The World’s Fastest Selling CNC Beam Coping Machine

The Ocean Liberator CNC Beam Coping Machine is the most affordable beam coper in the world, and is the result of a strong and productive collaboration with Peddinghaus, the number one manufacturer of structural steel fabricating machinery.

The Ocean Liberator will cut the copes in your steel beams faster than your layout man can even layout the copes. – Check out our CNC Beam Coping Time Study Videos.

In the same way that the Ocean Avenger CNC Beam Drill Line and the Ocean Clipper CNC Angle Line brought affordable automation of beams and angles to the small-to-medium fabricator, the Ocean Liberator similarly brings automated beam coping into shops that otherwise could never have considered it.

The Ocean Liberator is an amazingly economical 5-axis CNC robotic oxy-fuel cutting beam coper that will enable you to make any type of cut on beams, channels, angels, plates, and rectangular tubes.

Literally anything that you can draw, can be cut by this superbly versatile profile cutting machine. Not only does it cope, but it cuts to length too!

This single torch CNC beam coper removes the need for manually laying out your copes, and ensures that copes are done neatly and accurately, direct from your CNC detail drawings.

Capability Design

  • The Ocean Liberator features a rigid heavy duty frame welded frame that easily mates to a variety of automatic or manual in-feed and out-feed conveyors (typical configuration uses 45ft of in-feed and 45ft of out-feed conveyor).
  • This solid frame provides the rigid platform from which the articulated 5-axis torch is driven, ensuring accurate and repeatable copes and cuts in a variety of profiles.
  • The Liberator uses a 5-axis fully articulated cutting torch, which allows it to cut from any angle on any surface, easily allowing bevel cuts in both the web and the flanges, something that more expensive multi-head machines are unable to do.
  • The beam coper is equipped with a heavy-duty automatic igniter for simple automatic ignition.
  • A handheld remote pendant allows fine-tuning of the cutting gap and travel speed, and provides the operator freedom of movement during cutting.
  • This supremely versatile machine allows coping and cutting of beams, channel, angle, plate, tube.
  • The Liberator cuts steel at speeds of up to 30 inches per minute depending on material thickness and hardness, type of gas, flame adjustments, and other factors, and has a fast positioning speed of up to 400 inches per minute.
  • Simple and easy to operate.
  • No computer experience required.
  • Fastest Return on Investment of all Ocean products.
  • Immediate payback on a low investment through attractive finance options

The Ocean LIBERATOR CNC Beam Coper is designed specifically for fabricators and general job shops that need to cope or notch steel profiles of all types. Consider the following questions and determine if this machine fits your needs:

  • Do you regularly notch or cope steel beams, angles, tubes, or channel?
  • Do you layout these copes by hand, either manually measuring them out or do you use a template to trace out the more repetitive copes?
  • Do you do a lot of skid, platform or trailer work where all the cross members need to be coped prior to welding to the frame rails?
  • Do you fabricate multi-story buildings where the floor beams need to be coped to ensure a level floor?
  • Do you notch out the top and bottom of channel for stair stringers and platform details?
  • Do you regularly use a tape measure, framing square, and chalk to layout the these copes and cut outs?
  • Are you looking for a faster, cheaper way to do it?
  • Are you limited by the amount of capital that you can invest in a beam coping line?
  • Is your current method of beam coping and beam fabricating too costly to compete with the bigger fabricating shops and do you lose out on those profitable big jobs?
  • Do you have to turn away big jobs because you cannot physically process the larger and heavier profiles?
  • Do the larger General Contractors skip your company when sending out the bids because you cannot process a large structural job or beam job fast enough?
  • Do you struggle to find good quality fabricating labor when you land a large job, and do you have use valuable skilled labor to train your new recruits?
  • If your layout man skips work for a day or two, does that affect your ability to process and fabricate beams?
  • Are you struggling to land steel fabricating jobs in your market?
  • Do you feel your competitors are throwing out insanely low numbers to land the work?
  • Are you finding that you are struggling to make any money on the jobs you land – those jobs that you bid low enough to get leave, no you profit at all?
  • Do you want to make more PROFIT?

