Powermax 85...burning smell

Post by jbc28 » Sat Jan 27, 2018 2:18 pm

I have a 85 that I bought new back in 2014. It gets used about 10 hrs a week on average. Lately I have noticed when the cooling fan cuts on it has a faint burning smell. If you have ever smelled electronics that "has let the smoke out" this is what it reminds me of. So far it is operating flawlessly, no codes, or any other thing that would indicate a problem. Has anyone else noticed this with a Hypermax? I wondering if there is something I could check before a bigger problem develops. Thanks.

In my case that happened once when I needed to blow the dust and lint out of the cooling flow area.. Maybe time to remove the panels and give er a good cleaning..

I would remove the cover from your Hypertherm (not Hypermax) Powermax85 and blow it out with an air hose. You may find something inside (bugs, dust, debris) that is making the smell. If an electronic point is burning you will likely see it immediately with a good once over inspection. Disconnect power before removing the cover...there are voltages up to 800 volts on the main Power board. Jim Colt Hypertherm

Thanks for the info. Yes Hypertherm...not max. Autocorrect kicked in there. I will pull the cover and check it out. I do have a 45xp that can be used as a back up, but I hope it just needs a cleaning.

I know this has been a while but I wanted to give an update. No problems with the cutter. I had a loose connection in the plug that caused it to heat up and melt the plastic.
