an error code “E02” immediately turn the machine off. Evaluate the input power supply for
proper voltage. Also inspect the suitability of any extension cords for service. If code does not clear, after remedying common issues stated
below, contact Everlast. Do not continue to try to clear the code if it does not appear to have been corrected.
Common Items That Can Trigger the Over/Under Voltage Current:
•Operating on too long or undersized extension cord or service wiring. Damaged wiring.
•Improperly grounded service/ power supply.
•Operating on too small of a generator or on a generator not rated as “Clean Power” (5% or less THD).
•Too long of a cutting arc.
•Excessively worn or missing consumables or damaged torch head.
•Internal machine fault. (If code cannot be cleared after correcting other issues, call Everlast.)
GENERATOR REQUIREMENTS AND OPERATION
This unit may be run on a generator. (See pages 10, 11, and 12 for respective generator wattage requirements.) However, the generator must
provide “clean power”. Clean power is dened as having 5% or less Total Harmonic Distortion (THD). This is a rating given by the manufacturer
of the generator, and not Everlast. This is similar to the power normally supplied at a wall outlet. This represents a sine wave (AC) that is most-
ly free of voltage spikes and electronic noise. Many general purpose (GP) generators are not rated to produce clean power and are designed for
emergency or construction use with resistive loads such as lights or heaters. These generators can damage the plasma cutter. If damage does
not occur immediately, the effect can be cumulative, depending on how “dirty” the power actually is. Damage created by running this unit off a
generator, or welder/generator not rated for clean power output by its manufacturer will not be covered under warranty. If you are in doubt about
your generator or welder/generator, contact the manufacturer. Everlast does not keep an authorized list of generator brands or models. Howev-
er, if the manufacturer rates its generator for 5% or less THD, this is sufcient to meet our standards. However, do some additional research on
the brand and model of the generator to make certain there are no issues, recalls or reported equipment (electronics in particular) damage related
to malfunctioning generators from the manufacturer.
The generator should be properly grounded, according to the generator manufacturer instructions.
Never leave the unit on or connected while starting the generator. Never stop the generator while the unit is on or connected. Severe damage
will occur. This includes running the generator low on or out of fuel. This damage is not covered under warranty, even if the unit is rated as
“clean powered”. Always allow the generator to warm up before plugging the unit in and using it. A cold engine may not develop or maintain
proper RPM needed to provide stable, clean power even if the unit is rated to be “clean power”. Never use economy idle (ECO mode), or auto
idle modes with this unit. Always use maximum idle when this unit is turned on.
