 | ◉ 120 A plasma cutting output Provides cutting power for workshop plate and fabrication jobs. ◉ High-frequency non-contact arc start Starts cutting without touching the torch tip to the workpiece. ◉ 60% duty cycle at 40°C Supports longer work periods at the specified duty-cycle current. |
◉ CNC connection capability Can be integrated with a compatible CNC cutting system. ◉ Preset cutting current Set the cutting current before starting the cut. ◉ 2T/4T trigger modes Use trigger-hold control for short jobs or latched control for longer runs. ◉ Adjustable cutting post-flow Set the airflow after cutting to balance torch cooling and air use. |  |
 | ◉ Dual IGBT modules Supports sustained cutting work within the rated duty cycle. ◉ Isolated torch switch circuit Helps reduce electromagnetic interference in the trigger circuit. ◉ 5 m P80 torch and 2 m ground cable included Provides working reach for cutting larger workpieces. |
Q1. What is the LGK-120A plasma cutter used for? A1. It is designed for heavy-duty plasma cutting in steel fabrication, structural steel processing, industrial maintenance, manufacturing, and repair applications.
Q2. What input voltage does it require? A2. The machine requires 380V three-phase input power, making it suitable for industrial workshops, fabrication facilities, and production environments.
Q3. Is this plasma cutter suitable for heavy-duty industrial cutting? A3. Yes. With up to 120A output, a 60% duty cycle, and a cutting capacity of up to 50mm, it is designed for demanding industrial cutting applications.
Q4. How thick can it cut? A4. The rated cutting capacity is up to 50mm. Actual cutting performance may vary depending on material type, air supply quality, cutting speed, and operating conditions.
