 Left to right : Pulse1, Pulse2 and Voltage adjustment
This took me way longer than expected and I was hoping to have it done by the end of this weekend. The aluminum brackets that the pcb's are on took me most of Saturday to make. I broke two brackets before getting it right and then had a hard time mounting the pcb without making a short. I finally cut all my hard work off and put a piece of wood between the the two cut offs. Bending, drilling and fitting the copper bars took up all of today.
I did however test the dual pulse before tackling this job and I am very pleased with the results. It works better than expected and you can use any one of the two pulses by turning anyone off or use both. At this moment you get two bleeps when you use the dual pulse and one bleep when you use one pulse, it is very fast though and sounds more like a long and a short bleep. It's things like this that needs a little attention.
I will try and have it finished by next weekend and hopefully get it on youtube.


  1. Nicely packed Fritz. I asked around for welder cases but none were available. I'll keep an eye out for a smoked welder. Thanks for the update. Looking forward to the video. -Mike

  2. are you you using one cap for both pulses?
    what is your time range for each pulse and between pulses?

  3. Yes, one cap and the the processor works out the time between the pulses.
