Resistance welding over a lip, in a corner, or in a box might be a perfect application for a double bend electrode.
Above is a sketch showing an example of a double bend electrode welding in a tight area. There are many applications like this that a double bend full size electrode or double bend shank and cap will allow you to reach an otherwise difficult location to weld. Double bends can be water cooled to increase life. Double bends come in many offsets and sizes as shown below.
