How old is your Torchmate system? Our AVHC System complete costs about $2400 new, and works with your existing system. I checked with Parts and they do have an Older Style AVHC system on the shelf that could be more than %15 off that price. The reason I ask the age of the machine is because the older TM systems won't be able to take full advantage of the OK to Move signal from your plasma cutter that our AVHC system takes advantage of, without an upgrade to the latest chip and software. However our slightly older system that is delay based still is a fully functional AVHC system that would work great on an older TM machine.
If you are using version 2.20 or newer you would be best off with the new system but would still work with the slightly older system.
Any questions on this you should give Brook in our Parts department a call, and she can help you out with any other pricing questions!
