LGK-120 Digital Plasma Cutting Machine
Sichuan Morrow Welding Development Co., Ltd. focuses on the production and sales of welding power sources and related equipment. Our products are used in steel, shipbuilding, petroleum, smelting and other industries. Morrow Welding has stable markets in Europe, America, Asia and the Middle East.
The LGK series is a digital cutting machine designed for industrial metal cutting. The series includes LGK-100, LGK-120, LGK-160, LGK-200, LGK-250, LGK-315, LGK-400 and LGK-500 models. The rated cutting current ranges from 100A to 500A. This gives customers more choices for different cutting jobs and material thicknesses.
Stable Cutting Performance
A good cutting machine needs stable arc performance during long working hours. The LGK digital cutting machine uses HF arc ignition and a low-current starting function. The source states that the HF arc ignition has a success rate of more than 95%. This helps the cutting machine start the arc smoothly and reduce problems during cutting.
The cutting machine also has current ramp-up technology. It helps reduce spatter and consumable wear. The pre-gas and post-gas functions help protect the nozzle and electrode. The source states that these functions can extend nozzle and electrode life by more than 30% compared with competitors.
Digital Control and Easy Operation
The LGK cutting machine uses digital control for simple operation. Users can preset the cutting current and time for repeat jobs. The machine can also keep the settings after a power outage, which helps reduce repeated setup work.
The cutting machine supports both 2T and 4T modes. These modes give operators simple control for different cutting tasks. The digital display also shows error information. When a problem happens, the cutting machine can identify common issues such as short circuit, overheating and low gas pressure.
Wide Material Application
The LGK cutting machine can be used for many metal materials. The product information lists mild steel, stainless steel, alloys and aluminum. The LGK series can be used for aluminum cutting up to 120 mm thick according to the provided product information.
Because of this wide material range, the cutting machine can be used in different industrial applications. It can support metal processing work in steel fabrication, shipbuilding, petroleum equipment, smelting and other workshops.
Ready for Automated Production
The LGK cutting machine is also designed for modern production lines. It provides arc-start signals and interfaces for robot integration. This allows the cutting machine to work with automation systems and helps customers build more efficient cutting processes.
The cutting machine also uses EMC shielding. This helps reduce interference when the machine works in electrically noisy industrial environments. Gas and cooling safety functions check air or water pressure automatically to help protect the machine during operation.
Built for Industrial Use
The LGK cutting machine has a 60% duty cycle for sustained industrial operation. It also uses F-Class insulation and an IP21S protection rating. These features help the cutting machine work in demanding workshop conditions.
The LGK cutting machine is available with different rated cutting currents from 100A to 500A. The input power source is 3-phase 380V, 50/60Hz. The rated work voltage varies by model, from 120V to 230V.
Morrow Welding continues to improve its welding and cutting equipment for industrial customers around the world. With stable performance, digital control, wide material application and automation support, the LGK cutting machine is a practical choice for professional metal cutting.
