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?
When did you purchase you’re powermax? I purchased mine in 2013, when I talked to hypertherm last week the tech guy (I don’t recall his name off the top) said ALL powermax45 have the cpc port on the back with a voltage divider (50:1) preinstalled. It’s usually hidden under a protective cap. I’ll take a picture when I get home tonight.
Thank you so much for posting this about the CPC port being under the protective cap. I have been looking into getting a Crossfire XR and already have the Powermax 45 (NOT XP). In looking at what all I would need to get up and running I was really stumped trying to find a CPC addon for the 45. Not really wanting to buy a new plasma cutter, your post was invaluable. Placed a deposit for an XR today.
