Note: What does the term “duty cycle mean?
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 cur-
rent. 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.
Operation
