The volt-ampere curves show the
minimum and maximum voltage
and amperage output capabilities of
the welding power source. Curves
of other settings fall between the
curves shown.
Duty cycle is how long the unit can
operate within a ten minute period
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 CO
30% when using mixed shielding
gas.
