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 150 amp. welder with a 30% duty cycle must be "rested" for at least 7 minutes after 3 minutes of continuous welding.

In other words, if the duty cycle is rated at 60%, then the machine works 60% of the time and turns off for 40%. The "on time" for a 60% duty cycle depends on the length of the period; it could be a second, a day, or a week… etc. Groschopp Duty. When choosing a fractional horsepower motor, customers typically have a speed, torque, and power load point they need the motor to deliver. This is a good starting point and a critical step in the process of choosing the correct motor for an application. However, duty cycle can often be overlooked, Duty cycle, a term typically used as a rating for electric motors, is the time a compressor runs compared to the total cycle time (total time running and stopped). For example, a compressor with a total cycle time (Tc) of 10 minutes and a running time (Tr) of six minutes has a duty cycle of 60 percent. The name also suggests it (211), yet the rated output for duty cycle purposes is 150 amps. If one hears that this machine has a duty cycle of 30% they may assume 30% at full output. They would quickly find out that at 210 amps the duty cycle is much lower. As a result, the CMAA (Crane Manufacturers Association of America) has established a duty cycle rating system that ranges from a Class “A”-Standby Service to a Class “F”-Continuous Duty, to measure the amount of work to be performed by the crane. It consist of a somewhat confusing combination DUTY CYCLE: Reciprocating air compressors are designed to operate in an on/off or cyclical manner. The relationship between on time and off time is called duty cycle. All compressors are rated for a specific duty cycle, such as 50/50 or 75/25. Los Angeles, CA – (April 30, 2015) Simply put, duty ratings define the power and annual hours of usage that are expected of an engine. More specifically, a duty rating for marine engines is the power available under normal varying electrical load factors for an unlimited number of hours per year in commercial applications.

Duty Cycle is a term that is used (related to air compressors) that tells you how long the compressor is rated to run for versus how long it should rest and an overall gauge for how "heavy duty" the motor is (in general).

18 May 2018 it does have a pretty crummy duty cycle rating. Depending on the process, it's as low as 25%, with is 2.5 minutes of welding with 7.5 minutes  If the actual motor installation and use exceed its rated duty cycle you can expect the pump life to be reduced accordingly. Our photo at left shows a Meyers 2-line  Rated Output AC: 225 A at 29 V, 30% Duty Cycle. DC: 175 A at 27 V, 50% Duty Cycle. Max. Open-Circuit Voltage AC: 70. DC: 79. Light Industrial Applications. 26 Aug 2018 Duty cycle rating for a linear actuator is generally expressed as a percentage of “ on time” (the ratio of on time to total time) or as distance  (a) Test handheld engines with the following steady-state duty cycle: G3 mode No. Engine speed, Torque (percent), Weighting factors. 1, Rated speed, 100, 0.85.

22 Mar 2019 A printer duty cycle or monthly duty cycle is the absolute number of pages that can be printed per month at the rated print quality of a machine.

Duty Cycle is a term that is used (related to air compressors) that tells you how long the compressor is rated to run for versus how long it should rest and an overall gauge for how "heavy duty" the motor is (in general). Duty cycle is the proportion of time during which a component, device, or system is operated. The duty cycle can be expressed as a ratio or as a percentage. Suppose a disk drive operates for 1 second, then is shut off for 99 seconds, then is run for 1 second again, and so on. Duty cycle, a term typically used as a rating for electric motors, is the time a compressor runs compared to the total cycle time (total time running and stopped). For example, a compressor with a total cycle time (Tc) of 10 minutes and a running time (Tr) of six minutes has a duty cycle of 60 percent. Duty cycle, sometimes called "duty factor," is expressed as a percentage of ON time. A 60% duty cycle is a signal that is ON 60% of the time and OFF the other 40%. Many loads are rapidly cycled on and off by a fast-acting electronic switch which accurately controls the output power of the load .

8 Nov 2010 Unless otherwise specified, the rating of the motor will be regarded as its continuous maximum rating (CMR), defined by duty S1. But a machine 

In the printer / copier industry, the duty cycle specification refers to the rated throughput (that is, printed pages) of a device per month. In a welding power supply, the maximum duty cycle is defined as the percentage of time in a 10-minute period that it can be operated continuously before overheating.

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 150 amp. welder with a 30% duty cycle must be "rested" for at least 7 minutes after 3 minutes of continuous welding. Duty Cycle is the number of minutes out of a 10-minute period a welder can operate continuosly. According the spec sheet for the Millermatic 211 as published on Miller Electric’s site this machine has a duty cycle of 30% at a rated output of 150A on 230VAC input power. If no otherwise specified, the duration of a duty cycle shall be 10 minutes and the cyclic duration factor shall have one of the following values: 15%, 25%, 40%, 60%. The cyclic duration factor is defined as the ratio between the period of loading, including starting and electric braking,
