they are being moved so equipment can be taken in and out more easily, as work is being done on the road.
One reason I've been busy is some classes going on at our church; fun summer stuff. One class the kids made dolls like this. Isn't that the coolest thing ever? I am the photographer for the classes, plus next week I will teach a photography class. To 8-11 year olds. Feel free to toss me ideas. I have only a partial lesson plan, but getting there!
I can never remember what this is supposed to signal. Gangs? Broken
hearts? Hobos?
This is right at my usual Muni stop, so I guess I'd better start
bracing myself for whatever gang war/breakup/hobo convention is about
to go down.
The inert gas and wire come into the black tube emerging from the top box which is the wire feeder. The wire and gas come out of the welding gun which is laying near the bottom of the power source box at the end of the black tube. The inert gas tank source at the left goes on a shelf behind the power source box.
I wound the transformers to get the correct voltage and arranged several of them together to get an amperage of 320 amps.
The wire feeder can be used with any power source including my gas powered Hobart portable welder.
The two boxes to the right are a 120 amp plasma cutter and a current regulator for tig welding with a foot pedal for control--all of which I made also. I didn't finish the plasma cutter since I didn't want to buy the nozzle parts. I could not make my own that were good enough.
As with many other of my electronic projects, I got almost all the electronic parts from the surplus of the closing of Heath Kit in town. The surplus store also has since closed.
