How to Set Up a Longevity Plasma Cutter

The Voice: Hey, Kevin. Is it Christmas?

Kevin Caron: Yep, Santa dressed up like a FedEx guy, dropped by the studio and delivered this wonderful piece of equipment!

This is Longevity Welding's new ForceCut 60i plasma cutter. Oooh, baby!

Check out this nice, clean design on the front of it. Here's the amp meter and power light. This is a warning light to show when your air pressure is low; your tip has gone bad, or if you've got a problem somewhere.

Here's your air pressure gauge to indicate your working pressure, and here's the regulator to adjust the air pressure coming from your air compressor; cutting amperage shows up here.

This is your post flow adjustment - post flow is how long the air runs after you let go of the trigger to cool the torch. If you're cutting with lots of amps, you might turn that up; if you're cutting with very low amps, you can turn that down. This is the manual setting or CNC.

This machine is big enough to run a pattern table, and they've even got the torch to go with it. You can go timed or constant on the air flow.

Here's the pressure regulator, and these are your hookups for your ground and for the torch.

Let me swing it around and I'll show you the back of it and how to hook up what's back there.

Of course, there's a power cable. It's a standard 220-volt single phase, so there are three wires in there: a black, a white, and a green - the standard hookup, whatever works in your shop.

The Longevity ForceCut 60i Plasma Cutter comes with this air connection hose that goes into the machine with a little press-in fitting. Also included are this little water separator and the little bracket for it with the screws.

The air hose slides in on this side, the hose from your air compressor clips on the other side. That's it. You hook this up and youíre ready for some serious metal cutting.

Over here are some extra cups, another slider (that helps keep your gun off your work as you're moving along so you don't ground out the nozzle), extra nozzles, some extra tips, and some extra fuses for the machine in case you ever need them.

It even comes with a CNC connector, which goes on the back of the machine and just screws in. Your computer hooks up, your torch hooks up, and off you go.
You can put this to work and go get a cup of coffee while it does all the cutting.

Let me show you how to hook the torches up. It's got a nice, long torch with a nice, long lead on it. You line it up with the little plastic boss at the top. That's it. The torch is ready.

Let me get the ground. Again, the notch goes at the top, into the hole, three-quarter twist, your ground is on.

So, now you've got your torch on, you've got your ground on, got power at the back. All I need to do is bring the air hose over, plug it into electric, ground out a piece of metal, and we're good to go.

Let's make some sparks. Grab your helmet and I'll show you how this thing works.

I've got power on, I've got air on, I've got my pressure set at 80 psi. Let's flip the magic button - 58 amps worth of cutting. The switch is right on the top. Push that button and you've got flame coming out the other end. Be careful!

The Voice: What's it rated to, Kev?

Kevin Caron: This machine, which costs $900, is rated to cut an inch and a quarter. My old Hypertherm, which cost $1500 several years ago, is only rated to one half-inch. (cutting)

Wow, this Longevity ForceCut 60i just cut a one-inch plate and 35 seconds; it's like a lightning bolt when you hold it!

This is the post flow; that air running. You can adjust that on the machine, but because I had it turned up so high, Iíll let this run for a second or two. Now it's off.

Not bad for one-inch steel plate, and I was speeding a little bit through there. It does a nice job; Iím impressed.

Longevity sent this metal cutting tool for me to look at and check out. They'd like for me to use it in some of my how-to videos on welding and metal working if I like it. They're not paying me for it; I'm doing this because I wanted to learn about the machines. I think I'll keep it.

To learn more about the Longevity ForceCut 601,

See you next time.
