 | ◉ Plasma cutting and MMA welding Cut and weld with one machine to save equipment space. ◉ Up to 65 A cutting and 160 A MMA output at 380 V Provides capacity for plate cutting and workshop welding. ◉ 60% duty cycle at 40°C Supports longer work periods at the specified duty-cycle current. |
◉ Built-in 1100 W air pump Supplies cutting air without a separate compressor. ◉ Preset cutting current Set the current before cutting to suit the workpiece. ◉ Stable cutting current Helps keep the cut consistent as the torch moves. |  |
 | ◉ Overheat and overcurrent protection Helps protect internal components from overheating and excessive current. ◉ 5 m P80 torch and 2 m ground cable included Provides practical reach around larger workpieces. ◉ 220/380 V input options Works with either supported voltage for use at different job sites. |
Q1. What functions does the LGK-80S support? A1. The LGK-80S combines plasma cutting and DC MMA stick welding in a single machine, allowing users to perform both cutting and welding tasks with one power source. Q2. What input voltages does the LGK-80S support? A2. The machine operates on single-phase 220V, dual-phase 380V, and three-phase 380V power supplies at 50/60Hz, providing flexibility for different workshop and industrial environments. Q3. What are the cutting and welding output ratings? A3. On 220V input, the machine provides 55A plasma cutting output and 180A MMA welding output. On 380V input, it provides 65A plasma cutting output and 180A MMA welding output. Q4. What cutting thickness can the LGK-80S handle? A4. The machine is designed for cutting applications on conductive metals with thicknesses from 1–25mm. Actual cutting performance depends on material type, air supply quality, and operating conditions. Q5. What materials can the LGK-80S process? A5. The plasma cutting function is suitable for conductive metals, while the MMA welding function is intended for steel fabrication, repair, maintenance, and installation applications. Q6. What accessories are included? A6. The standard package includes a plasma cutting torch, ground cable, and related cutting accessories. Please confirm the exact package contents with your supplier before ordering. Q7. Does plasma cutting require compressed air? A7. No. LGK-80S is internal air pump cutting machine. Q8. What is the advantage of the built-in air compressor? A8. The integrated air compressor helps reduce equipment requirements and simplifies machine setup compared with plasma cutting systems that rely entirely on separate external air sources. Q9. What are the key technical specifications? A9. The LGK-80S is built with IGBT inverter technology, providing stable cutting and welding performance, efficient power conversion, and reliable operation. Q10. Who is the LGK-80S best suited for? A10. The LGK-80S is suitable for fabrication workshops, maintenance departments, equipment repair facilities, construction projects, and metalworking operations that require both plasma cutting and MMA welding capabilities in one machine. |
