Hebei Juliang Technology Co., Ltd. is one of the leading manufacturers and suppliers of huayuan portable plasma cutting machine in China. Please feel free to buy CE approved machinery made in China here from our factory. All customized machines are with high quality and competitive price.

What This Machine Actually Is

The Huayuan Portable Plasma Cutting Machine offers a lightweight, computer-driven cutting system that brings industrial-level plasma cutting to smaller workshops and job sites where a full-size gantry isn't feasible. This system cleverly combines a Huayuan plasma power source with an intuitive CNC control, all in a package designed for easy setup and portability.

Huayuan, the company behind the plasma power source, has been manufacturing welding and cutting equipment since 1993. They operate out of a substantial 57,200+ square meter factory staffed by over 400 employees, making them one of China's largest manufacturers in this sector. Their annual production reaches approximately 100,000 sets, and their LGK series plasma power sources are well-regarded for their steadfast reliability and strong performance.

How It Actually Works

The Huayuan plasma power source creates a hot electrical arc in compressed air, forming plasma at about 25,000°C. This plasma melts the steel, and a high-speed gas jet blows away the molten metal, completing the cut.

Your design file (often DXF or DWG from CAD) is read by the CNC controller, which directs the torch's movement. This process ensures precise, repeatable cuts that are immediately ready for further work.

Huayuan's unique selling point is their proprietary compressed air cooling. It boosts consumable lifespan by up to 2.8 times; a set usually good for 350 cuts can now manage up to 950 arc starts.

Users can customize gas pre-flow, post-flow, and current up-slope timing based on the torch cable length. The plasma gas pressure is adjustable and visible on a panel meter for easy operation. A torch monitoring function also signals when consumables need replacement.

Where Shops Actually Use This

Small to medium fabrication shops. Brackets, frames, gussets, structural components. The machine pays for itself.

Steel structure fabrication. Connection plates, beam flanges, column base plates.

Shipbuilding and repair. Cutting plates for hull sections, bulkheads, deck components.

Construction and heavy equipment. Cutting structural components for buildings and mining equipment.

Farm equipment repair.

Automotive parts. Chassis components, brackets, custom parts.

Getting It Set Up

our Huayuan Portable Plasma Cutting Machine arrives in several parts. Here's a quick rundown of what to expect

Preparation

Clear a space. Ensure the floor is level (no special reinforcement needed, just level).
Power: You'll need 220V or 380V, depending on your setup.

Compressed air for the plasma needs to be clean and dry. (Note: the LGK-100P1 has its own air pump, so no external air is required for that model.)

Assembly

Bolt the track sections together to match your desired cutting length.
Mount the gantry onto the rails.
Install the torches and height controller.
This usually takes about half a day with remote assistance.

Software

Install FastCAM or StarCAM on your computer.
You can then import your CAD files or use the included shape library.
Transfer your designs via USB.

First Cuts

Perform test cuts on scrap material.
Tweak the settings and fine-tune the height controller as needed.

Everything You Need to Know

Can I cut stainless steel and aluminum?

Yes - with plasma, stainless and aluminum are conductive and cut well. Stainless needs different gas settings than mild steel. Flame cutting only works on carbon steel - it won't cut stainless or aluminum.

Does the plasma cutting machine need regular calibration?

Yes. It is recommended to perform an accuracy calibration every 3 to 6 months to check if the cutting torch movement trajectory is consistent with the program settings. The simplest calibration method is to cut a 50×50mm square, and then use a caliper to measure the actual size and the deviation from the program. If the deviation exceeds 0.5mm, the motor step angle needs to be adjusted or recalibrated. If the equipment is used every day, the frequency can be higher.

Why are the plates cut with the same parameters sometimes good and sometimes bad?

The biggest variable is the steel plate itself. Different batches of steel have different carbon contents, silicon contents, and minor differences in rolling processes, all of which can affect the cutting result. Some steel plates have high internal stress and will deform after cutting. This is not a problem with the machine; it's a problem with the material. If you find that the same set of parameters results in different cutting effects for different batches of plates, first adjust the cutting speed (±10%) instead of the power. If the steel plate surface is rusty, it will also affect the consistency of the cutting.

Is the after-sales service response fast?

We offer remote video support and telephone support. Most issues can be resolved through remote diagnosis, such as parameter settings, system fault troubleshooting, operation guidance, etc.

If you're in the steel plate cutting business and have been holding off on buying a CNC machine due to concerns about its size or price, we'd love to hear from you.

Describe your typical cuts, the material thickness, and plate dimensions. We'll provide a clear assessment of whether a Huayuan Portable Plasma Cutting Machine is suitable for your needs. If not, we'll suggest alternative solutions.
