    Powermax 45 won’t cut through metal

    My PM45 won’t cut through 16 gauge steel at regular speeds. It fires, but cuts half way through and blows slag all over the place. You just get an 1/8” wide melted grove in the metal. It’s at the...

    The X axis on my plasma cutter has stopped working intermittently. I have a 4X8 plasma table. X axis is along the 4 foot gantry, Y runs the 8 foot length of the table. It started developing a symptom...

    Re: Unwrap a curve?

    Thank you. That totally did exactly what I wanted.

    And thanks to everyone who responded. I don't think I made it exactly clear that I'm rotating the pipe (x axis) under the torch and the torch...

    Unwrap a curve?

    I built a tube cutter attachment out of the headstock of 9x20 lathe for my CNC plasma cutter. I can cope pipe with it all day long. I know there's a coping calculator on the internet and I've used it...

    I'm only guessing here, but I suspect the thinking is it could cause the bearings to arc as they turn, but I also suspect that would be much more of an issue with rotary welding than plasma cutting....

    The ground was on the table. And the pipe is resting on a metal cradle I made for it to ride on, which is bolted to the table. I powder coated the individual parts of the lathe headstock and...

    I used the gears because it just happened to mesh with the gear that was already on my stepper. It was like providence. :-)

    Thank you. I think that's where I eventually ended up. I jogged the motor one complete rotation and noted that it came out to something like 5.23 inches. I took the steps per unit, multiplied it by...

    Tube Coping motor setup

    So I was cleaning the shop and wondering what to do with this 9x20 lathe I picked up for spare parts. And it occurred to me, that's practically all the parts a guy would need to cut tubing. The gears...

    Hypertherm vs Thermal Dynamics

    I used a Cutmaster A40 for about 3 years. I'm glad I got rid of it. I built a new machine and put a Powermax 45 on it. It's worth its weight in saved consumables.

    I'm getting anywhere from 5 to...

    I understand that it shouldn't rise, but it often does anyway. 18 gauge gets springy, warped, and all kinds of fun stuff. So when I say "rise" it's not supposed to, but it does anyway. It will do a...

    Which Plasma Cutter Would You Pick?

    I usually cut a lot of 18 gauge cold roll. I also cut a lot of 16 and 14 gauge hot rolled. I sometimes cut 12 and 10 gauge hot roll. Every once in awhile I'll cut 1/4" sheet, or cut holes in 1/4...
