Hebei Juliang Technology Co., Ltd. is one of the leading manufacturers and suppliers of variable frequency air 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.
Let me start with an honest question.
How many times has your current plasma cutter shut down in the middle of a job because it got too hot? Once a week? Twice?
That's exactly why I want to talk to you about this machine.
Why I'm Reaching Out
I'm on the sales team at Hebei Juliang. We've been building cutting equipment since 2014. I've seen what works in real shops - and what doesn't.
The Variable Frequency Air Plasma Cutting Machine I'm about to describe isn't new technology. Variable frequency has been around for years. What's different is how we've applied it to an air plasma cutter at this price point, with a 100% duty cycle, and backed it with service that actually answers the phone.
First, Let Me Show You What's Inside
Because what's inside determines how long this machine lasts in your shop.
|
Component |
What We Use |
|
Core components |
PCB board, wire coil, solenoid valve (industrial grade) |
|
Casing |
Yellow, high-visibility, impact-resistant |
|
Torch |
7 meters, flexible, non-contact pilot arc |
|
Cooling |
Fan-cooled power supply, air-cooled torch |
|
Insulation |
Class F |
|
Protection rating |
IP21S |
That solenoid valve - competitors often use a cheaper version. We don't. Because when that part fails on a Friday afternoon, your weekend batch stops. And I don't want that call from you.

That 100% duty cycle means you can run this machine all shift - eight hours, ten hours - and it won't stop to cool down. The 65A output covers most shop work from 3mm sheet up to 14mm plate. And compressed air only means no specialty gas bottles to manage.
Where Shops Actually Use This Machine
I don't want to give you a generic list of industries. Let me tell you specific jobs where this machine saves real time.
On a ship repair dock – You're cutting through 8mm hull plate to remove a damaged section. The metal is painted and has surface rust. The non-contact pilot arc fires immediately. No scraping. No re-striking. The 7-meter torch reaches into a tight compartment without dragging the unit behind you.
At a steel structure yard – You're fabricating base plates from 12mm mild steel. The quality cut at 500mm/min leaves minimal slag. That means less grinding time. Your fitter moves to the next piece faster.
On a bridge construction site – Power sources are inconsistent. This machine accepts both 220V and 380V three-phase. You plug into whatever is available. No electrical rework. No delays.
In a mining equipment repair bay – A haul truck's wear plate needs replacement. The machine runs for six hours straight cutting 10mm and 16mm in the same shift. The 100% duty cycle never triggers thermal protection. The truck goes back to work that same day.
In an automotive fab shop – You're prototyping a new chassis bracket. One day it's 3mm stainless. The next day it's 6mm mild steel. The variable frequency design keeps the arc stable across thickness changes. You don't fight the machine to get a clean edge.
In a general job shop – HVAC ductwork, custom signs, equipment guards, furniture frames. One machine handles handheld cutting and can later integrate with a CNC table when you grow. The arc voltage output signal (1:1, 1:20, 1:50, 1:100) is already there.
How We Built This Machine - Company Strength
I mentioned we started in 2014. Here's the timeline that matters to you.
2014 – Entered CNC cutting field, launched portable cutting machine
2015 – First factory expansion, gantry cutting machine launched
2018 – Second expansion, established Hebei Juliang Technology Co., Ltd., registered "Xin Juliang" brand
2020 – Increased R&D investment, obtained multiple invention and utility model patents
2022 – Launched foreign trade, awarded high-tech enterprise status
2025 – Third factory expansion, rated as large-scale enterprise and specialized/refined/innovative enterprise
Today our factory has large laser cutting machines, gantry milling machines, swivel arm drilling machines, laser welding machines, and high-precision collimators.
We hold CE certification, invention patents, utility model patents, and the high-tech enterprise title.
What Our Customers Say - Direct Quotes
"I've owned three plasma cutters over ten years. The Variable Frequency Air Plasma Cutting Machine is the first one that didn't need a repair in its first year. The duty cycle is real. I tested it."
- Fabrication shop owner, Eastern Europe
"The non-contact start cut my torch consumable costs by more than half. That alone paid for the upgrade in four months. The rest is savings."
- Mining equipment repair, Africa
"I run a small job shop. I don't have a service department. When I had a settings question, I called their support line. An engineer answered and did a remote video session in ten minutes. Fixed it without sending anyone onsite."
- General fabrication, Southeast Asia
Service That Starts When You Buy, Not When Things Break
Service support begins at the moment of purchase, not ends at the moment of purchase.
Here's what that actually means for you.
If a part fails – You call or email. After-sales engineer assesses. We ship the part and guide you through replacement remotely. No waiting for a technician to fly in.
If the unit needs factory repair – You pack and ship. We receive, test, and diagnose. Under warranty? Free repair. Out of warranty? We quote before work starts. After repair, burn-in test, packing, shipping, and notification at every step.
If you want to test before buying – Our showroom has multiple machine models. Bring your material or send it to us. Free sample making service. You see the cut quality before you spend a dollar.
If you need technical help at 9 PM – Multiple engineers provide 24-hour free remote video technical support. Night shift? Weekend? We're here.
Three Questions Shops Ask Me Most
Q: Does the variable frequency feature actually make a difference in daily cutting?
A: Yes - but let me be specific. If you cut the same thickness every day, you'll notice the lower power draw and stable arc. If you switch between 3mm sheet and 12mm plate in the same shift, you'll notice the arc stays consistent without constant adjustment. That's where the Variable Frequency Air Plasma Cutting Machine separates from fixed-frequency units.
Q: What's the real warranty coverage, not the marketing version?
A: Two years on the complete unit. That covers the PCB board, wire coil, solenoid valve, and all core components. Mechanical test reports and factory video inspection records are available before you buy. No hidden exclusions.
Q: Can this machine connect to my CNC table if I automate later?
A: Yes. The arc voltage output signal supports 1:1, 1:20, 1:50, and 1:100 ratios (system default 1:1). Many customers start with handheld cutting, then add a gantry system later. The same machine serves both roles.
