Hello all, I am wondering if anyone is using a Technogon height control unit for their Dynatorch plasma tables? I see on their website that they offer Technogon boxes for their systems. I have one of these older models: LD2A is the number and I am having problems with it. It has a white housing with a clear side so I can see all the internals. There is an auto/manual button, up/down, and an on/off button on it that is all. ANY HELP would be appreciated I am having a hard time finding any info on this and I currently have no up/down movement on my torch. Thanks.
