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?
Not sure if you got any answers…
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.
Here is one photo of the back of my machine as factory, and the second is with the cap removed.
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.
