What is a 50% duty cycle?
When ever you are operating an American Beauty Resistance Soldering power unit at 50% of its available output, or higher, you will need to cycle the unit so that the idle time is equal to, or greater than the active time. For example, if your power unit is set to 50% and it takes ten seconds to solder a joint, you will need ten seconds or more of idle time before soldering the next joint. This is to ensure the power unit is not over taxed and to help keep the handpiece from over heating. You should periodically check the handpiece and cabling for any excess accumulation of heat. You should never run the unit continuously on any setting for more than 20 seconds.
