duty cycle
duty cycle is a welding equipment
specification, which defines the number of
minutes, within a 10-minute period, during
which a given welder can safely produce
a particular welding current. For example,
this 90 amp welder with a 10% duty cycle
must be rested for at least 9 minutes after
1 minute of continuous welding.
Failure to carefully observe
duty cycle limitations can easily over
stress a welder’s power generation
system contributing to premature
welder failure. Many welders do not
have internal protection systems
that prevent this sort of over stress
-- leaving the task to the owner or
operator.
