Now I'll use these 60 USB supplies to see if I can weld!
I've got one more experiment to try with the 60 USB supplies. Can I actually weld with them? This video has the supplies connected for 30V, 20A operation and shows some of the tests I did.
Consider this: General-purpose welders produce alternating current, while these supplies produce direct current. In an AC plasma, the net force to charged particles is zero, but with DC, the particles will tend to move one way or the other. I was surprised that the effect is big enough to be seen on the video.
Have a look!
And if it seems as though engineering is out the window for this one, don't worry. I've got some posts lined up for the future that get back to design. I just couldn't resist playing with arcs again (check out my previous experiment).
I also got a chance to try out our new Xcelite Ergonomic Screwdriver Set while making this video. I was using the big #2 Phillips and just kept thinking to myself, "Oh wow, these are nice." They have well-shaped handles, and the tips fit the screws perfectly. If you've been using the same crusty screwdrivers passed down for generations, it's time to treat yourself. Throw those old, smelly screwdrivers in the kitchen drawer!
Keep on sparkin',
