The volt-ampere
curves
show the
minimum and maximum
voltage
and amperage
output capabilities
of
the welding
power
source.
Curves of other
settings fall be
tween
the
curves
shown.
Duty cycle is how
long the unit
can
operate within
a
ten minute
penod
without causing
overheating
or
damage.
This unit is rated
at
20%
duty cycle
allowing welding 2 minutes out of
every
10 minutes.
This gun is rated at 60%
duty cycle
when
using CO2 shielding
gas
and
30% when using mixed shielding
gas.
