When comparing the heat input of spray mode transfer to that of pulse transfer you need to know the particulars of each.

Heat input is usually calculated as voltage times amperage time 60 divided by the travel speed.

This calculation is pretty direct for the spray transfer mode. You know the amperage, voltage, and travel speed.

However, pulse transfer involves more variables. Peak amperage, background amperage, duration of the pulse and the frequency of the pulse. Few machines provide information on all the pulse variables. Some machines provide average voltage and average amperage. The travel speed is a direct measurement. The average ampeage, voltage, and travel speed can be used to calculate the heat input.

I can use a peak amperage and long pulse duration that will result in nearly the same heat input as a simple spray mode transfer od I can reduce the heat input by using a short duration for each pulse and reduce the heat input.

The Lincoln PowerWave series allows the pulsing parameters to be monitored and provides the "power input" which can be used to calculate the heat input. You will need a laptop computer and software, but you can do it.

Now you to can go screaming into the night!

Good luck - Al
