Havent been on here in a while, but i figured this is the best source of info. ive tried searching on here and the rest of the net as well and cant seem to find anything. I am looking into buying a thermal dynamics custmaster 82. I just installed a 125 amp subpanel in my garage, and im now waiting on my electrician to come tie everything together. The Plasma cutter comes from the factory with a 6 ft length of wire, which i am assuming is designed to be hardwired into some sort of junction box. Seeing as it draws 80 amps at full load, are there any plug/outlet combinations that would work with this? If it has to be hardwired its not really a big deal, it would just be nice to move it around or make up a short extension cord to use it outside. thanks in advance for any help.

`I use a standard 30 amp twist lock for my miller hypertherm 675. I switched all my welders to this type of plug.
I don't think you need a plug that can carry 80 amps.
They don't put a plug on welders or plazma cutters, because they figure you are going to change it to what you want anyways. I know I did.
I'm sure the pro's will chime in soon.

You can use 6-50 hardware for it. What is the listed wire size? Might post the duty cycle of it too. Or a link to the electric service guide.

If you expect to use the plasma cutter anywhere near full amp draw (72 amps according to the specs), you'll have to hardwire it. There is no 220v single phase plug/receptacle rated higher than 50 amps. They do make 3 phase connectors rated for higher amps, but they are wicked expensive.

I have a miller 375 and recently ran a 30amp twistlock outlet for it.
But wow, that TD you got pulls 80amps or close to it. That's a hell of a cutter, but I see it says it cuts up to 1.5" that thing has some balls.
I see sometimes machines, motors, and welder recommended wire sizes, length, breaker rating vary from the typical 80% or x1.25 guideline for breaker rating due to startup load, duty cycle, etc. But if this cutter is calling for 72amps for input power, should it be on a 90 or 100amp breaker? 72x1.25=90

This a current x time factor, I am not familiar with all the TD models but this is not a big deal, no reason to lose sleep. Some machines such as 200 synch allow 8 wire with breaker at 100A, there should be electric service guide in the manual. This will list the wire size, just in general suspect a if single circuit in pipe of with cable. Personally would stick a 60 on it and see how it went, only screaming wide open will this matter, near continuous cutting at max in a fab shop. The 50A plugs will be fine especially in home/hobby environment.
