LGK-130IGBT Inverter Air Plasma Cutter

Inverter Air Plasma Cutting Machine

Inverter air plasma cutting machine LGK-130IGBT. Single-phase 220 V or three-phase 380 V / 220 V supply. Functions: Cut / Grid / Marking / Gouge. Design features - 100% duty cycle, suited to heavy industrial work - Current ramp-up technology that reduces torch consumable wear - Wide supply-voltage tolerance - Engineered dust-proof layout for high machine reliability - Compact, low-volume and lightweight construction, mountable on a CNC machine - Uses low-cost compressed air as the cutting gas, keeping running cost low - Accurate stepless presetting of cutting current - Plasma gas pressure detection and indication, plus a gas-test function for easy pressure setting - Automatic protection against over-temperature, over-voltage, under-voltage and phase loss Applications For manual and machine cutting of carbon steel, alloy steel and non-ferrous metals. Widely used in boiler and chemical plant construction, pressure-vessel fabrication, industrial power-plant installation, metallurgical and chemical construction, aerospace, automotive manufacturing and repair, and building decoration, and across all industries involving metal cutting. Why 130 A 130 A is chosen when production cutting speed on 12-25 mm plate matters more than portability. It is a common fitment on CNC cutting tables in steel service centres, where the machine runs most of the shift and pierce time is a measurable part of the cycle. Dual-voltage input covers both single-phase workshops and three-phase production sites.

  • Plasma gas pressure detection and indication with gas-test function
  • Automatic over-temperature, over-voltage, under-voltage and phase-loss protection
  • Accepts single-phase 220 V or three-phase 380 V / 220 V supply
  • 130 A output optimised for production cutting speed on 12-25 mm plate

Typical Applications

  • Medium plate processing and batch part cutting
  • Construction machinery and special vehicle structures
  • Ship panels and bridge member preparation
  • Heavy plate site cutting in metallurgical and chemical construction

Selection & Setup Notes

130 A suits shops doing batch cutting: parts completed per shift are often a third higher than at 100 A. If you are weighing up a table, see the CNC table versus handheld throughput and payback analysis. Full range: inverter air plasma cutters.

Standards & Further Reading

External reference: ISO 9013 — Thermal cutting classification — ISO 9013 defines the quality classes for thermal cut surfaces (perpendicularity, bevel, dross).

Frequently Asked Questions

Does 130 A need three-phase power?

Yes. At 130 A and above, specify three-phase 380 V; single-phase becomes the limiting factor through service capacity and voltage drop.

What settings do I need for 30 mm plate?

Match torch height, cut speed and gas pressure together, and set pierce height and dwell for thick plate. Run a coupon parameter matrix before production.

How do I reduce dross?

Check gas pressure first, then excessive speed and excessive standoff, then worn consumables. The systematic approach is in our cut-quality troubleshooting article.
