Howdy,

I just got my hands on a 10' x 110ton accurpress press brake but I don't have any documentation for it. Anyone out there got a legible bend chart for Accurpress? I'm trying to figure out...

It's got to be able to cut smaller than 42" as well...probably down to 8 or 12 inch pipe. Another thing I want it to do is bevel cuts...probably at 45 degrees...basically to create a gap for welding...

It doesn't have to go very fast...probably no more than 40 inches per minute of surface travel....but the pipes are big. 20' thru 40' sections of 42" OD pipe of 1/2" thickness...might way a couple...

I'm kludging together a plasma torch, some rollers and a steel frame to make a machine that can cut 42" OD (or smaller) steel pipe. The machine will not only cut but it will have the potential to...

What is the proper relationship between the grounding of a CNC machine, the work table and the plasma power supply itself?

I'm putting together a CNC plasma machine, and have worked on others in...

Okay...been a while since I was last here (Welcome back, jgramlich, there have been 146,333 posts and 20,236 threads since your last visit at 11:24 PM, 12-10-2010). I need some help reinventing the...

Yeah, I'll try to do that in the next few days...we're busy as all get out here right now.

Howdy,

I've got an HPR 260, Hypertherm plasma unit with what I *believe* is a Hypertherm torch lifter. There's a 2" wide plasticized/canvas band that seals the torch lifter body from debris. ...

Oh, and I should have been more specific about the location of the table. Our shed is large, very swiss cheese and we store a couple of hundred tons of steel in there, so when it gets cold at night,...

On my table, the breakaway system uses air pressure to hold the torch head in place. It's not very high...I think 40psi. Air pressure pushes a plate that the torch head is connected to against a...

Something else you can try...disengage your motors and see how easily your torch head moves along the rails with you just pushing it along. I know I've had some cut quality issues with seized...

Thanks for the input folks. :-) Looks like the freezing season is gone for this year.

What seemed to work in the end...I stopped shutting off my line-dryer at night. Not sure if this actually...

Hmmm...interesting idea. I do have something I could rig up for a heat exchanger just before it goes into the plasma unit...would be pretty easy too. Thanks!

I've seen this happen on my own table, but the problem has always been in the .dxf files I was using to program the cuts.

I'd say your problem smells like software, if all you have to do is...

First: Yes, I want to move my plasma table indoors, but that option is not currently possible.

I've got an Hypertherm HPR260 manual gas console connected to a Controlled Automation Promax burn...

Hmmm...what thickness of plate are you cutting? Mine is only visibly noticeable when cutting 1" or thicker (and I've got a 260A Hypertherm unit)...and that's really only when it's doing holes and...

Howdy,

One cheap/dirty way I use to determine if my THC is working is to lightly put my hand on the torch cables while it's firing. With my THC, though I cannot see the tiny adjustments of the...

Weird...I'll see if I can find something else.

I think we got ours here, but I'll doublecheck:

Darkhorse,

That PlasmaQuench you can just dump in your back yard. It's the same stuff they use to dye the Chicago River green during St. Patrick's Day. Hell, you could drink it if you...

I'd post at both. Won't hurt anything.

First, you should consider starting a new thread on this one.

If you do, let us know what plasma unit you want to use and take a look at a few of the "torch height control" posts in this...

Computer horsepower is probably not very important. Anything with half a gig of RAM and built within the last 2 or 3 years should be enough. Just make sure you don't get Vista. :-)

At the very...

I don't think there's any bypassing that "feature". :-)

There has to be a path to ground for the torch to fire. It cannot fire over empty space...unless someone out there knows of a plasma that...

Yeah, I'd just check for any needed purge(pre) and cooling(post) times and set your relays accordingly. If you don't find any specific times, 30 seconds on each end should be well more than enough.

You *might* even be able to use a flash drive with Windows 98...but its been so long I cannot remember for sure...and we do have a DOS machine running our drill that we use flash drives to load...so...

Does the machine have a USB port? How old is the computer and operating system? Also, how does the computer attach to your plasma table? For $325 you can nearly buy a whole new computer...
...

One thing I got out of that video I posted above is the shape/direction of the arc beneath the plate. When the torch is cutting near the edge of a plate grab a piece of dark glass/faceshield and...

Ah, I know what you're talking about but I don't think I've seen that particular post. I'm interested in that as well. :-)

I did find a pretty cool little video over at Hypertherm's web site not...

I'm going to toss some even more geeky stuff out here. My burn table manufacturer doesn't produce custom APIs to allow me to write my own code against their software so...

Anyone out there...
