Preparing tube and pipe for fabrication can involve measuring, marking, cutting to length, coping an intersection, making holes and grinding the joint to fit. A CNC plasma tube-cutting system brings many of those operations into one programmed process.
For shops producing handrails, frames, structural connections and other assemblies, that can mean less repeated layout, more consistent parts and a faster transition from raw stock to assembly.
Ercolina’s ErcoCut EC220PHT-75M and EC245P plasma systems combine material positioning, plasma cutting and software for preparing the geometry. The EC245L is a laser machine; this guide focuses on plasma.
What can a CNC plasma tube cutter do?
With the appropriate configuration and setup, CNC plasma can produce straight cutoffs, miters, saddles, copes, tube notches, slots, hole patterns and profile intersections. Beveled edges require the appropriate equipment.
These operations can be useful on round tube and pipe, square and rectangular sections, and suitable open profiles.
Plasma cuts electrically conductive metals. Ercolina lists steel, stainless steel, aluminum, brass and copper. Suitability depends on material, thickness, plasma source, consumables and required edge quality. A machine that can hold a section is not automatically qualified to cut every wall thickness or feature within it.
Reduce repeated manual layout
Manual layout requires operators to transfer measurements, wrap templates around pipe, establish feature orientations and check marks before cutting.
Programming can reduce those repeated steps, particularly on parts with several holes, changing feature orientations, a cope at each end or repeating slots and notches.
A proven program provides a consistent starting point for repeat orders. Stock, setup and first-part inspection still need checking, but the operator does not have to reconstruct every feature by hand.
Included software: create the cut or import geometry
Ercolina describes included software that allows the operator to create the desired cut and analyze the torch path before cutting. The EC245P brochure also describes part design, data entry, nesting, file transfer and remote diagnostic capabilities.
Create suitable geometry within the software
For supported operations, the operator can enter dimensions and define features without preparing a paper template. This can be useful when a customer supplies dimensions or a drawing rather than a production-ready digital model.
Have the supplier demonstrate the built-in functions on your parts. Included cutting software should not automatically be described as a replacement for a complete mechanical CAD package.
Import a compatible CAD file
The published EC220 information identifies IGES and DXF import. The EC245P brochure additionally lists STEP. The literature references compatible exports from CAD systems such as SolidWorks, Tekla, SDS2, AutoCAD and Pro/Engineer.
Import can reduce re-entry, but compatibility depends on more than the filename extension. Have the supplier demonstrate your actual file, correct units and scale, recognition of the intended geometry, the stock section and the resulting toolpath.
The practical promise is importing supported, compatible CAD geometry—not opening any file and cutting it without checking. Confirm software version, import modules, licenses, workstation arrangements and any file cleanup required.
Review the torch path before cutting stock
Preview helps the operator review orientation, feature placement, unexpected geometry, cut sequence and material usage before committing stock.
Nesting functions can help arrange parts on available material, subject to gripping requirements, end remnants, part separation and the working envelope.
Simulation is a planning aid, not a guarantee. Accurate stock information, the correct machine configuration and safe first-part proving remain necessary.
Controlled positioning for consistent features
Ercolina publishes servo-controlled motion, brushless rotational drives with absolute encoders, low-backlash planetary gearboxes and a low-backlash helical rack-and-pinion carriage drive.
For the buyer, these features support controlled positioning of the stock relative to the torch. That can help repeat hole locations, end profiles and the relationship between features more consistently than repeated hand layout.
Positioning capability is not a guarantee of finished-cut tolerance. Torch height, cutting parameters, consumable condition, source performance and material condition also affect the result. Maximum axis-travel speed is not the cutting speed for every material.
Support long stock correctly
Ercolina describes automatic material supports coordinated with the programmed part and front-gate arrangement. These can simplify leveling and support as sections change.
Buyers still need to review stock straightness, weight per foot, handling, support spacing and the behavior of parts after separation.
The EC220 literature identifies manual front and rear chucks. Automatic CNC cutting does not mean fully automatic loading, gripping and unloading.
EC220PHT-75M: published features to evaluate
- Hypertherm Powermax85 plasma source listed as standard.
- Round-section capacity from ¾ inch to 8⅝ inches.
- Square-section capacity up to 6 inches.
- Rectangular-section capacity up to 8 × 2 inches.
- Maximum standard material length of approximately 24½ feet.
- Automatic material supports and manual front and rear chucks.
- Servo-controlled positioning.
These are reference specifications; confirm material, weight, wall thickness and required features. The EC220 data sheet lists automatic beveling to 45 degrees left and right, while its webpage lists beveling among optional functions. Resolve the supplied head and beveling configuration explicitly in the quotation.
EC245P: evaluate the complete configuration
The EC245P brochure describes design and cutting software, CAD import, nesting, touchscreen control, servo-driven positioning, supports and modular table arrangements.
Beveling, drilling, threading and automatic loading are listed among optional capabilities. Drilling and threading are separate processes, not operations performed by the plasma arc. They require the appropriate equipment.
Do not transfer capacities or accessory claims between the EC220, EC245P and EC245L laser machine. Compare the exact quoted configurations.
Better fit-up can reduce downstream work
A repeatable saddle, cope or notch can make assembly more predictable. Appropriate cut geometry may reduce correction before welding and improve the usefulness of fixtures and repeat assembly procedures.
Potential benefits include fewer manual transfers, less repeated marking, more consistent joint geometry, reduced corrective grinding and faster preparation for assembly.
Plasma does not guarantee a weld-ready edge on every material. Dross, oxide, bevel variation and other conditions may require cleanup. Follow the drawing and welding procedure for preparation, root opening, bevel geometry and cleanliness.
The strongest demonstration is your actual joint, cut in your intended material and checked against your assembly requirements.
Where CNC plasma can be a good fit
Evaluate the process for handrails, guardrails, tube intersections, structural fabrication, equipment frames, agricultural and trailer components, and repeated holes, slots or notches.
It can make sense where manual layout, coping and correction consume substantial labor. A simple straight cutoff may still be efficiently produced on a saw. Small precision holes, critical sealing features and tight-tolerance surfaces may require another process.
Questions to ask before ordering
- Can it process our material? Supply grade, dimensions, wall, stock length and weight.
- Can the software use our files? Demonstrate actual files and identify required preparation.
- What is included? Itemize the source, head, software, licenses, supports, handling equipment and optional processes.
- What cut quality can we expect? Agree on dimensional, hole-quality and edge requirements.
- What installation is required? Review electrical service, air or gas, extraction, guarding, fire precautions and handling.
- What training and support are included? Confirm installation, operator training, software assistance, consumables and service.
Plasma produces fumes, arc radiation, sparks and hot material. Stainless, galvanized and coated materials require appropriate exposure controls. Budget for the extraction and safety installation, not only the machine.

Measure the complete process
Compare the current layout, cutting, coping, feature-making, cleanup and fit-up work with the proposed CNC process—including programming, loading, unloading, inspection and finishing.
Measure total labor per accepted part, complete cycle time, material use, consumables, rework, changeover and assembly preparation. Torch speed alone does not describe the return on investment.
The ErcoCut advantage
The value comes from combining design and import software, controlled positioning and repeatable cutting. For a shop relying on manual templates and repeated layout, that combination can reduce preparation work and make repeat production more consistent.
Start with the drawing, demonstrate the software, cut a representative sample and measure the complete process.