If you answered YES to any of the questions above you are a prime candidate for the outstanding Ocean LIBERATOR Beam Coping Machine, built by Peddinghaus USA.

Here are some of the more commonly asked questions


What skills does my operator need to run this machine?

We always recommend that your Ocean LIBERATOR CNC Beam Coping Machine operator is someone who really knows how to cut with oxy-fuel. We can train almost any operator very quickly on the software side of the machine, but the skill and experience of cutting with gas is something that is built up over years of cutting by hand.

How much computer knowledge does the operator need to run this machine?

The Ocean LIBERATOR CNC Beam Coper is very simple to operate and most of our LIBERATOR operators were the men doing layout on the floor. No prior computer knowledge is necessary, and full training is provided at the time of the installation.

How difficult is it to program the machine?

Programming of the LIBERATOR is very simple even when done manually. The machine programming software is Peddimat and most operators can learn how to program most parts in less than an hour. Of course practice makes perfect. However the best way to program the machine is to import parts directly from a CAD drawing preferably done in some 3-D modeling software such as Tekla Structures, SDS/2, ProSteel 3D, StruMis etc. These files import directly into the machine. In some cases the operator might need to edit the part program to create a lead out to ensure smooth cutting and then he merely selects the part to be processed and hits the Cycle Start button.

How much training is included with the installation of the Ocean Liberator?

Since the operator’s skills with cutting with gas are so important, we always prefer that your operator/s attend our LIBERATOR certification program at Peddinghaus’ in-house training center. This one week training course is provided free of charge when you purchase your LIBERATOR. Your operators will be fully trained and certified prior to the arrival of your new machine at your site.

At the time of machine installation our factory trained service tech will spend approximately 5 days on site, installing your machine, calibrating it and re-training your operators. This will provide more than enough hands on operation, as well as maintenance, troubleshooting and diagnostic training.

*NOTE: Coping machines, more than any other CNC machine in structural steel shops, depend on well-trained operators. It is your responsibility to ensure that all Ocean Liberator operators have been trained in our Operator Certification Program.

Can this machine be installed outside?

While we always prefer that the machine is installed indoors, we do in fact have several LIBERATOR beam coper installations outside. However suitable weather protection must be provided to the control panel and the machine itself. Please feel free to contact us to see photos from many of our outside installations.

What is the relationship between Peddinghaus and Ocean Machinery?

Peddinghaus builds machines specifically for Ocean Machinery to meet our demanding specifications. Ocean Machinery specifically targets the small to medium fabricator whereas Peddinghaus targets the larger fabricators. Peddinghaus has been building machines for Ocean Machinery for more than 10 years, and Ocean Machinery is Peddinghaus largest customer worldwide.

If the machine breaks where do I get service?

The Ocean LIBERATOR is built exclusively for Ocean Machinery by Peddinghaus. Peddinghaus handles the installation, warranty and service work on the Ocean LIBERATOR. And while Peddinghaus is the service provider, Ocean Machinery is always there to get involved should the need arise. Please see the SUPPORT tab for more answers relating to service.

What is the maintenance cost on this CNC beam coping machine?

The LIBERATOR beam coping machine is a very simple machine with very few moving parts, making maintenance and parts exceptionally affordable. The Ocean LIBERATOR was designed specifically to be used throughout the world and thus uses only components from major manufacturers, most of which can be sourced in the local market. Peddinghaus keeps all parts on hand for next day delivery in the USA. In most of our overseas countries we offer local service and support.

Why use Oxy-Fuel and not Plasma?

Plasma heads are very popular for cutting steel, due to the high quality and speed of the cuts. However, due to the size of the plasma cutting head it is not possible to get the head close enough to the flange, and many styles of copes typically required in beams are just not possible with plasma heads.

Another drawback is that when cutting thicker areas of a part, even on light wide-flange beams, for instance the radius at the intersection of the web and the flange, it is typical for the flame to blow back, and this can and cause damage to the plasma head.

Because the Ocean Liberator CNC Beam Coping Machine utilizes oxy-fuel, thickness of material is totally irrelevant and any material up to 6″ can be coped.

And of course the most important reason is cost. Cutting steel with plasma produces highly carcinogenic dust that MUST be captured in a dust extraction filtering system. This as well as the cost to completely enclose the machine to evacuate the dust raises the price to far beyond what our typical fabricator is prepared to pay for a beam coping solution.


What are the consumable costs for the Ocean LIBERATOR CNC Beam Coping Machine?

The cutting head for the Ocean Liberator CNC Beam Coping Machine is a simple and inexpensive oxy-fuel head, and utilizes oxygen and any fuel of your choice, including propane, acetylene, propylene, or natural gas. These gases are very inexpensive and freely available from your welding supplier, and welders familiar with hand torch cutting will be able to set up the flow rates of the Oxy-Fuel just as they are used to doing.

How much does the torch tip cost for the Ocean LIBERATOR?

The Ocean Liberator uses a specially designed torch nozzle that will typically last about 3 – 6 months depending on how hot you run the machine. Because of the break-away head that deflects the torch nozzle, the torch nozzle is almost impossible to bend.
However, the nozzles eventually get worn out due to the heat of the gases passing through the nozzle. Replacement torch tips are around $75 per tip.

What is the difference between a single torch and 3-torch coping machine?

A single torch CNC beam coping machine is a 5-axis machine that uses only one torch to do all the coping. When coping a beam, the single torch will start cutting at the web and then move on to the flanges. It moves from the web to each flange in sequence. The 5-axis torch is able to move in an almost infinite number of directions and positions, allowing the most complex of copes. The 5-axis torch and will accomplish double miter/bevel cuts on both flange and web – something that multi-torch systems are unable to do.

Multiple torch or triple torch CNC beam coping machines typically have three torches, and each torch is dedicated to a flange or web. Even though there is less positioning time with the triple torch machine than there is with the single torch machine, the single torch machine can do a lot more cuts than the EXISTING triple torch machines due to the versatility of the 5-axis movement of the cutting head. In addition, most triple torch machines cost 3-4 times more than our single torch CNC beam coping machine.

And most importantly, several large fabricators have upgraded from a 3-torch machine to an Ocean LIBERATOR. That will tell you everything!


If my machine operator leaves my employment, how do I get more training?

Peddinghaus offers regular training courses on all Peddinghaus and Ocean equipment at their facility in Bradley Illinois. These courses are suitable for new operators and for refreshing existing operators. Employees that pass through this facility return to your shop highly trained, motivated and eager to improve your productivity. Please call for details and pricing.

What warranty is supplied with the Ocean LIBERATOR Beam Coping Machine?

The LIBERATOR is supplied with a 12 months parts and labor on-site warranty. If your Ocean Liberator Beam Coping Machine breaks down during the warranty period, factory service technicians will get your machine up and producing in the shortest amount of time possible, at no cost to you.

Outside the warranty period, on-site technical support is available at standard charge out rates.


How safe is the Ocean LIBERATOR Beam Coping Machine?

Ocean Machinery and Peddinghaus are dedicated to proving affordable, reliable CNC solutions that not only work, but also provide safe operation for your employees. The Ocean Liberator is built to the highest safety standards using state of the art components.

Using a CNC beam coping machine is actually safer than using a handheld torch. The operator is able to operate the machine remotely and this moves the operator further removed from the cutting flame.

The Ocean Liberator beam coping machine is equipped with extended rigid and durable torch tips that enable accurate positioning inside flanges. In addition, the closed loop system allows the torch head to break away in the event that the torch head contacts an unexpected obstruction, such as slag build-up.

