Gas welding (GMAW) uses wire and gas to form an electric arc for heating and melting metal. Alternatively, in stick welding (SMAW), you hold a stick with an electric current to make welds. Another type of welding, flux-cored arc welding (FCAW), uses flux to generate heat. The best tr...
it will not necessarily protect you from the heat. Proper positioning during welding can keep the heat away from you to some degree. Better protection can come from a leather welding jacket orapron. Not only will this keep much of the radiation off of you, but it will also help protect...

So, if the size of the action potential does not vary, how does an action potential code information? Information is encoded by the frequency of action potentials, much like FM radio. A small stimulus will initiate a low frequency train of a few action potentials. As the intensity of the ...
