Duty Cycle In Welding Define Welding Cycle

Hallo ! Welcome to the a site all about welder, This a site was created as a means to provide a variety of instructions, especially relating to welder actions. on this occasion me will explain circa"Duty cycle in welding" plainly, get moving see more...

Duty cycle in welding

Duty Cycle means “how long something will work for before it overheats”.

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: a 250 amp. Welding machine with a 30% duty cycle must be “rested” for at least 7 minutes after 3 minutes of continuous welding.

Formula for the Estimation of Duty Cycle other than rated outputs:


Example: 200 Ampere Power Source rated at 60% Duty Cycle and operated at 250 Ampere (as far as permitted):


This means that the power source has to be operated maximum 3.8 minutes with a current of 250 Ampere (according to the 10 minute cycle).

Formula for the Estimation others than rated output currents at a specified Duty Cycle:


Example: The maximum output current at a duty cycle of 100% (according to 10 minutes duty cycle) can be calculated by:
