I wanted to put this out there for anyone else that might be experiencing a similar issue. I recently purchased a voltage divider and began the process of wiring it in last night. The instructions were very clear and after reading them no less than a dozen times I triple checked everything and began attempting to dial in the adjustable voltage. The instructions told me to check my voltage from the plasma cutter by dry firing the torch. I determined I was in the range of 2.5v. Which is exactly what I was informed raw voltage should be via the instructions. Next I hooked the Div V leads to the arc droid. The next step was to dry fire the torch and adjust until the TC read approximately 70. This is where my problems began. I was reading a static TC 8. Firing the torch would not increase the TC numbers. I went back to the instructions and after nearly memorizing them, I began trouble shooting. I ensured my wiring was correct, it was. I ensured my voltage was within range, it was. I made some test cuts and found the THC was not functioning due to my plasma torch plowing into the work piece. After some minor and admittedly major adjustments on the voltage divider (never exceeding safe voltage of 3v) I was no closer to getting the TC readout to change. While chewing on the problem, I placed my hand on the AcrDroid console, I noticed the TC number now dropped to zero. While this was interesting, I didn’t connect the dots immediately. Fast forward to this morning. I removed the console from it’s bracket on my table and found once again, TC dropped to zero. I test fired the torch and found I could consistently reach a 50ish on the TC readout (70 after minor adjustments). I placed the console back into the bracket, watched TC raise to 8, attempted to test fire and found the previous issued reoccurring. My table is a custom build specifically for the ArcDroid (pictures soon). There is continuity between the console bracket and the table. The metal housing of the console touching the bracket was generating the odd behavior with the THC. So, long story short, isolate the console during use. I’ve place some felt cloth in the bracket and haven’t had an issue since. Hopefully this information helps somebody out there.
