Hypertherm Powermax 45 THC Installation - Help Needed

Hi Everyone,

I have an older Powermax 45 model, not the XP. There is no CPC port, so according to the THC guide Langmuir has on their website I need to connect to my plasma cutter’s raw voltage (step 4). Is this correct?

I was able to find a post where an individual was able to wire directly to a Powermax 45 XP circuit board. However, it seemed like this circuit board was a different configuration than my older Powermax 45 model.

Has anyone installed a THC on an older Powermax 45 model that would mind sharing some notes?
