Step 1: General Componants
The general principle is the carbon rods need to be touched together and once they generate a glow and some heat parted slightly to instigate the arc.
Almost all examples I could find used a BBQ tong style handle although one example which showed how to make one running directly off the wall socket used a sliding handle and this was the basis of my design.
So I needed the carbon arc rods, my arc welder and a slide which is a metal draw runner from this I layed out my setup and added parts as I saw fit.
Step 2: Rod Holder
I wanted to use the stinger (electrode holder) for the arc welder as my main base and have the other parts detachable in order to use some or all parts as required.
My arc welder came with a spot welding attachment so I used a short length of steel tubeing that I ran a drill bit through to clean and make the correct size to take the carbon rod and an 3mm set screw which was spot welded together this then is held with the electrode clamp.
Step 3: Rod Clamps
To clamp the rod in place I drilled a 17mm AF nut to the size of my rod tube I then cross drilled it and through the tube and threaded the side hole in the nut to M4 and clearenced the hole in the tube and using a little M4 stud bent to 90 degrees was used to lock the rod in place.
I made a second holder tube and clamp to go on the end of the draw slider I spot welded it on at an angle that looked about right while I mocked up I then used the single carbon electrod rod in the stinger and using tig brazing rod added some extra strength to the join as I didn't want a very hot rod falling off if I caught it while working.
Step 4: Handle and Slider
The slot fitted nicely around the electrode clamp lever and with a little duct tape the diameters matched fairly well.
I used a couple of self tapping screws to hold the slider to the center web of the lock clamp and a M4 nut and another but of studding to make a screw lock so the slider could be locked open and keep the rods apart so I could put the torch down without it creating an arc accidently.
I left the frame loop of the lock mount on putting a couple of small bolt so it could be use to hang the torch if needed.
Step 5: Testing and Storage
After making some light and noise and then letting the torch cool down all the parts can easily be disassembled and put away for another day.
Step 6: Safety
Take it seriously or you will need someone to take you to hospital.
This torch also involves live current do not undertake if you are not competant.
You are responsible for your own saftey not me.
