John Ward shows us his new test device. Not exactly a bench mounted piece of gear! This Oil Filled Oxford Welder can be used in cases where you need to pump out some serious current, this is ideal to test to destruction items such as wires, extension cables, plug in connections etc. JW has performed many of these tests in the past. Photonicinduction has taken a look at the inside of one of these in the typical over the top fashion. This thing is built like a tank, not sure what the working duty cycle is but I wouldn’t be surprised if it wasn’t 100% at most settings.
Power cords typically use copper as the conductors, the copper would represent a large portion of the cost so if a company wants to shave some of the production cost down goes the conductor diameter. Check out the junk power cord that John Ward tests to destruction below.
