4-6 Dutry cycle
No matter how tough a person may be, he will be exhausted if he keeps working without rest. This
welder is not of a design that withstands continuous use when it is used as a welder, from the viewpoints
of job contents and economy.
Duty cycle indicated below explains this situation. It is the same for manual welding.
* Usage rate represents the ratio of the load time in a 10-minute period. Usage
rate 50%, for instance, means no-load running for 5 minutes after load running
(welding) for 5 minutes.
[Caution] : Be careful so that overload will not occur, referring to the following table.
