amount of time (expressed as a percentage) out of 10
minutes the unit can weld without a rest. For MIG, the
unit is capable of welding 4 minutes out of every 10
minutes at the maximum output of 200 Amps. For the
balance of the 10 minute period, the unit should be
allowed to rest and cool while running. This rating is
based off a 40° C maximum temperature. If the unit
’
s
duty cycle has been exceeded, the Stop LED will come
on and unit will cease welding output. An error code of
“
E04
”
will be displayed If a duty cycle event has oc-
curred. Allow the unit to run and cool for 15 minutes.
After 15 minutes of cooling the unit while switched on
without welding, cycle the power switch to reset the
unit. In the event of an overcurrent, the welding out-
put will cease and the
“
Stop
”
LED will come on and an
error code of EO2 will be displayed. In duty cycle and
overcurrent events, the wire may continue to feed with-
out output. Overcurrent events can be caused by too
low of supply voltage, running on undersized extension
cords, too large of welding wire diameter, too high of
settings for wire diameter, too high of input voltage, or
internal or external electrical fault. When an overcur-
rent has occurred, turn the machine off immediately,
then check and remedy the fault before switching the
welder back on. Under or over voltages will also trigger
the Stop LED. The error code of E01 will be displayed.
This is likely a result of a poor power supply, a long ex-
tension cable, or from running off of a generator that is
malfunctioning.
Note: If a generator is going to be used with this unit,
please make sure that it is certified by it
’
s manufactur-
er to be
“
clean power,
”
which is normally stated as
less than 5% THD ( Total Harmonic Distortion). For
proper operation with a generator, make sure you
have at least a minimum 8,000 watts of surge capabil-
ity and 6500 watts of continuous rated output capabil-
ity while operating on 240V.