This safety mechanism ensures long tip and head life as well as significantly increasing up time to avoid costly torch tip changeovers and repairs.

All pressure and flow gauges for all gases are easily accessible and can be quickly adjustable.


Programming the Ocean LIBERATOR CNC Beam Coping Machine is very simple and intuitive even for operators with no CNC or computer experience.

We have installed more than a thousand CNC beam lines and angle lines throughout the world and we have found that the average operator, who has never before programmed a machine before, can become efficient on the machine in less than 1/2 day.

Ocean LIBERATOR CNC Beam Coping Machines can be programmed in one of two ways:

1. At the machine, manually enter the clip angle data including the angle size, length, size and position of slots and holes.

2. Directly Import of the data to the CNC beam line directly from your CNC steel detailing files.

cnc beam coping machine for structural steel



The Ocean LIBERATOR can be programmed manually at the machine or in the office using the supplied Peddimat software. This software comes included with the LIBERATOR and can be installed on as many PCs in your office as you choose — this unlimited license is included with the purchase of your machine. It is the same software that is found on the machine itself and is the same software used on the Ocean LIBERATOR and all Peddinghaus CNC fabricating machinery.

Peddimat is incredibly simple and intuitive, and takes less than an hour to learn, even if you have never worked on a computer in your life.

We always train your operator how to run the machine using Peddimat as you are often going to have the situation where a customer arrives with a couple of pieces of steel that need holes or layout marks and you want to be able to produce them quickly without bothering your detailing staff who might be busy on a larger job.



It is obviously preferable to import files directly from your steel detailing software because it eliminates an unnecessary step and also eliminates possible incorrect data capture. There are two separate and distinct camps in this respect:

1. 3-D Modeling Camp

Software that falls in this camp includes X-Steel, SDS/2, Tekla Structures, StruCAD, DetailCAD, BOCAD, SteelCAD, ProSteel 3-D etc. All these 3-D modeling programs export the DSTV file that is seamlessly imported into the LIBERATOR.

Your detailer will then supply you a DWG / PLT / PDF file that you will use to print or plot your drawings. He will also supply you with the NC or NC1 files that you will import directly into your machine. The DSTV-Import function is standard on the Ocean LIBERATOR.

2. AutoCAD Camp

AutoCAD is and architectural software and works well for exporting flat 2-D pieces to plate processing machines. Where it falls short is in its ability to export files for 3-D shapes like beams, channel, angles etc. AutoCAD exports both DWG files and DXF files which are perfect for plates.

The Ocean LIBERATOR can import DXF files and can use them to process 3-D shapes as long as the steel is detailed according to specific rules. Some of these rules might be different to the way you are detailing at the moment and might require some adjustment. This process is not nearly as seamless as the 3-D modeling software solutions above.

Once you have created a DXF IMPORT COMPLIANT AutoCAD file, you then import it via the DXF-Import Utility (optional purchase)

Customer Feedback

  • “.. in the two and a half years we have had an Ocean Liberator, the efficiency and quality of the preparation procedures for our product has been drastically increased. Coping and weld prep of the past was very time consuming. Manually laying out and burning left a lot to be desired. With the Liberator, the burns are much cleaner, reducing grind time dramatically. The Liberator is a compact machine that delivers big results. All in all, Ocean has provided an opportunity to save time and energy, which equals out to saving money and our customers get a quality product.”

    Dan Cina - South Central Steel

  • “..the time the Liberator saves us for cutting the beam itself, you add on top of that the time it saves us fitting 2 pieces together so accurately that no trimming or additional work is required. In regard to welding, we are not filling gaps anymore. We save time in both the fitting and welding of the structure. Beyond that the amount of grey hair I have saved from having the Liberator do my work, as far as I am concerned is PRICELESS!”
