Exair cabinet cooler

[Pat4rd]

Last week I purchased a Quincy 60 5hp compressor.. man what a difference. On Saturday I decided to Put it to the test. It easily supplied enough air for my equipment. I did have a detailed cut I needed to do out of 3/16. Around 11 mins in my duty cycle was reached on my 45xp and it shut down. I don't blame it- it was a really hot day and my shop does not have ac. Looking for a fix to that problem I came across a product called exair cabinet coolers. I have my plasma in a cabinet along with my computer tower. They share a 4.5" filtered cooling fan. I was thinking about mounting one of these exair coolers behind my 45xp to keep it a little cooler. Is that a good alternative? I have seen code snippets to pause the table and let my plasma cool down but I have not figured out how to do that.. im going to start researching it. I do use sheetcam and Mach 3. Thanks for any info! The pic of my cabinet was taken awhile back, it does have front doors on it now

I have seen the stop command is (M00) do I just do a edit g-code and throw that M00 in before it fires the torch?

Looks great; Not sure if the tower and plasma play well that close together?

So far they're playing nice.. I have spaced them farther apart but I haven't seen any signs of glitching. Knock on wood

Hey Pat4rd,
I see you are running Mach3. If you want to pause your cut to allow your 45XP to cool just hit the Feed Hold button on the Mach3 screen when it's between cuts and the machine will pause. Once cooled, hit Run and the machine will continue your cut.

that sounds like a good solution to my problem! thanks rick. i did see where a guy ran a window ac to his cabinet to keep components cool. lots of great ideas on here but for right now i will probably do the feed hold.

I have never in 6 years had my PM45 cut out on duty cycle!!!! But I don't have it enclosed in a cabinet. It sits on a shelf at the end of the plasma table.
Why create a problem by enclosing it? And then look for a solution to that problem? JMHO

I strongly recommend that you take the plasma out of the cabinet. In free air you will not reach duty cycle cutting 3/16". Perhaps on 1/2" on a day that is 104 F or higher you could as the arc voltage is much higher (amps x volts = watts.....more wattage output = higher heat developed). Hypertherm systems are designed to operate in dirty shop conditions, there is a clean side, dirty side inside the power supply and it depends on its microprocessor controlled cooling fan for cooling efficiency....a cabinet will not allow that technology to work.

The cabinet cooler is for computer electronics and their typical low wattage (maybe 700 watts) heat production, not a 6500 watt heat load like the Powermax45 XP!

Thanks for the guidance guys. At first it seemed like it would keep everything cleaner, and more organized. Now I see the problems it's created haha. I'll build a little stand off to the side for it tonight
