Hebei Juliang Technology Co., Ltd. is one of the leading manufacturers and suppliers of light gantry plasma cutter 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.

product brief introduction

A Light Gantry Plasma Cutter is a CNC thermal cutting system. It operates on a bridge-like gantry that stretches over your workpiece. This gantry moves along floor rails while the plasma torch traverses the material. A CNC controller manages all movements, torch activation, gas flow, and height adjustments automatically.

This machine can perform both plasma and oxy-fuel cutting in a single setup. Plasma is ideal for cutting thin to medium plates quickly, while oxy-fuel is more economical for thicker plates, though slower. You can switch between cutting methods without needing to reposition the material.

Who can benefit from this Light Gantry Plasma Cutter?

Smaller and mid-sized fabrication shops that require CNC cutting but can't afford a large industrial machine.
Steel service centers that cut plate for their customers. If you're in steel distribution, you need a machine capable of handling diverse cutting needs, and this light gantry provides that without a hefty investment.
Shops offering contract cutting services across different industries. With its ability to perform both plasma and flame cutting, you can accept jobs involving thin materials as well as thick plates, eliminating the need for multiple machines.
Maintenance and repair departments that need to fabricate replacement parts on demand. It's compact enough for smaller workshops and straightforward enough for operators to master within a week.

Installation: Required Conditions

Basic Requirements

A stable foundation is necessary. When the track spacing is 3 meters, the cutting width is approximately 2.5 meters (track spacing minus about 500 millimeters). The SK series is usually equipped with a configuration of 3000×1500 millimeters (SK-3015).

Required Space

A standard equipment with a track spacing of 3000 millimeters and a track length of 8000 millimeters requires approximately 4×9 square meters of floor space. Please reserve additional space for material handling and daily access.

Power Supply Requirements

The equipment operates on an AC 380V three-phase power supply. The plasma system consumes a lot of power. For example, a 65A system requires approximately 380V three-phase power supply.

Gas Supply

Cutting carbon steel requires oxygen, while stainless steel requires nitrogen. Ensure that both gases are clean and dry. Any moisture in the pipes may quickly damage the consumable materials.

Installation Time

Thanks to its lightweight design, the assembly speed of this equipment is much faster than that of heavy gantry frames. From installation to the first cut, it is expected to be completed within 3 to 5 working days.

What Wears Out

Plasma cutting consumables are mainly electrodes and nozzles. If you're cutting daily, you'll likely need to replace them every 1-2 weeks. You'll know it's time when the arc starts to stray or your cut quality declines.

Oxy-fuel tips also wear down due to heat and require periodic replacement. For daily use on thick plate, plan to change them every few weeks.

Periodically inspect the torch body. Look for loose connections, damaged cables, and wear on the ceramic shield.

Rails and bearings need consistent cleaning and lubrication. The lighter rails on lighter gantries, compared to heavier machines, mean you'll need to clean them more often to keep debris from building up.

Anti-collision Holder

If the torch hits the plate, the anti-collision holder will automatically stop it, saving the cutting head from damage.

FAQ

Can I cut expanded metal or mesh with this machine?

No. The open pattern causes the arc to jump and wander. You'll get poor results and burn through consumables fast. Plasma cutters need solid, continuous material to cut properly.

What's the most common source of problems with the torch height control?

Bad arc voltage feedback. The height control measures arc voltage to determine torch height. If your ground connection is poor or your gas pressure fluctuates, the voltage reading drifts and the torch moves to the wrong height. Check your ground clamp and gas supply first when height control acts up.

Can I use the Light Gantry Plasma Cutter for gouging or scarfing?

You can, but you'll need a different torch and settings. Gouging removes material rather than cutting through it - useful for weld preparation and defect removal. The power supply supports gouging with the right setup.

How do I know if my air quality is good enough?

Check the color of your cut edge and the condition of your consumables. If you're replacing nozzles daily or your cut edge has a rough, oxidized finish, your air quality is suspect. Install a refrigerated air dryer and check your filters regularly.
