I've been thinking about buying the PSI100K for outside soldering jobs. Can these be refilled from standard butane containers or must one buy the Weller? 73, Roger -- Remember the USS Liberty (AGTR-5

One thing that doesn't seem to be considered when planning this type of array is the ground loss resistance. This appears in series with the element and may prevent enough current flow to enable the

This is one of these questions that comes up periodically for which there is no simple answer. First, what do you mean by "ground resistance"? Electricians and power companies are mainly interested i

One of the problems is that "ground" means different things to different people. It's rather like using Ohms to describe resistance, reactance and impedance! Proper lightning protection involves more
