Hey guys. A while back I got myself a new RBA and it is the type that you need to attach pieces of non resistive wire to the ends of the kanthal wire. I have been doing the twisting together method which works but seems to loosen up over a short time. Read up on how ecig guys made the weld. Seems there are some battery tab welders which will do the job. Seemed a lot of work to make a spark.
My theory was that the only thing I intend to use it for is attaching kanthal to wire rap type wire so a million options was not needed.
Found that 35 volts and 2200 microfarad seemed close for the procedure.
Got together what I could find around the shop and came up with the following.
-DC/DC converter capable of 4-55 volts out 5 amp peak and 3 amp running. More importantly over current protection and self resetting.
-Push non-latch button switch
-2200 cap 63 volt max
-A 5.5X2.1mm DC plug for supplying power
-A box to hold it. I found a LED variable power box left over from a different project.
-Connectors for the output. Found some banana type plugs and one with a BNC adapter.
So this is the parts before wired:
A very tight fit. Like it that way.....
And with the connectors installed.
Wired and ready to close er up.
Looking good. The hole is to adjust voltage if need be. 36 volts works fine for my needs.
It took a few times to get it down but works quite well. Just put the kanthal (which is a twisted pair of 32 AWG in this case) in the ground side and alligator clipped the non-resistive, aligned, pushed button for a couple seconds and bring the tips together.
The circuit is quite simple. The output of the converter goes to the push switch and when pressed it charges the cap which is on the output leads. The leads are safe until you press the button. The only safety feature here is common sense, always short out the output when not using.
Have gotten good results.
Nice small footprint. Specially once the output is detached.
And I found if more power is needed, the voltage can go up or increase the capacitance externally. This way you can join larger things.
Anyway, thought I'd share. Now don't blame me when you zap yourself...
