Rated Duty Cycle given Actual Duty Cycle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rated Duty Cycle = Required Duty Cycle*(Maximum current new add/Rated Current)^2
%_Rated = %_Required*(I_max/I_r)^2
This formula uses 4 Variables

Variables Used

Rated Duty Cycle - Rated Duty Cycle is the percentage of time in a 10 minute period that a welding machine can be used at its rated output without overloading.
Required Duty Cycle - Required Duty Cycle or Actual Duty Cycle is the percentage of time in a 10 minute period that a welding machine can be used at its rated output without overloading.
Maximum current new add - (Measured in Ampere) - Maximum current new add is the maximum possible current flow in the given situatiion.
Rated Current - (Measured in Ampere) - Rated Current is that value which is provided against standard operation of equipment by the manufacturer.

STEP 1: Convert Input(s) to Base Unit

Required Duty Cycle: 0.42 --> No Conversion Required
Maximum current new add: 7 Ampere --> 7 Ampere No Conversion Required
Rated Current: 4.5 Ampere --> 4.5 Ampere No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

%_Rated = %_Required*(I_max/I_r)^2 --> 0.42*(7/4.5)^2

Evaluating ... ...

%_Rated = 1.0162962962963

STEP 3: Convert Result to Output's Unit

1.0162962962963 --> No Conversion Required

FINAL ANSWER

1.0162962962963 ≈ 1.016296 <-- Rated Duty Cycle

< 11 Heat Input in Welding Calculators

Net heat supplied to joint

Go Heat Required per Unit Volume = Heat Transfer Efficiency*Electrode Potential*Electric Current/(Melting Efficiency*Travel Speed of Electrode*Area)

Heat required to Melt Joint

Go Heat Required = Mass*((Specific Heat Capacity at Constant Pressure*Rise in Temperature)+Latent Heat of Fusion)

Total heat generated in resistance welding

Go Heat Generated = Constant to Account for Heat Losses*Input Current^2*Resistance*Time

Rated Duty Cycle given Actual Duty Cycle

Go Rated Duty Cycle = Required Duty Cycle*(Maximum current new add/Rated Current)^2

Required Duty cycle for arc welding

Go Required Duty Cycle = Rated Duty Cycle*(Rated Current/Maximum current new add)^2

Net heat per unit volume available for Arc welding

Go Heat Required per Unit Volume = Input Power/(Travel Speed of Electrode*Area)

Heat Transfer Efficiency

Go Heat Transfer Efficiency = Net Heat Supplied/Heat Generated

Power given Electric Potential Difference and Electric Current

Go Power = Electric Potential Difference*Electric Current

Power given Electric Potential Difference and Resistance

Go Power = (Electric Potential Difference^2)/Resistance

Melting Efficiency

Go Melting Efficiency = Heat Required/Net Heat Supplied

Power given Electric Current and Resistance

Go Power = Electric Current^2*Resistance

Rated Duty Cycle given Actual Duty Cycle Formula

Rated Duty Cycle = Required Duty Cycle*(Maximum current new add/Rated Current)^2
%_Rated = %_Required*(I_max/I_r)^2

What is rated duty cycle?

The rated duty cycle is the percentage of time in a 10 minute period that a welding machine can be used at its rated output without over loading, under rated specifications given by manufacturer.
Most of the welding machines need not have to operate the full time, since a good length of time is spent in setting up, metal chipping, cleaning and inspection. Normally, a 60% duty cycle is suggested.

How to Calculate Rated Duty Cycle given Actual Duty Cycle?

Rated Duty Cycle given Actual Duty Cycle calculator uses Rated Duty Cycle = Required Duty Cycle*(Maximum current new add/Rated Current)^2 to calculate the Rated Duty Cycle, The Rated duty cycle given actual duty cycle can be calculated by considering the required duty cycle formula along with max. current and rated current at rated duty cycle. Rated Duty Cycle is denoted by %_Rated symbol.

How to calculate Rated Duty Cycle given Actual Duty Cycle using this online calculator? To use this online calculator for Rated Duty Cycle given Actual Duty Cycle, enter Required Duty Cycle (%_Required), Maximum current new add (I_max) & Rated Current (I_r) and hit the calculate button. Here is how the Rated Duty Cycle given Actual Duty Cycle calculation can be explained with given input values -> 1.016296 = 0.42*(7/4.5)^2.

FAQ
